The stigmata is sores or wounds in the places that Jesus suffered wounds during the crucifixion. That's about as much as I know.
What's the purpose of the stigmata?
Is the stigmata biblical? Similarly, if Jesus' crucifixion was payment for our sins, is the stigmata anti-biblical since we are taking on the suffering of Jesus (indicating that our sins are on ourselves and that his suffering wasn't sufficient)?
Also, How do we know that the stigmata is of Christian origin (meaning that we're reflecting Christ's crucifixion and not someone else that was crucified)?
