Augustine of Hippo
Catena Aurea · Matthäusevangelium 1
But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
(Enchir. 38.) But shall we therefore say that the Holy Spirit is the Father of the man Christ, that as God the Father begot the Word, so the Holy Spirit begot the man? This is such an absurdity, that the ears of the faithful cannot bear it.
