"Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness, meekness, long-suffering. And above all these, love, which is the bond of perfection. And let the peace of God reign in your hearts, to which also ye are called in one body; and be thankful," ye who, while still in the body, like the just men of old, enjoy impassibility and tranquillity of soul.
"Put on, therefore, as the elect of God, holy and beloved."
He shows the easiness of virtue, so that they might both possess it continually, and use it as the greatest ornament. The exhortation is accompanied also with praise, for then its force is greatest. For they had been before holy, but not elect; but now both "elect, and holy, and beloved."
"A heart of compassion." He said not "mercy," but with greater emphasis used the two words. And he said not, that it should be as towards brethren, but, as fathers towards children. For tell me not that he sinned, therefore he said "a heart." And he said not "compassion," lest he should place them in light estimation, but "a heart of compassion, kindness, humility, meekness, longsuffering."
[AD 215] Clement of Alexandria on Colossians 3:12
