COMPREHENDING ONE God that has TWO physical bodies: now THAT takes some doing!!
Try imagining God the Father speaking from Heaven, Christ in the river Jordan being baptised, and the Holy Spirit descending like a dove. The Bible seems to be going out of the way to describe three different entities. But if you want to call that one, at least allow others to see it differently without condemning them and calling them non-Christian.
