So then, to return, there is no other reason for this, than that “love has waxed cold;” and the cause again why love has waxed cold, is that “iniquity abounds.” For this leads to selfishness, and divides and severs the body, and relaxes it and rends it to pieces. But where virtue is, it does the reverse. Because the man that is virtuous is also above money; so that were there ten thousand such in poverty they would still be peaceable; while the covetous, where there are but two, can never be at peace. Thus then if we are virtuous, love will not perish, for virtue springs from love, and love from virtue. And how this is, I will tell you. The virtuous man does not value money above friendship, nor does he remember injuries, nor does wrong to his neighbor; he is not insolent, he endures all things nobly. Of these things love consists. Again, he who loves submits to all these things, and thus do they reciprocally produce one another. And this indeed, that love springs from virtue, appears from hence, because our Lord when He says, “because iniquity shall be multiplied, the love of the many shall wax cold,” plainly tells us this. And that virtue springs from love, Paul tells us, saying, “He that loves his neighbor has fulfilled the law.” So then a man must be one of the two, either very affectionate and much beloved, or else very virtuous; for he who has the one, of necessity possesses the other; and, on the contrary, he who knows not how to love, will therefore commit many evil actions; and he who commits evil actions, knows not what it is to love.
Moral. Let us therefore follow after charity; it is a safeguard which will not allow us to suffer any evil. Let us bind ourselves together. Let there be no deceit among us, no hollowness. For where friendship is, there nothing of the sort is found. This too another certain wise man tells us. “Though you drew a sword at your friend, yet despair not: for there may be a returning again to favor. If you have opened your mouth against your friend, fear not; for there may be a reconciliation: except for upbraiding, or disclosing of secrets, or a treacherous wound: for for these things a friend will depart.” For “disclosing,” says he, “of secrets.” Now if we be all friends, there is no need of secrets; for as no man has any secret with himself and cannot conceal anything from himself, so neither will he from his friends. Where then no secrets exist, separation arising from this is impossible. For no other reason have we secrets, than because we have not confidence in all men. So then it is the waxing cold of love, which has produced secrets. For what secret have you? Do you desire to wrong your neighbor? Or, are you hindering him from sharing some benefit, and on this account concealest it? But, no, perhaps it is none of these things. What then, is it that you are ashamed? If so, then this is a token of want of confidence. Now then if there be love, there will be no “revealing of secrets,” neither any “upbraiding.” For who, tell me, would ever upbraid his own soul? And suppose even such a thing were done, it would be for some good; for we upbraid children, we know, when we desire to make them feel. And so Christ too on that occasion began to upbraid the cities, saying, “Woe unto you, Chorazin! Woe unto you, Bethsaida!” in order that He might deliver them from upbraidings. For nothing has such power to lay hold of the mind, or can more strongly arouse it, or brace it up when relaxed. Let us then never use upbraiding to one another merely for the sake of upbraiding. For what? Will you upbraid your friend on the score of money? Surely not, if at least you possess what you have in common. Will you then for his faults? No nor this, but you will rather in that case correct him. Or, as it goes on, “for a treacherous wound;” who in the world will kill himself, or who wound himself? No one.
Let us then “follow after love;” he says not simply let us love; but let us “follow after love.” There is need of much eagerness: she is soon out of sight, she is most rapid in her flight; so many things are there in life which injure her. If we follow her, she will not outstrip us and get away, but we shall speedily recover her. The love of God is that which united earth to Heaven. It was the love of God that seated man upon the kingly throne. It was the love of God that manifested God upon earth. It was the love of God that made the Lord a servant. It was the love of God that caused the Beloved to be delivered up for His enemies, the Son for them that hated Him, the Lord for His servants, God for men, the free for slaves. Nor did it stop here, but called us to yet greater things. Yes, not only did it release us from our former evils, but promised, moreover, to bestow upon us other much greater blessings. For these things then let us give thanks to God, and follow after every virtue; and before all things, let us with all strictness practice love, that we may be counted worthy to attain the promised blessings; through the grace and loving-kindness of our Lord Jesus Christ, with whom, to the Father together with the Holy Ghost, be glory, might, and honor, now and for ever and ever. Amen.
