There is one God and one Christ, and one Church, and one chair founded on Peter by the word of the Lord. It is not possible to set up another altar or for there to be another priesthood besides that one altar and that one priesthood. Whoever has gathered elsewhere is scattering.
Since the baptismal rebirth takes place only with the one Bride of Christ, where could he be born who is not a son of the Church?
Baptism pertains to the Church alone.
