Context

“A popish priest once once argued with me in this manner: Evil works are damned, therefore good works justify. I answered: This your argument is nothing worth; it concludes not ratione contrariorum; the things are not in connection; evil works are evil in complete measure, because they proceed from a heart that is altogether spoiled and evil; but good works, yea, even in an upright Christian, are incompletely good; for they proceed out of a weak obedience but little recovered and restored. Whoso can say from his heart, I am a sinner, but God is righteous;” source
