Isaías 28

Isaías 28:16

The foundation of justice therefore is faith, for the hearts of the just dwell on faith. And the just man that accuses himself builds justice on faith, for his justice becomes plain when he confesses the truth. So the Lord says through Isaiah: "Behold, I lay a stone for a foundation in Zion." This means Christ as the foundation of the church. For Christ is the object of faith to all; but the church is as it were the outward form of justice; it is the common right of all. — On the Duties of the Clergy 1.29
