Christ our Wisdom, Righteousness, and Sanctification

Where it is said that Jesus Christ is given to us to be our redemption, [1 Cor. 1:30] St. Paul declares at the same time how it is done, namely because (he says) he is given us to be our wisdom, righteousness, and sanctification. And how for wisdom? In order that our whole mind may rest upon him and not wander from him on this side or that. Again, he is given us to be our righeousness, in order there should not be any spot or wrinkle in us when we appear before the face of our God, but that the blood of Jesus Christ should suffice us for the whole of our uprightness. Also he is given to us for our sanctification, in order that we should be renewed by his Holy Spirit. And whoever separates these things one from another intends to tear Jesus Christ in pieces as much as lies in him.
