Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 1
Now the birth of Jesus Christ was on this wise: When as His mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Having said above, And Jacob begat Joseph, to whom Mary being espoused bare Jesus; that none who heard should suppose that His birth was as that of any of the forementioned fathers, he cuts off the thread of his narrative, saying, But Christ’s generation was thus. As though he were to say, The generation of all these fathers was as I have related it; but Christ’s was not so, but as follows, His mother Mary being espoused.
