Chapter 5 — Part I: The Creed — Article III: Who Was Conceived by the Holy Ghost, Born of the Virgin Mary
Section 2. "Who was Conceived," — The pastor, then, should enter on the exposition of this third Article by developing the grandeur of this mystery, which the Sacred Scriptures very frequently propose for our consideration as the principal source of our eternal salvation. Its meaning he should teach to be that we believe and confess that the same Jesus Christ, our only Lord, the Son of God, when He assumed human flesh for us in the womb of the Virgin, was not conceived like other men, from the seed of man, but in a manner transcending the order of nature, that is, by the power of the Holy Ghost; so that the same Person, remaining God as He was from eternity, became man, what He was not before.
