These things I command you, that you love one another.

Cyril of Alexandria

For shall we not allow that the choosing out of those still faithless and astray to obedience to God is the work of the highest love of all? But this is undeniable. And Paul hastened to do this when he said: We are ambassadors therefore on behalf of Christ, as though God were entreating by us: we beseech you on behalf of Christ, be ye reconciled to God. So also does Peter, saying boldly to the Jews: And now, brethren, I wot that in ignorance ye did it, as did also your rulers. Repent ye therefore and be baptized every one of you in the name of our Lord Jesus Christ. You see then how and with what zeal they meet those who have not believed, and bring to them the word which they have not sought, not making it necessary for these in their ignorance to choose themselves as their teachers, but anticipating in this even him who has as yet been unwilling to learn any elementary truth.
But since our Saviour's words have this addition, that ye should go and bear fruit and that your fruit should abide, it is our duty to inquire what this means. For what is the meaning of the expression that the fruit of His disciples remains? I think then that by fruit which remains our Saviour means that produced by the training of the Gospel and not by the righteousness of the Law. For the latter has become obsolete by reason of its inability to accomplish anything. For the Law accomplished nothing, as Paul says; but the new righteousness burst as it were into blossom in its stead and lifted up its head, making obsolete and putting away the former, and bringing in the fruit that truly remains and is preserved. Thus speaks the inspired Paul addressing us, and saying that the righteousness by the Law was gladly and readily accounted by him as loss in order that he might gain Christ, that is, the righteousness and fruit-bearing of the Gospel by the faith that is in Him. For such fruit as this will continue and be perennial, being capable of fulfilling the soul of man with righteousness. For no other new instruction will steal in beside the messages of the Gospel making the former obsolete, as was undoubtedly the ease with the Mosaic command. But the Word of the Saviour will stand for ever, as indeed He Himself says: Heaven and earth shall pass away: but My words shall not pass away.
