The Restoration of Priesthood Keys on Easter 1836, Part 2: Symbolism of Passover and of Elijah’s Return
On Easter Sunday, 3 April 1836, the Savior, Moses,
 Elias, and Elijah appeared in succession in the Kirtland Temple and 
restored priesthood keys required for the dispensation of the fulness of
 times. (See D&C 110.) Elijah’s coming had been prophesied more than twenty-two centuries earlier by Malachi. (See Mal. 4:5; D&C 110:14.)
This
 article reviews the importance of that restoration and suggests that it
 occurred on a day chosen in part because of its symbolic significance. 
To help us appreciate this symbolism, it will be shown that even the 
timing of the Lord’s death and resurrection
 was foreshadowed in the Passover ceremony. Then the return of Elijah, 
which the Jews have long anticipated at Passover, will be discussed, as 
well as the symbolism of the day Elijah returned in 1836.
The
 reader should keep in mind that the topics addressed in this article 
are complex, and that some of the evidence employed is by its nature 
inexact; nevertheless, the reader may well find the proposed conclusions
 to be of serious interest. (See note
 1
      for further discussion on the nature of the evidence dealt with in this article.)
Passover Symbolism
In Part 1 it was proposed that the Savior’s resurrection occurred on the Sunday after Passover, 16 Nisan, or 3 April A.D. 33 on our Gregorian calendar.
   2
  But the relationship of his resurrection to the Jewish Passover is much more than just a coincidence of dates.
The
 Lord instituted the Passover celebration at the time of the exodus of 
the Israelites from Egypt, to commemorate their release from slavery 
after the angel of death slew the firstborn of Egypt but “passed over” 
the Israelite homes. (See Ex. 12.)
 However, as the symbolism of the Passover is reviewed, it will be clear
 that the Passover ceremony is not only symbolic of the redemption of 
Israel from bondage, it also was in similitude of the redemption of 
mankind from death and sin by the Lamb of God.
The
 prophets taught that the ordinances of the law of Moses (such as 
Passover) were symbolic of things to come. For example, Abinadi 
explained that “there was a law given them [the children of Israel], 
yea, a law of performances and ordinances, … all these things were types
 of things to come.” (Mosiah 13:30–31.)
 He summarized his powerful discourse, which condemned the wicked 
priests for not teaching the prophetic nature of the law of Moses, with 
the following closing statement: “Therefore, if ye teach the law of 
Moses, also teach that it is a shadow of those things which are to 
come—Teach them that redemption cometh through Christ the Lord.” (Mosiah 16:14–15; see also Mosiah 13:30–33.)
Similarly, Paul taught that the Law of Moses “was our schoolmaster to bring us unto Christ” (Gal. 3:24), and that it was “a shadow of good things to come” (Heb. 10:1).
How
 was the annual Passover ceremony a shadow of the redemption that would 
come through Christ? The Passover ceremony will now be reviewed to see 
how it symbolized not only the elements of the Atonement, but also their
 precise timing. (See “Calendar” and “Feasts” in the Bible Dictionary, LDS edition.)
The
 Passover feast centered on the paschal lamb, which was a sacrificial 
lamb, a male without blemish and with no broken bone, even after death. 
(See Ex. 12:5, 46.) Likewise, Jesus was the “Passover,” the “Lamb of God” (1 Cor. 5:7; John 1:29), a male without blemish and with no broken bone, even after death (John 19:36). He was the Firstborn of God in the premortal existence (D&C 93:21), sanctified in the flesh as were the firstborn of Israel (Ex. 12:23–24), and slain even as were the firstborn of Egypt (Ex. 12:29).
The
 Passover lamb was to be chosen on 10 Nisan, the tenth day of the Jewish
 lunar month Nisan. It was to be killed by “the whole assembly of the 
congregation of Israel” on 14 Nisan (Ex. 12:6),
 which was usually the day of the first full moon of spring. Jewish 
sources state that the lamb was sacrificed between 3:00 and 5:00 P.M. on that day.
   3
 
