"
Which prophecies would have been invalidated if Jesus had married?"Isaiah 53:8, "..and who shall declare His generation? for he was cut off out of the land of the living:"
and Dan 9:26 "...And after threescore and two weeks shall Messiah be cut off,..."
for starters.
I fail to see what those prophecies have to do with marriage. Mind you, I don't think He was married, but is rather betrothed to the Church.
