Chapter 5 — Part I — Article III (Of the Incarnation)
Section 191. Q. What is there further to be remarked of the birth of Jesus Christ from the Most Holy Mother of God? A. This: that since this birth was perfectly holy and void of sin, it was also without pain; for it was among the penalties of sin that God ordained Eve in sorrows to bring forth children. (J. Damasc. Theol. lib. iv. cap. 14, 6.)