Jesus, too, was “chosen” on 10 Nisan
   4
  at his triumphal entry into Jerusalem, when he was hailed as the Messiah (see Matt. 21:1–9; Mark 11:1–11; Luke 19:37–40; John 12:12–16), which had been prophesied by Zechariah (Zech. 9:9).
 The multitude who had assembled in Jerusalem for Passover later 
consented to his death when they “all” cried out on 14 Nisan, “Let him 
be crucified.” (Matt. 27:20–23.) The Lamb of God died about 3:00 P.M. (Matt. 27:46) on the day of preparation for Passover (John 19:14), 14 Nisan, just when the paschal lambs were also being slain.
Of
 course, at the triumphal entry the multitude did not understand that 
they were choosing the Lamb of God to sacrifice, but believed they were 
choosing a king (Luke 19:38)
 whom they expected to liberate them from Roman rule. And at the 
Crucifixion they were unaware that they were sacrificing the Lamb of 
God, but believed they were slaying an imposter who could not even save 
his own life. (Matt. 27:41–44.)
The
 preparation of the lamb for the feast had to be hurriedly completed 
before sunset, after which would begin the first day of Passover, 15 
Nisan, a day sanctified as a special Sabbath day. After sunset, the lamb
 was eaten with bitter herbs, unleavened bread, and wine. This 
ritualized Passover meal was also called the feast of unleavened bread; 
it began a week in which no leavened bread was eaten, symbolic of the 
haste of preparation which did not allow enough time for bread dough to 
rise. (Ex. 12:18–20, 34, 39; Lev. 23:6–8.)
Likewise,
 the body of Jesus had to be hurriedly prepared for burial before the 
sunset would commence the Sabbath, which would be a “high day” (John 19:31) because it was not only Saturday, the weekly Sabbath, but also 15 Nisan, the first day of Passover.
It
 was on 15 Nisan, after the slaying of the firstborn, that Pharaoh 
declared liberty to the captive Israelites. After their long period of 
bondage in Egypt, it must have been a day of great rejoicing. One reason
 that 15 Nisan was sanctified as an annual feast day was to commemorate 
that day on which the Lord brought Israel out of bondage and released 
them from the chains of slavery. (See Ex. 12:14–17, 29–31; Ex. 13:3, 14–15.)
Similarly, on 15 Nisan A.D.
 33, the Passover feast day, the Savior declared liberty to the captives
 in the spirit prison after their long period of bondage. (See D&C 138:18, 31, 42.)
 Before the Savior arrived, they had been “assembled awaiting the advent
 of the Son of God into the spirit world, to declare their redemption 
from the bands of death.” In fact, they were already “rejoicing in the 
hour of their deliverance from the chains of death.” (D&C 138:16, 18.)
 The fact that they were assembled, rejoicing in the hour of their 
deliverance, suggests that they expected his arrival on the Passover 
feast day, the day of liberation.
The
 law of Moses states that “on the morrow after the sabbath” of Passover,
 the priest should wave before the Lord a sheaf of the firstfruits of 
the harvest.
   5
  (See Lev. 23:10–12.) On Easter Sunday, 16 Nisan, the morning after the Jewish Sabbath,
   6
  the Savior, through his resurrection, became “the firstfruits of them that slept.” (1 Cor. 15:20, 36–38.)
 Jesus had already taught that he was like a kernel of grain which must 
abide alone until it dies in the ground, whereupon it can bring forth 
much fruit. (See John 12:23–24.)
 Lehi also explained that the Savior, “being the first that should rise …
 is the firstfruits unto God, inasmuch as he shall make intercession for
 all the children of men; and they that believe in him shall be saved.” (2 Ne. 2:8–9.)
Thus,
 the carefully prescribed elements of the Passover ceremony precisely 
foreshadowed both the events of the Atonement and the time each would 
occur. The annual sacrifice of the paschal lamb on 14 Nisan was not only
 in remembrance of the Israelites’ having been saved by the blood of the
 lamb on the houses in Egypt (Ex. 12:13),
 it was also anticipating the 14 Nisan when the great sacrifice of the 
Lamb of God would occur. The feast on 15 Nisan celebrated not only the 
liberation of the captives of Egypt; that day would also be the time of 
even more rejoicing when the Savior would declare liberation to the 
captives in the spirit prison. And the third day, 16 Nisan, was not only
 the time when the firstfruits of the harvest of barley were presented 
to the Lord, it was also the glorious day of the Resurrection—the 
firstfruits of the harvest of souls.

calendar, according to the chronology proposed in Part 1 of this series.

