In farther illustration of the subject, let us consider what kind of righteousness man can have, during the whole course of his life, and for this purpose let us make a fourfold division. Mankind, either endued with no knowledge of God, are sunk in idolatry; or, initiated in the sacraments, but by the impurity of their lives denying him whom they confess with their mouths, are Christians in name only; or they are hypocrites, who with empty glosses hide the iniquity of the heart; or they are regenerated by the Spirit of God, and aspire to true holiness. In the first place, when men are judged by their natural endowments, not a iota of good will be found from the crown of the head to the sole of the foot, unless we are to charge Scripture with falsehood, when it describes all the sons of Adam by such terms as these: "The heart is deceitful above all things, and desperately wicked." "The imagination of man's heart is evil from his youth." "The Lord knoweth the thoughts of man that they are vanity." "They are all gone aside: they are altogether become filthy; there is none that does good, no, not one." In short, that they are flesh, under which name are comprehended all those works which are enumerated by Paul; adultery, fornication, uncleanness, lasciviousness idolatry witchcraft, hatred, variance, emulation, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and all kinds of pollution and abomination which it is possible to imagine. 422 Such, then, is the worth on which men are to plume themselves. But if any among them possess an integrity of manners which presents some semblance of sanctity among men, yet because we know that God regards not the outward appearance, we must penetrate to the very source of action, if we would see how far works avail for righteousness. We must, I say, look within, and see from what affection of the heart these works proceed. This is a very wide field of discussion, but as the matter may be explained in few words, I will use as much brevity as I can.
