Pseudo-Augustine
Catena Aurea · Matthäusevangelium 1
Then Joseph her husband, being a just man, and not willing to make her a public example, was minded to put her away privily.
(Serm. in App. s. 195.) Joseph, understanding that Mary was with child, is perplexed that it should be thus with her whom he had received from the temple of the Lord, and had not yet known,and resolved within himself, saying, What shall I do? Shall I proclaim it, or shall I overlook it? If I proclaim it, I am indeed not consenting to the adultery; but I am running into the guilt of cruelty, for by Moses’ law she must be stoned. If I overlook it, I am consenting to the crime, and take my portion with the adulterers. Since then it is an evil to overlook the thing, and worse to proclaim the adultery, I will put her away from being my wife.