When
 it is thus understood how the Passover ceremony of the law of Moses was
 fulfilled in the resurrection of Christ, one finds further confirmation
 of the proposed Resurrection date in what is termed an “argument from 
typology.” For example, the fact that the law of Moses specifically 
required the lamb to be sacrificed on 14 Nisan argues against a 15 Nisan
 Crucifixion (a possibility discussed in Part 1). Moreover, when the 
symbolism of the offering of the firstfruits on the morning after the 
Jewish Sabbath is understood to symbolize the resurrection of the 
Savior, then it becomes an indication that the first Easter morning 
should also have occurred at the same time.
   6
 
The
 importance of the Savior’s resurrection occurring on Sunday was 
emphasized when the sanctified Sabbath day was changed from Saturday, 
the seventh day, symbolic of the day of rest from the labor of the 
Creation (Ex. 20:11), to Sunday, the Lord’s Day (Acts 20:7; D&C 59:12), the glorious day of the Savior’s resurrection.
The
 Easter story has two main parts: the Savior’s suffering and his 
triumph. The emblems of the sacrament remind us of his suffering, both 
in body and in spirit. (See D&C 19:18; D&C 20:75–79.)
 The Sabbath was changed to Sunday as a reminder of the day of triumph, 
the day death was conquered. In a sense, one celebrates Easter every 
Sunday by partaking of the sacrament.
Thus,
 it is clear that the Lord uses symbols to remind his people of the key 
points of the Atonement, even of the day it was completed. The day of 
Jesus’ resurrection was important enough to commemorate beforehand in 
the Passover ceremony and also to celebrate afterward by changing the 
Sabbath to Sunday.
Now
 the importance of another Easter event, the return of Elijah, will be 
reviewed, and then the significance of the date it occurred will be 
discussed.
The Return of Elijah
The
 closing words of the Old Testament contain Malachi’s promise that 
Elijah the prophet would be sent before the Messiah to fulfill an 
important mission:
“Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the Lord.
“And
 he shall turn the heart of the fathers to the children, and the heart 
of the children to their fathers, lest I come and smite the earth with a
 curse.” (Mal. 4:5–6.)
Malachi’s words were considered so important that the Savior gave to the Nephites all of chapters 3 and 4 of Malachi [Mal. 3, 4], which end with this prophecy of Elijah’s return. After commanding them to write the words (3 Ne. 24:1),
 he explained, “These scriptures, which ye had not with you, the Father 
commanded that I should give unto you; for it was wisdom that they 
should be given unto future generations.” (3 Ne. 26:2.)
Clearly,
 Elijah’s return would be an important event in the restoration that 
would precede the Savior’s second coming. The first prophecy that Moroni
 quoted to Joseph Smith was the prophecy of Malachi (JS—H 1:36–39),
 with the final words modified in a way that clarifies the purpose of 
Elijah’s return. He would “reveal unto you the priesthood,” to “plant in
 the hearts of the children the promises made to the fathers,” and to 
turn the hearts of the children to their fathers. (D&C 2:1–2.)
The promise of Elijah, taught by the scribes in Jesus’ day, is still remembered by the Jewish people every year at Passover. A special place is set for him, with a cup of wine. At a prescribed time during the meal, the door is opened for him to enter.
The
 origin of the tradition that Elijah would return at Passover seems to 
have been lost in antiquity. It has been suggested that Elijah’s return 
was associated with Passover, the feast commemorating the redemption of 
Israel, because it would herald the coming of the Messiah, the Redeemer 
of Israel.
   7
 
