And he was told, "Your mother and your brothers are standing outside, desiring to see you." But he said to them, "My mother and my brothers are those who hear the word of God and do it."

Luke 8:20-21

"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."

- St. Cyprian of Carthage
