Mortification and Vivication

Calvin, in the Institutes, on what occurs in a man who realizes that he has sinned against God, 3.3.3:

But certain men well versed in penance, even long before these times, meaning to speak simply and sincerely according to the rule of Scripture, said that it consists of two parts: mortification and vivification. "Mortification" they explain as sorrow of soul and dread conceived from the recognition of sin and the awareness of divine judgment. For when anyone has been brought into a true knowledge of sin, he then begins truly to hate and abhor sin; then he is heartily displeased with himself, he confesses himself miserable and lost and wishes to be another man. Furthermore, when he is touched by any sense of the judgment of God (for the one straightway follows the other) he then lies stricken and overthrown; humbled and cast down he trembles; he becomes discouraged and despairs. This is the first part of repentance, commonly called "contrition." "Vivification" they understand as the consolation that arises out of faith. That is, when a man is laid low by the consciousness of sin and stricken by the fear of God, and afterward looks to the goodness of God-to his mercy, grace, salvation, which is through Christ-he raises himself up, he takes heart, he recovers courage, and as it were, returns from death to life. 'Now these words, if only they have a right interpretation, express well enough the force of repentance; but when they understand vivification as the happiness that the mind receives after its perturbation and fear have been quieted, I do not agree. It means, rather, the desire to live in a holy and devoted manner, a desire arising from rebirth; as if it were said that man dies to himself that he may begin to live to God.