Whatever
 the origin of the association of Elijah with Passover, the tradition 
was proved correct when Elijah did return at Passover in 1836. However, 
he did not return at the Passover meal, when the cup was offered on the 
evening of Friday, April 1.
   8
  Instead, he returned on Easter Sunday, the second day of 
Passover, the day of the presentation of the firstfruits of the harvest.
The
 long-awaited return of Elijah occurred in the Kirtland Temple on Easter
 Sunday, 16 Nisan, 3 April 1836. First the Savior appeared, followed by 
Moses, then Elias, and finally Elijah.
Moses
 restored the “keys of the gathering of Israel,” one of the necessary 
preparations for the Second Coming. These include the keys to gather 
scattered Israel from the four quarters of the earth and to lead the Ten
 Tribes from the land of the north. (D&C 110:11.)
Elias
 “committed the dispensation of the gospel of Abraham, saying that in us
 and our seed all generations after us should be blessed.” (D&C 110:12.)
Elijah
 restored “the power to hold the key of the revelations, ordinances, 
oracles, powers and endowments of the fulness of the Melchizedek 
Priesthood and of the kingdom of God on the earth; and to receive, 
obtain, and perform all the ordinances belonging to the kingdom of God, 
even unto the turning of the hearts of the fathers unto the children, 
and the hearts of the children unto the fathers, even those who are in 
heaven.”
   9
 
The
 Prophet Joseph Smith explained that “the spirit of Elias is first, 
Elijah second, and Messiah last. Elias is a forerunner to prepare the 
way, and the spirit and power of Elijah is to come after, holding the 
keys of power, building the Temple to the capstone, placing the seals of
 the Melchizedek Priesthood upon the house of Israel, and making all 
things ready; then Messiah comes to His Temple, which is last of all.”
   10
 
Thus,
 the coming of Elijah on 3 April 1836 was to occur after forerunners had
 returned in the spirit of Elias to prepare the way. (See D&C 27:6–7; D&C 128:20–21.)
 At his return, Elijah declared: “Therefore, the keys of this 
dispensation are committed into your hands; and by this ye may know that
 the great and dreadful day of the Lord is near, even at the doors.” (D&C 110:16.) With the keys of the dispensation of the fulness of times (D&C 112:30) restored, the Church would then “build up the kingdom before the coming of the great day of the Lord.”
   11
 
Now
 a further witness from astronomy will be presented, showing that the 
Easter of Elijah’s return was a most remarkable anniversary of the day 
of the Savior’s resurrection.
An Astronomically Rare Easter
Ancient
 prophets had revelations concerning the use of astronomy for reckoning 
time. Abraham, for example, was given to know the “set times” of the 
earth, moon, and sun, and then was shown that these “lights in the 
expanse of the heaven” were to be “for signs and for seasons, and for 
days and for years.” (Abr. 3:6; Abr. 4:14.) In obedience to the Lord’s direction, Abraham then taught these principles of astronomy to the Egyptians (Abr. 3:15; see also Facsimile 3), who in turn may have taught them to Moses, who was raised as Pharoah’s grandson (Ex. 2:10). Moses also received revelations mentioning the use of the sun and moon to reckon time (Moses 2:14), which became very important in determining sacred days according to the law of Moses (see Lev. 23).
The Jewish lunisolar calendar uses three of the cycles that were revealed to Abraham (see Abr. 3:1–18): the day is reckoned principally by the earth’s rotation, the month by the moon’s phases, and the year by the sun’s apparent annual motion.
Even
 in our day, the Lord has promised that “all the days of their days, 
months, and years, and all their glories, laws, and set times, shall be 
revealed in the days of the dispensation of the fulness of times.” (D&C 121:31.)
As
 an astronomer who has studied the lunisolar calendar, I was intrigued 
by Elijah’s return occurring not only during Passover week, as 
anticipated by the Jews, but also on an Easter Sunday that was 
calendrically similar to the proposed date of the Savior’s resurrection,
 being both April 3 on the Gregorian calendar and 16 Nisan on the Hebrew
 calendar.
Was
 that merely a calendrical coincidence? Or could the timing of Elijah’s 
return have been purposely chosen to correspond to some special Passover
 in accordance with Jewish tradition? Pursuing these types of questions 
led me to discover an interval of time that is so remarkable in an 
astronomical sense that it seems to constitute evidence that the timing 
of Elijah’s return was carefully chosen.
Easter
 is always on Sunday, usually the first one following Passover, a 
calendrical choice that commemorates the Savior’s resurrection on 
Sunday. It can also serve as a reminder that he was crucified at the 
Passover, the ceremony foreshadowing his great sacrifice. Because of the
 relationship of Passover to the lunisolar calendar, Easter is usually 
the first Sunday after the first full moon on or after the spring 
equinox. Thus, the date of Easter varies from year to year, occurring 
between March 22 and April 25.
Accordingly,
 only about one Easter in thirty will fall on any particular day during 
that period, such as April 3. Moreover, not all Easters fall on the same
 day of the Judean month, but usually between 15 Nisan and 21 Nisan.
So, how often does Easter Sunday occur on both April 3 and 16 Nisan, as it did in A.D.
 33? It happens less than once every century, on the average. The year 
1836 was the only such occurrence in the nineteenth century.
Interestingly, the accuracy of the calendrical alignment between A.D.
 33 and 1836 is even more precise than to the very day. To understand 
this added precision, a new concept called a “realignment interval” will
 be defined and applied to the lunisolar calendar.
   
