then google it.
I did. It talks about Gen 3:15 which says “He shall crush your head” and doesn’t say anything about Mary. I was wondering if there was a more obscure reference in Revelation. I did read on where it said that the original Hebrew and Greek also say “He” but the Latin Vulgate said “She” and that the RCC decided to stick with that.
So, thanks for insulting me and then forcing me to look it up so I learned the whole story when I was going to be content to just hear the RC version!
