Return of a stellar body...maybe....the return of the days of noah in which the righteous are saved from cateclysms... most probably as Jesus warned!
I have no problem with the notion that the Bible contains a fair amount of astrological information. What is forbidden, is what Herod did or tried to do. He tried to use a God-given sign to thwart the will of God. Seeing a sign and understanding what it’s prophetic meaning is, is not divination or fortunetelling. Otherwise, recognizing the impending fulfillment of any sort of prophecy would be divination or fortunetelling.
The position of the ‘stars’ were integral to the days set aside as God’s days, for the feasts of Israel. I, for one, believe the prophecies concerning Messiah are marked by the feats days.
