Hilary of Poitiers

He is wisdom itself not by His acts, but by His nature. Many indeed evade that saying of the Apostle’s, Christ is the wisdom and power of God, (1 Cor. 1:24) by saying, that truly in creating Him of a Virgin the Wisdom and Power of God were shewn mightily. (e.g. Paul of Samosata, &c.) Therefore that this might not be so explained, He calls Himself the Wisdom of God, shewing that it was verily He, and not the deeds relating to Him, of whom this was meant. For the power itself, and the effect of that power, are not the same thing; the efficient is known from the act.
