My dove, my perfect one, is the only one; she is the only one of her mother, she is the favorite one of her that bore her. The daughters saw her, and blessed her; yea, the queens and the concubines, and they praised her.
All Commentaries on Song of Songs 6:9 Go To Song of Songs 6
Bede
AD 735
“My dove, my perfect one, is one.” [The church] is one because it does not accept a schismatic division. It is one because it is not a collection of various parties, some before the law, some under the law, some under grace, some of the circumcision, and others of the uncircumcised. But just as “there is one Lord, one faith, one baptism, and one God and Father of everyone,” so also is there one Catholic multitude of all the elect throughout every place and every era of the world, subjected to one God and Father. This is why Luke teaches that [the church] should be called Catholic.
