Gregory the Great — as excerpted in the Catena Aurea on Matthew 22:1-14

“(ubi sup.) G marriage feast for God the Son, when He joined Him to human nature in the womb of the Virgin. But far be it from us to conclude, that because marriage takes place between two separate persons, that therefore the person of our Redeemer was made up of two separate persons. We say indeed that He exists of two natures, and in two natures, but we hold it unlawful to believe that He was compounded of two persons. It is safer therefore to say, that the marriage feast was made by the King the Father for the King the Son when He joined to Him the Holy Church in the mystery of His incarnation. The womb of the Virgin Mother was the bride-chamber of this Bridegroom.”
