Apostolic Constitutions, Book II 13
1Yet it is very necessary that those who are yet innocent should continue so, and not make an experiment what sin is, that they may not have occasion for trouble, sorrow, and those lamentations which are in order to forgiveness. For how do you know, O man, when you sin, whether you shall live any number of days in this present state, that you may have time to repent? For the time of your departure out of this world is uncertain; and if you die in sin, there will remain no repentance for you; as God says by David, In the grave who will confess to You? It behooves us, therefore, to be ready in the doing of our duty, that so we may await our passage into another world without sorrow. Wherefore also the Divine Word exhorts, speaking to you by the wise Solomon, Prepare your works against your exit, and provide all beforehand in the field, lest some of the things necessary to your journey be wanting; as the oil of piety was deficient in the five foolish virgins mentioned in the Gospel, when they, on account of their having extinguished their lamps of divine knowledge, were shut out of the bride-chamber. Wherefore he who values the security of his soul will take care to be out of danger, by keeping free from sin, that so he may preserve the advantage of his former good works to himself. Therefore, so judge as executing judgment for God. For, as the Scripture says, the judgment is the Lord's. In the first place, therefore, condemn the guilty person with authority; afterwards try to bring him home with mercy and compassion, and readiness to receive him, promising him salvation if he will change his course of life, and become a penitent; and when he does repent, and has submitted to his chastisement, receive him: remembering that our Lord has said, There is joy in heaven over one sinner that repents.
