124. Learn now that the Spirit too knows God the Father, for it is written that, “As no one knoweth the things of a man, save the spirit which is in him, so too the things of God no one knoweth save the Spirit of God.” “No one,” he says, “knoweth save the Spirit of God.” 1 Cor. ii. 11. Is, then, the Son of God excluded? Certainly not, since neither is the Spirit excluded, when it is said: “And none knoweth the Father, save the Son.”
