What was the star of Bethlehem — the Christmas star?
What was the star that led the wise men to Christ?
What was the star of Bethlehem — that amazing star that the Book of Matthew tells us the wise men followed so they could worship the new-born Jesus Christ as the King of the Jews?
Theories have included Johannes Kepler's much-quoted proposal that the “star” was a conjunction of the planets Jupiter and Saturn in 7BC, to the way-out theory that it was a UFO. Unfortunately, it is easier to say what the star was not than what it was.
The aligned planets theory
This theory says that the Bethlehem star was a conjunction (alignment) of the planets Jupiter and Saturn, which occurred from May 29 to December 4 in the year 7BC.
There are several reasons why this explanation is wrong.
The meteor and comet theory
Could the star have been a meteor or a comet? The major problem here again is that neither of these would stand over a house. Meteors in particular disappear rapidly, so they wouldn't even be around at the start and finish of the wise men's journey.
The UFO theory
If the proponents of this theory mean spacecraft from other planets, what interest would extraterrestrials have in Christ's birth on earth? And why would the wise men so clearly tell Herod it was a star if it was an unidentified object in the sky?
In any case, genuine UFO encounters are usually associated with occultic or Satanic activity in an area. They don't lead people to Christ. (See our article Where do UFOs come from?)
The supernova theory
Some prominent Christians support this theory, but again, a supernova won't stand over a single house.
The Shekinah glory cloud or moving light theory
Some think the star could have been a cloud or light, like the pillar of fire that led the Israelites in the wilderness. But as Dr. Henry Morris pointed out, why would the Magi call this a star? “Surely,” he said, “they would know the difference between a stationary star up in the heavens, and a light moving along near the earth.” After all, they were known as the “wise men” — knowledgeable in the astronomy of the time — not naive simpletons.
Dr. Morris asked, “How could the Magi ever identify such a mysterious light as announcing the King of the Jews? And why would it not have led them directly to Bethlehem, instead of their having first to consult with the Jewish priests and scribes in Jerusalem?”
The angel theory
The idea that the star could have been an angel has some support, even if the support is not strong.
In Revelation 1:20 we are told the mystery of the seven stars — “The seven stars are the angels of the seven churches …” This seems to indicate that churches have the equivalent of guardian angels, and they are represented as stars.
It may be stretching the meaning too much to apply this to the star the wise men followed to Jerusalem, but certainly an angel sent from God could guide from the sky and also stand over a particular house. The problem is that the Revelation reference is a symbolic representation, whereas the Matthew reference seems to be literal.
The supernatural star theory
The supernatural star proposal is probably the one we are meant to follow. Having had to discard all the theories that try to explain the star as a natural celestial object, the most obvious explanation we are left with is that the star was a supernatural phenomenon created for the sole purpose of announcing the birth of Jesus Christ to those who were able to recognize it as such.
Skeptics and those who do not believe in miracles will find this hard to accept, but it will not trouble believing Christians.
This explanation makes sense when we realize that not everyone saw this star. Herod's chief priests and scribes had to work out from Scripture where Christ was born, which means they didn't see any star that could lead anyone anywhere.
As we said at the beginning, unfortunately it is easier to say what the star was not than what it was.
