Because all men be sinners and offenders against God, and breakers of His law and commandments, therefore can no man by His own acts, works, and deeds (seem they never so good) be justified, and made righteous before God: But every man of necessity is constrained to seek for another righteousness or justification, to be received at God’s own hands, that is to say, the forgiveness of his sins and trespasses, in such things as he hath offended. And this justification or righteousness, which we so receive of God’s mercy and Christ’s merits, embraced by faith, is taken, accepted, and allowed of God, for our perfect and full justification.
Thomas Cranmer
