That's true but with a twist. Christianity is actually a weird hybrid of Abrahamic religion and pre-existing graeco-roman traditions, and is so in a rather complex way, i.e it's not just absorbing a couple of rites here and there, but it also has roots in hybridation with mystery cults like the mysteries of Eleusis and the cult of Dionysus. Good read: The Immortality Key, by Brian Murarescu. The reason I said "true" and not "false" is that the church was very successful at rebranding the whole spiel to the point where the memory of the link was utterly removed from the collective awareness and only through digging and analysis we can reconstruct the story (and even then many people will just find it quite unbelievable).
