The Church is officially silent on the issue of whether or not Mary suffered pain in childbirth, although some Fathers, Doctors, and theologians assume that her immaculate state rendered her free from it. Strictly speaking, we need not assume that Mary was free from labor pains. Christ too was sinless and went through hideous suffering on the cross. If Mary’s labor to bring Christ into the world was painful, just as is ordinary childbirth, it may have been so in order to allow her to be in greater conformity to the life of her Son, who also would suffer. Even so, it is also true that she could have been free from childbirth pain. Absent a ruling from the Church, we just don’t know for certain.
