For as there are two covenants which God willed to make with men—the one legal and the other of grace—so also there is a twofold righteousness—legal and evangelical. Accordingly there is also a double justification or a double method of standing before God in judgment—legal and evangelical. The former consists in one’s own obedience or a perfect conformity with the law, which is in him who is to be justified; the latter in another’s obedience or a perfect observance of the law, which is rendered by a surety in the place of him who is to be justified—the former in us, the latter in Christ.
