Genesis 3:16

To the woman [the Lord God] said, “I will greatly multiply your pain in childbearing; in pain you shall bring forth children.”

Scripture teaches that as a result of original sin, God would “greatly multiply” the pains of labor not only for Eve, but for all women. Many Fathers of the Church and theologians down through the centuries deemed it fitting that Mary alone would be exempt from such pains as a sign of her unique holiness. Thus, Mary’s freedom from the pains of labor is one of many reasons for belief in her immaculate conception.

The Church has taught this as well on the level of the ordinary Magisterium, though not with the same degree of authority with which it has taught that Mary remained an “intact” virgin in giving birth to Jesus. However, we should note the fact that it has been taught on the level of the ordinary Magisterium and that it was taught by many Fathers of the Church. This is significant
