1 John 2:5

But whoso keepeth His word, in him verily is the love of God perfected. This confirms the previous statement, by way of antithesis. The word is spoken of in the singular number, because the law of love comprehends all others, just as a root implies the leaves and fruit, and the whole tree.

Perfect love is that which fulfils that command, "Thou shalt love the Lord thy God with all thy heart," &c. (Matthew 22:37.) For he who observes the commands of God loves God with all his heart, though he may sin venially, which is a necessary evil in this life of corruption. But in this perfectness of Christian charity and life there are various grades. The first is so to love God with all the heart as never to offend Him mortally. 2. Never deliberately to offend Him venially, even for the sake of the whole world. 3. To renounce, for the love of God, the love of every creature, and to devote thyself entirely to His service as "religious" do. See, too, Rom. viii. 35. 4. Not to think, wish, or love anything save God, or for His sake. Origen (Præf. in Evan. S. Joan) says, "He who is perfect, no longer lives himself, but Christ lives in him;" and S. Augustine (Serm. xxxix . de temp. [nunc cccl]) says, "As covetousness is the root of all evil, so is love the root of all good. The love of God and our neighbour fills up the whole length and breadth of the sacred word." He then adds, "Without it a rich man is poor, with it a poor man is rich. It gives patience in adversity, moderation in prosperity, endurance in hard sufferings, and so forth." And S. Bernard writes thus to the brethren (de Monte Dei, xix.): "Perfection, though not of the same kind, is required of you all. As one star differs from another star in glory, so does cell from cell, in the beginners, the progressing, and the perfect The first state may be called the animal, the next the rational, the last the spiritual, the first relating to the body, the second to the soul, the third finding its rest in God alone. Each, however, has its own rate of progress and measure of perfection. The beginning consists in perfect obedience in the animal life, its progress in bringing the body into subjection, its perfection in turning the practice of good into delight in it. And so too, in the rational life, the perfection of which is the spiritual life, and the perfection of the spiritual life is to be changed into the same image from glory to glory, as by the Spirit of the Lord." And S. Maximus says (De Charitate Cent. iii. 97), "That soul is perfect whose whole powers turn only towards God." See also Centur. iv. 17; and S. Francis (in 0pusc. decem perfect considered to be spurious: see Cave) says, "A Christian's perfection is to root out from his heart all worldly affections, and to find no root, or resting-place, save in Him who made it. And again, to have such patience as to love him the more who has done or said any wrong of him. For as God of His bounty conferred on him all his blessings, so should he believe that He secretly pledges Himself to send on him every kind of evil, in order to show a sinner his sins, and thus lightly punish them once in this present life, that He may not scourge them more severely for ever. He should therefore love him who has done or spoken any evil against him, as being the messenger of God to him for good," &c.

Hereby know we that we are in Him. S. Augustine here adds, ' If we be perfected in Him,' but nearly all MSS. omit these words. The meaning is, we know that we are in Him if we keep His commandments. This is the effect and sign of our cleaving to Him. Moreover, it is by love that we abide in God, as the thing loved is in the lover. For the soul is more in that which it loves, than in that which it animates. And God in return loves those who love Him, dwells in them, cares for, directs and protects them. Augustine says, that we who love Christ are in Christ, as the members in the body. See John 15:23. The soul then of one who loves God is a kind of temple, in which all the three Persons abide. And by abiding S. John means intimate union, permanent resting, continual presence, friendly converse, and all other offices of true friendship.