     Lunisolar Calendar Realignment Interval
   
 
When
 can Easter Sunday occur on 16 Nisan on the Jewish calendar and also on 
April 3 on our Gregorian calendar, which is based on the solar year? For
 such an occurrence, the interval between that Easter and Sunday, 16 
Nisan, 3 April A.D. 33 would have to equal a whole number of weeks, and of lunar months, and of solar years.
   12
  Accordingly, a “realignment interval” for the Jewish calendar is defined as a period of time such that no shorter period is so nearly an exact number of days, weeks, months, and years. (See “Realignment Intervals” sidebar for details.)
To the very day, the Easter of 1836 completed a Jewish calendar realignment interval of 1,803 years since the Easter of A.D. 33.
   13
  This fact has two consequences. First, the Jewish calendar would begin to repeat for several years.
   14
  Secondly, it means that the Easter of 1836 was calendrically the most similar in history to the Easter of A.D.
 33. And if the earth’s orbit continues unchanged, that Easter should 
retain this distinction for another three thousand years, when a better 
realignment interval is due.
From
 an astronomer’s point of view, this is no small coincidence. This 
result seems to clearly support the conclusion that it was not a matter 
of chance that Elijah’s return occurred on an Easter Sunday that was 
also 3 April and 16 Nisan, which is calendrically the same as the 
proposed date of the Resurrection. But before discussing some possible 
reasons for such an occurrence, let us discuss a second astronomical aspect of the timing of Elijah’s return.
   
     A Saros Century
   
 
The interval of 658,532 days
   15
  (1,803 years) between 3 April A.D. 33
 and 3 April 1836 is also impressive for an entirely different 
astronomical reason than that discussed above. To the very day, it is 
equal to 100 saros periods of 6,585.321 
days each. The saros is a period of 18.03 years known to astronomers as 
the interval in which solar or lunar eclipses often repeat.
   16
  (See “The Saros” sidebar for details.)
It
 should be emphasized that the fact that the same period of time (1,803 
years) can be equal both to a lunisolar calendar realignment interval and to 100 saros periods is very surprising because the length of the saros is also determined by other factors.
   17
 
Is
 there any astronomical significance to the number 100? Yes, it turns 
out that 100 saros periods is the realignment interval for a saros with 
the solar year. That is, if one counts saros periods from the lunar 
eclipse that occurred on the proposed date for the Crucifixion, 1 April A.D. 33, the first time that a saros would again begin on April 1 would be in 1836.
Note,
 however, that the saros alignment is only sufficient for eclipses to 
reoccur for up to 70 saros periods; thus, eclipses do not reoccur after 
100 saros periods.
   18
  On the other hand, the orbital alignment is close
 enough to produce an interesting calendrical alignment. After 100 saros
 periods, the lunar orbit is in about the same orientation relative to 
the sun, which causes the Judean calendar to also begin to repeat 
(because it uses the actual observed lunar position rather than the 
average position.)
   19
  Calculations indicate that the Easter of 1836 was also calendrically best on the Judean observational lunisolar calendar.
   20
 
