Gregory of Elvira, on Song 3:4

“When I had a little passed by them, I found him whom my soul loveth: I held him: and I will not let him go, till I bring him into my mother’s house, and into the chamber of her that bore me.”

“"In my mother's house and in the chamber where she conceived me." This is the voice of the church speaking. If the church is a mother to all, we must ask for the identity of the mother of the church, in whose house and in whose chamber she is said to have been conceived. I have already shown above what is the church, namely, the body of Christ that consists of his gathering members. The mother of the church, therefore, is the holy heavenly Jerusalem.”
