An Example of the Veneration of the Number Four in the Christian Tradition Before the Four Gospels Were Canonized

From the so-called Valentinian Exposition at Nag Hammadi:

I will speak my mystery to those who are mine and to those who will be mine. Moreover it is these who have known him who is, the Father, that is, the Root of the All, the Ineffable One who dwells in the Monad. He dwells alone in silence, and silence is tranquility since, after all, he was a Monad and no one was before him. He dwells in the Dyad and in the Pair, and his Pair is Silence. And he possessed the All dwelling within him. And as for Intention and Persistence, Love and Permanence, they are indeed unbegotten. God came forth: the Son, Mind of the All, that is, it is from the Root of the All that even his Thought stems, since he had this one (the Son) in Mind. For on behalf of the All, he received an alien Thought since there were nothing before him. From that place it is he who moved [...] a gushing spring. Now this is the Root of the All and Monad without any one before him. Now the second spring exists in silence and speaks with him alone. And the Fourth accordingly is he who restricted himself in the Fourth: while dwelling in the Three-hundred-sixtieth, he first brought himself (forth), and in the Second he revealed his will, and in the Fourth he spread himself out.
