"Christ laid down one definite system of truth which the world must believe without qualification, and which we must seek precisely in order to believe it when we find it. Now you cannot search indefinitely for a single truth. You must seek it until you find, and when you find, you must believe. Then you have simply to keep what you have come to believe, since you also believe that there is nothing else to believe, and therefore nothing else to seek, once you have found and believe what He taught who bids you seek nothing beyond what He taught."

Tertullian, Apology
