And so it was, that, while they were there, the days were accomplished that she should be delivered.

AD 444
The book of the sacred Gospels referring the genealogy to Joseph, who was descended from David’s house, has proved through him that the Virgin also was of the same tribe as David, inasmuch as the divine law commanded that marriages should be confined to those of the same tribe. And Paul, the interpreter of the heavenly doctrines, clearly declares the truth, bearing witness that the Lord arose out of Judah. The natures, however, which combined unto this real union were different, but from the two together is one God the Son, without the diversity of the natures being destroyed by the union. For a union of two natures was made, and therefore we confess one Christ, one Son, one Lord. And it is with this notion of a union that we proclaim the Virgin to be the mother of God, because God the Word was made flesh and became man, and by the act of conception united to himself the temple that he received from her. For we perceive that two natures, by an inseparable union, met together in him without confusion, and indivisibly. For the flesh is flesh and not deity, even though it became the flesh of God. In like manner also the Word is God and not flesh, though for the dispensation’s sake he made the flesh his own. But although the natures which came together to form the union are both different and unequal to one another, yet he who is formed from them both is only one. We may not separate the one Lord Jesus Christ into man and God, but we affirm that Christ Jesus is one and the same, acknowledging the distinction of the natures, and preserving them free from confusion with one another.
