Catena Aurea · Lukasevangelium 1
Then said Mary unto the angel, How shall this be, seeing I know not a man? And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
(Lib. de Spirit. Sanct. c. v.) Hence also, St. Paul says, God sent forth his Son, born not (through a woman) but of a woman. For the words through a woman might convey only a notion of birth as a passing through, but when it is said, of a woman, (Gal. 4:4.) there is openly declared a communion of nature between the son and the parent.
