Catena Aurea · Lukasevangelium 1
And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. For with God nothing shall be impossible. And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
(sup.) Through an ineffable sacrament of a holy conception and a birth inviolable, agreeable to the truth of each nature, the same virgin was both the handmaid and mother of the Lord.
