We know that we have passed from death unto life, because we love the brethren. He that loves not his brother abides in death.

We know that we have passed from death unto life. Not because we believe that we are predestinated, but as a moral certainty, by the testimony of a good conscience, by the innocency of our life, and the consolation of the Holy Spirit. S. John says this for their consolation and to keep them from dreading the hatred of the world. Be comforted by the thought, that by faith ye have been translated from the death of sin to a state of grace in this world, and in the world to come to glory, which will raise us above all hatred. And the clear proof of this is that we love the brethren. For this love is an undoubted sign and effect of sanctifying grace, and of the Holy Spirit Himself, from whom, as from an uncreated source, all love proceeds. S. Basil truly says, "When can a man be fully persuaded that God has remitted his sins? When he finds that his feelings are like his who said, "I have hated and abominated iniquity" ( Psalm 119:163)."
He gives here three signs of indwelling grace and righteousness. (1.) Hatred of sin; (2.) mortifying the flesh, and all evil desires; and (3.) zeal for the salvation of others, like S. Paul (2Cor. xi29). And S. Gregory (Dial. i1), "The mind which is filled with the Divine Spirit, furnishes its own proofs, viz, virtuous actions and humility. And if those perfectly co-exist in the same mind, it is clear that they witness to the presence of the Holy Spirit." And S. Leo (Serm. de Epiph. viii.) gives these three signs of grace and sanctity, humility, forgiveness of injuries, and doing as we would be done by. And "let every one who is such, doubt not that God rules and dwells within him."
He who loveth not (when he ought, or he who hates) abideth in death, with the stain of habitual sin, which abides after the act of sin is over; and from this he cannot escape, except by the grace of Christ, says Thomas Anglicus. But how the soul though immortal can yet die through sin, S. Augustine explains (de Civ. iii1), "The death of the soul takes place when God forsakes it, just as, the body dies when the soul leaves it. It is then the entire death of a Prayer of Manasseh , when the soul which has been forsaken of God, leaves the body, for in this case it does not itself live by God, nor does the body live through it." And in like manner S. Cyril Alex. says, "Death, properly speaking, is not that which separates body and soul, but that which separates the soul from God. God is life, and he who is cut off from Him, perishes."
Nay more, this death of the soul is absolutely termed death in our deeper teaching, for that death of the body which we dread so much is but a shadow and image of that true death, and not to be compared with it. See S. Gregory (Mor. iv17). And S. Augustine (de Civ. vi. cap. ult.), "If the soul lives in everlasting punishment, it should rather be called everlasting death, and not life." And S. Basil (Hom. v. on the Martyr Julitta) says, "Sin is the death of the soul, which would else be immortal. It deserves to be lamented with inconsolable grief," &c, And S. Jerome, on Isa. xiv. (Lib. vi.), terms a sinner "the devil"s carcase, for no one can doubt that sin is a most fœtid thing, when the sinner himself says, "My wounds stink and are corrupt.""
