You are right to doubt it; it's a lie.
One explanation of where this urban legend came from, that I've heard, is that a bishop once spoke at a council claiming that "qui propter nos homines" in the Creed meant that Jesus became incarnate only to save men, not women. (This is a misunderstanding of "homines," which is "men" in the sense of "human beings" not not "men" in the sense of "male humans," which in Latin is "viri".)
The bishop was laughed at or shouted down (depending on which version of the story is told), and that was that.
Thanks for the reply. I don’t have the transcripts of all church councils so they can be searched, but it just didn’t sound write.
And then there’s that unfortunate quotation from Paul about how in heaven male and female will be no more. Which would really put a crimp in the Muslim version of heaven.