In
 summary, a period of 1,803 years (658,532 days) is simultaneously two 
realignment intervals: (1) for the day, week, month, and year of the 
Jewish calendar; and (2) for the saros and the year. It seems impressive
 enough to merit a special name;
   21
  perhaps it could be called a “saros century,” being 100 saros periods.
Now consider some possible reasons for such astronomical precision in the timing of Elijah’s return.
Possible Significance
The
 evidence presented above suggests that the timing of Elijah’s return 
may have been arranged to occur on the best anniversary of Easter, 
calendrically speaking, in history. But for what reason?
The Lord’s possible intent in such a matter may be beyond our understanding (see Isa. 55:8–9);
 on the other hand, the scriptures are given to us to search for 
understanding, and in that spirit it may be acceptable to offer the 
following four possibilities.
1. Timing of the Last Dispensation. This
 is the dispensation of the fulness of times. When did it begin? At the 
First Vision? At the organization of the Church? One clue to answering 
this question was provided by the Prophet Joseph Smith, who taught that 
the sealing power of Elijah has been given in every true dispensation of
 the gospel (D&C 128:9),
 and that it “is necessary in the ushering in of the dispensation of the
 fulness of times, which is now beginning to usher in.” (D&C 128:18.)
Thus,
 apparently this dispensation could not have fully begun before 3 April 
1836, when the keys of Elijah were restored. But by July 1837 the 
dispensation apparently was in progress, when the Lord called it “the 
dispensation of the fulness of times” and referred to “the keys of the 
dispensation” which had been restored. (D&C 112:30–32.)
 Finally, Elijah’s own declaration seems to favor the significance of 
the 3 April 1836 date, for it was then that he declared, “The keys of 
this dispensation are committed into your hands.” (D&C 110:16.)
But
 why would the bestowal of the keys of the dispensation of the fulness 
of times have been timed to coincide with a special anniversary of the 
Resurrection? One possible reason is that one use of the phrase “fulness
 of time” referred to the time when the law of Moses would be fulfilled.
 Lehi prophesied that “in the fulness of time he [the Redeemer] cometh 
to bring salvation unto men.” (2 Ne. 2:3.)
 Paul clarified the meaning: “When the fulness of time was come, God 
sent forth his Son to redeem them that were under the law.” (Gal. 4:4–5.)
 Thus, the “fulness of time” apparently referred to the time that man 
would be redeemed, which was completed at the resurrection of the 
Redeemer.
At his return, Elijah stated that “the time has fully come” for Malachi’s prophecy to be fulfilled (D&C 110:14), suggesting that the prophecy of Elijah’s return was to be fulfilled at a specified time. Perhaps he also implied that the time had fully come to begin the fulness of times.
Thus,
 on Sunday, 3 April 1836, apparently the time had fully come to open the
 dispensation of the fulness of times on a special anniversary of the 
fulness of time of the Resurrection.
2. Timing of the “Elijah Period.” As
 discussed earlier, the Prophet Joseph Smith taught that “the spirit of 
Elias is first, Elijah second, and Messiah last.” This teaching suggests
 three distinct periods in Church history.
Perhaps
 3 April 1836 can be thought of as the close of the “Elias period” or 
preparatory phase of Church history, when finally all the forerunners 
had restored their keys in the spirit of Elias. (See D&C 27:5–13; D&C 128:20–21.)
 This period could have been closed when Elias himself, perhaps the same
 Elias who holds the keys of the restoration of all things (D&C 27:6), returned immediately before Elijah.
Then
 the next period could have commenced with the long-awaited advent of 
Elijah’s return. The Church would then enter into an era of temple work 
and building up the kingdom, having had all of the preparatory keys 
restored. The “Elijah period” would then end with the coming of the 
great day of the Lord.
3. Restoration of the Temple. The Lord used the symbolism of comparing his body to the temple. (John 2:21.)
 It seems very fitting that the restoration of the power and glory of 
the temple should occur on such a noteworthy anniversary of the 
restoration of the body of the Savior to power and glory. Note that the 
words resurrection and restoration are used interchangeably in the Book of Mormon (as in Alma 40–41), which is not surprising because resurrection is a type of restoration.
Further,
 one can note the calendrical similarity of the events of the week prior
 to April 3, according to the chronology presented in Part 1. On Sunday,
 27 March A.D. 33, the body of Jesus was anointed (“dedicated”?) for burial. (John 12:1–7.) Similarly, the Kirtland Temple was dedicated on Sunday, 27 March 1836. (D&C 109.)
 Moreover, during the week following both of these dedications, the 
ordinance of the washing of feet was introduced and the sacrament of the
 Lord’s supper was observed. (See History of the Church, 2:410–40.)
4. Body of the Church Restored.
 The Lord’s church has also been compared to his physical body. After 
discussing the interdependence of various members of the physical body, 
Paul concluded, “Now ye are the body of Christ,” and explained that all 
positions in the Church are important. (1 Cor. 12:12–31.)
The
 organization of the Lord’s church in the latter days occurred on 6 
April 1830. Apparently, this “birth” of the ecclesiastical “body of 
Christ” occurred on the anniversary of the birth of his physical body, 6
 April 1 B.C. Thus, a correspondence is suggested between the birth of the Savior and the birth of his church.
It is proposed that on Easter Sunday, 16 Nisan, 3 April A.D. 33, the physical body of Christ was restored, clothed with a fulness of power and glory. (See Alma 40:23.) On Easter Sunday, 16 Nisan, 3 April A.D.
 1836, the ecclesiastical body of Christ was restored, clothed with a 
fulness of priesthood authority. Thus, a correspondence is suggested 
between the restoration of the body of the Savior to a fulness of power and the restoration of the body of the Church to the fulness of the Melchizedek Priesthood.
This
 article has attempted to show that the dates of the principal events in
 the Savior’s life and the date of Elijah’s return in this last 
dispensation are remarkably rich in significance. The restoration of the
 keys of this dispensation was an extremely important event which 
occurred on a very special anniversary of the proposed resurrection date
 for our Lord and Savior, Jesus Christ.
 On Easter, may we not only remember the restoration of the Savior’s 
physical body, but also the restoration of the fulness of the priesthood
 to the body of his church.
Realignment Intervals
To
 understand the concept of a “realignment interval,” consider a 
wristwatch. (Figure 1.) It has a second hand, a minute hand, and an hour
 hand to keep track of three different time intervals. The starting 
point of the day occurs when all three hands point exactly straight up. A
 realignment interval for the watch is completed when all three hands 
again point straight up, that is, after exactly twelve hours.
Realigning
 the hands of a watch is simple because there are an exact number of 
seconds in a minute and an exact number of minutes in an hour. Thus, the
 first realignment interval encountered is a perfect lineup, and there 
is no reason to search for more accurate intervals.
     
