Pseudo-Augustine, on Matt 1:18

“Now the generation of Christ was in this wise. When as his mother Mary was espoused to Joseph, before they came together, she was found with child, of the Holy Ghost.”

“(in App. 122 et al.) Christ was also born of a pure virgin, because it was not holy that virtue should be born of pleasure, chastity of self-indulgence, incorruption of corruption. Nor could He come from heaven but after some new manner, who came to destroy the ancient empire of death. Therefore she received the crown of virginity who bare the King of chastity. Farther, our Lord sought out for Himself a virgin abode, wherein to be received, that He might shew us that God ought to be borne in a chaste body. Therefore He that wrote on tables of stone without an iron pen, the same wrought in Mary by the Holy Spirit; She was found with child of the Holy Ghost.”
