“Since there are so many clear testimonies, we should not seek from others for the truth which can easily be received from the Church. It was there, in the Church, that the Apostles, like a rich man making a deposit, fully bestowed everything that belongs to the truth. She is the entrance to life; all others are thieves and robbers. Therefore we ought to avoid them, but to love with the greatest love the things of the Church, and so lay hold of the tradition of the truth.”
(St. Irenaeus of Lyons, writings against the gnostics)
