Was the star the wise men followed really a star? Did it actually move so that they could follow it? The star is a stumbling block for a friend of mine.
Was the star a star like the sun? Well, not exactly, because stars are enormous, and being that close to the earth would have fried everything! Luke 2:9 says the glory of the Lord shone around the angels when they appeared to shepherds. Was THAT the light that was originally seen by the magi? Note that the passage simply describes WHAT happened, not explain HOW it happened. I wasn’t there, so all I can do is read the description gathered from those who were!
