Johannes Cocceius (1603-1669): Vivification of the new man is the cause of the mortification of the old man



There are two parts of conversion, answering to two ends. For the person who is converted is converted from bad to good, from darkness to light, from the slavery of Satan to God (1 Ki. 8:25; Is. 59:20; Jer. 15:19; Acts 26:18).

These parts are called in Scripture nekrosis, mortification, or ekdosis, the putting off of the old man; and zoopoiesis, vivification and endusis, the putting on of the new man. ‘Having put off the old man with his deeds; and having pit on the new man, which is renewed in knowledge after the image of him that created him’ (Col. 3:9-10, see also Eph. 4:22-24 and Gal. 5:24-25).

These parts go together. But, as regards the order of nature, although newness be subsequent to oldness, […] yet the newness of the love of God is the cause of abolishing the oldness of the enmity of God. Darkness is not removed except by light; nor death except by life; nor poverty except by riches; nor nakedness except by being clothed; nor ugliness except by beauty; nor vice except by virtue; in the same way, neither is hate except by love.

Johannes Cocceius (1603-1669) on the perspicuity of Scripture as a short cut to the truth


“Not only does Holy Scripture possess in itself such perspicuity that by it a man may be saved even though destitute of other instrument and aid. But also by His grace God brings it to pass, that interpretation of Scripture and manifestation of the truth arises from it. So there is no longer need to discover from the Scriptures truth unusual as it were, and unheard of (as we are forced to look for the meanings of the Jews from the Talmud and its exegetes, for those of the Turks from the Qur’an, the stone-dead opinions of other races from the tomes of the ancients). By propagating the Church once gathered by the prophets, Christ and the apostles to the end of the World, and by preserving the truth in it so that it does not depart from her mouth, Is. 59.21 , God brings it about that the gospel is preached in the world till the end of the world, and that it is put in everyone’s way together with the sacred literature itself, and that it is a short cut to learn and approve the truth from it.”
