There is more than one connection between the Egyptians and Christianity.

“Osiris’s coming was announced by Three Wise Men: the three stars Mintaka, Anilam, and Alnitak in the belt of Orion, which point directly to Osiris’s star in the east, Sirius (Sothis), significator of his birth.”
One must envision that the Virgo was rising in the East at the same time Sirus was visible in the east as well. But also Orion, called “The Three Kings” by oriental astronomers, was in proximity to these other two constellations.
Virgo is called Spica; it is to be found in the “ear of corn” (sign of fertility) which the Virgin holds.
Much has been made of the Matthew gospel account of the “star in the east” followed by “wise men” from afar, claimed to have heralded the birth of the newborn savior of the world.
And many ancient gods, kings and heroes were said to have been born under a ‘bright star’ or some other sort of celestial sign.In the gospel story, Jesus’s birth is signaled by a bright star and a visit from wise men or magi, as they are termed in the New Testament, representing Persian astrologers following the star.
Despite the stellar brilliance and obviousness, this tracking was apparently not a simple act, since these “wise men” are depicted as nevertheless illogically becoming hopelessly lost and must ask Christ’s enemy King Herod for assistance. (Mt 2:1-10) “It may be inferred from Mt 2 10 that in some way or other the wise men had for a time lost sight of the star. (Mt 2:10 states: “When they saw the star, they rejoiced exceedingly with great joy.”)
Although in the gospels these magi are not numbered, their gifts are counted as three. Hence, the familiar understanding is that Jesus’s birth was accompanied by a “star in the east” and “three wise men.” At a certain point the “three kings” were given names, Caspar, Melchior and Balthasar.
Coincidentally, there happen to be three very conspicuous stars in the “belt” of the constellation of Orion that are also called the “Three Kings.” Moreover, as French philosopher Simone Weil (1909-1943), herself a Christian, remarked, “The Christians named the three stars of Orion the Magi,” revealing esoteric knowledge of Christian astrotheology, regardless of when it was first adopted.
Within the constellation of Orion, “the Hunter,” are three bright stars said to make up his “belt.” Concerning these stars, in The Geography of the Heavens the astronomer Elijah Hinsdale Burritt remarks:They are sometimes denominated the Three Kings, because they point out the Hyades and Pleiades on one side, and Sirius, or the Dog-star, on the other. In Job they are called the Bands of Orion…
The biblical Book of Job (38:32) also contains reference to the Mazzaroth, or “zodiac,” and demonstrates significant astronomical knowledge, an important fact in consideration of the contention that, centuries later, the Jewish priesthood rehashed the Egyptian astrotheology in its “midrashic” or fictitious account of Jesus Christ.
The three highly visible “king-stars” of the splendid constellation of Orion are named Mintaka, Aniltak and Anilam or Alnilam, the latter of which means “string of pearls,” while the former two signify “belt.”
The statement in the Egyptian texts that Sothis “leads Orion” thus constitutes the motif of the bright star followed by these three “kings,” which have also been called the “three kings of the soothsayers,” a title that may indicate the antiquity of this royal appellation.
The bright star Sirius rose with the sun at the summer solstice, signaling the birth of Osiris as the Nile inundation and the birth of Horus as the daily solar orb. In winter, the Three Kings in the belt of Orion pointed to Sirius at night before the annual birth of the sun, which is also Horus.
The appearance of the three stars in a line with Sirius occurred in the night sky over Egypt thousands of years ago, pointing to the horizon as the new sun was born at the winter solstice.
Thus, it could be asserted that the three kings trailing the bright star announced the [re]birth of the savior (the Sun of God) at the winter solstice in Egypt, ages prior to the same event purportedly taking place in Judea.
