There is a recipe for abortion in the Bible! (Numbers 5:11-31) Which makes it odd that so many biblical literalists are opposed. Jesus never said a word about it, and nobody thought up ensoulment at conception until 1500 years after Jesus. Before that, it was thought the soul enters the body with the first breath. Actually, infant mortality was so high around Jesus' times infants under a year old were not even counted in the census.
So one could make the argument that opposing abortion is heresy. But that's not at all unusual. Lots of things modern "Christians" believe are heretical. Fundamental things like "Your dead Grandpa is in heaven watching over you." flys in the face of early Christian beliefs that said people take a long dirt nap until Jesus returns, and only saints go right to heaven. In general, Christian dogma has gotten a lot more comforting, and less Christian over the centuries. Now we have so-called Christians saying immigration laws are more important than "Love your neighbor as yourself." Exactly the opposite of what Jesus is quoted as saying.