      Figure 1. The interval of time necessary for all three hands on
 the wristwatch to turn around to the straight up position is an example
 of a “realignment interval.”
     
A
 calendar can be thought of as a clock that keeps track of longer 
periods or cycles of time—the sun and moon are like the hands of the 
clock. Note that our word “watch” (meaning clock) is the same as that 
formerly used to describe a time period determined by “watching” the sky
 (as in Matt. 24:43).
 A problem that arises is that sometimes the cycles do not “come out 
even.” For instance, the solar year, in which the seasons repeat, equals
 365.2422 days rather than a whole number of days such as 365. A 
question fundamental in the construction of any calendar is how to align
 the different cycles. The solution lies in finding an interval that is approximately a whole number of all the cycles.
The
 problem can be represented by the device drawn in Figure 2a. The large 
pulley has a circumference equal to 365.2422 times that of the smaller 
one. If each one has an arrow painted on it that points exactly 
vertical, after how many revolutions will both arrows be pointing 
straight up again?
Because the circumference is an irrational number of days, as is the case with most astronomical periods, the two pointers never again point straight up exactly simultaneously. There are only approximate solutions; the longer one is willing to wait, the more accurately they will align.
For
 example, after 365 revolutions of the small wheel, the larger one 
almost (but not quite) finishes a rotation, so a first approximation to a
 year is 365 days. But after 1,461 revolutions of the small pulley, one 
might notice that the large one has more nearly completed
 exactly four turns (years). That gives an average year of 1,461 divided
 by 4 = 365.25 days, which is the reason we add a leap day every 4 
years. Our Gregorian calendar is based on the observation that 146,097 
days very nearly equal 400 years, giving an approximate year of 146,097 
divided by 400 = 365.2425 days.

