Origen
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.
(non occ.) She was indeed espoused to Joseph, but not united in wedlock; that is to say, His mother immaculate, His mother incorrupt, His mother pure. His mother! Whose mother? The mother of God, of the Only-begotten, of the Lord, of the King, of the Maker of all things, and the Redeemer of all.
