64. Dost thou ask me how He is a Son, if He have not a Father existing before Him? I ask of thee, in turn, when, or how, thinkest thou that the Son was begotten. For me the knowledge of the mystery of His generation is more than I can attain to, Ps. cxxxix. 5.—the mind fails, the voice is dumb—ay, and not mine alone, but the angels’ also. It is above Powers, above Angels, above Cherubim, Seraphim, and all that has feeling and thought, for it is written: “The peace of Christ, which passeth all understanding.” Phil. iv. 7. The better-known version “The peace of God” is supported by stronger ms. authority. If the peace of Christ passes all understanding, how can so wondrous a generation but be above all understanding?