Figure
 2. The problem of aligning different calendrical periods is analogous 
to aligning arrows on pulleys of different circumferences. (A) Our 
Gregorian calendar attempts to align the day (earth’s rotation) with the
 solar year (seasons). (B) The lunisolar calendar adds the complication 
of including the lunar month (moon’s phases). (C) The interval from the 
proposed Resurrection date to Elijah’s return realigned a calendar that 
also includes the week (7 days).
A realignment interval for the set of pulleys is a
 number of turns of the smallest one which brings all of the arrows back
 to the vertical point better than any smaller number of turns.
The
 seemingly simple problem of finding a realignment interval for several 
cycles is, in fact, a very difficult problem in number theory;
   *
  fortunately, however, it is easily solved with a computer by 
“brute force”—by simply checking every possible combination of numbers 
for the best fit.
For
 our solar calendar, 4 years is a realignment interval, whereas 400 
years is not because there is at least one better solution with a 
smaller number of years (12,053 days divided by 33 years = 365.2424 
days).
Figure
 2b depicts the more complex problem of realigning the lunisolar 
calendar, which also includes the lunar month, the period of the moon’s 
phases. The modern Hebrew calendar employs a realignment interval, 
called the Metonic cycle, that has been known since at least five 
centuries before Christ: 19 years very nearly equal 235 lunar months. 
This means that the lunisolar calendar requires leap months as well as 
leap days.
Figure
 2c represents the problem of realigning the Jewish calendar described 
in the text, also including the week as a cycle. The realignment 
intervals include 68, 152, 220, and 372 years. For example, in this 
century Easter falls on 3 April, 16 Nisan (Jewish) in the years 1904 and
 1988, being 68 and 152 years after 1836, respectively. For longer 
realignment intervals, the variable lengths of the year and day must be 
considered. The realignment interval of 1,803 years discussed in the 
text is better than any other until 5,382 years have elapsed.
The Saros
Perhaps
 the greatest contribution to astronomy from ancient Chaldea was the 
discovery of a period of 6,585 days (18.03 years) called the saros, after which eclipses might repeat.
   **
 
An
 eclipse occurs when the sun, moon, and earth form a straight line. 
Solar eclipses occur at a new moon, when the earth is in the moon’s 
shadow; lunar eclipses are at full moon, when the moon passes into the 
earth’s shadow. (See Figure 1.)

Figure
 1. A solar eclipse can occur at a new moon, or a lunar eclipse at a 
full moon, when the sun, earth, and moon are approximately in a straight
 line. The reddening of a lunar eclipse is caused by light being 
refracted into the earth’s shadow by the atmosphere. Note that a total 
solar eclipse is only visible to the small area of the earth in the 
center of the new moon’s shadow, whereas a total lunar eclipse can be 
visible to the entire night-time half of the earth.
For a given series of eclipses to reoccur, three conditions need to be fulfilled:
1.
 The phase (full or new) of the moon must be the same, which is why 
similar eclipses are always separated by a whole number of lunar months 
of 29.53059 days.
2.
 The moon must be near the place where its path crosses the sun’s 
apparent path. The period of such crossings is 27.21222 days.
3.
 The moon needs to be at about the same distance from the earth in order
 to completely cover the sun in total solar eclipses. (The moon’s 
distance from the earth changes because its orbit is not circular, which
 makes its apparent size vary by about 10 percent.) This reoccurs in 
intervals of 27.55455 days.
Thus,
 the problem of predicting when eclipses will repeat is a question of 
finding a realignment interval for those three cycles. (See Figure 2.) 
After an eclipse, when will all three cycles again coincide? One of the 
very best realignment intervals is the saros of 6,585.32 days.

Figure
 2. The saros (18.03 years) is a realignment interval after which 
eclipses may repeat. It realigns the periods in which the moon is at the
 same phase (such as new or full), at the same distance, and at the 
point of intersection of the moon’s orbit with the sun’s apparent path. 
Eclipse cycles can only reoccur when the sun, moon, and earth are once 
more in proper alignment—illustrated here by all three arrows pointing 
nearly straight up again.
As discussed in the text, the return of Elijah occurred 100 saros periods after the proposed date of the Savior’s resurrection.
