Happy Easter. Question. Who was the first Christian?

well, i dont think it was mary, nor john the baptist. the first christian was st.paul. mary, jesus himself, john the baptist, the apostles, all were jews and stayed in their jewish faith. the developed only a modified jewish religion, bit never had the idea to leave the jewish religion and make a new one. first paul was the one who created christianity. remember his struggle with peter about the question, if jesus was the salvation for only the jews or the whole world? so before paul it makes no sense to talk from christianity, christianity starts with paul, exactly in the moment as he fall from his horse on the way to damascus.

Well, I didnt see the movie, but my first thought would be John the babtist. He believed in Jesus before he started preaching Gods word. Of course maybe your right, Mary knew who Jesus was too.
