A new commandment I give unto you, That you love one another; as I have loved you, that you also love one another.
Read Chapter 13
Augustine of Hippo
AD 430
1. The Lord Jesus declares that He is giving His disciples a new commandment, that they should love one another. A new commandment, He says, I give unto you, that you love one another. But was not this already commanded in the ancient law of God, where it is written, You shall love your neighbor as yourself? Leviticus 19:18 Why, then, is it called a new one by the Lord, when it is proved to be so old? Is it on this account a new commandment, because He has divested us of the old, and clothed us with the new man? For it is not indeed every kind of love that renews him that listens to it, or rather yields it obedience, but that love regarding which the Lord, in order to distinguish it from all carnal affection, added, as I have loved you. For husbands and wives love one another, and parents and children, and all other human relationships that bind men together: to say nothing of the blame-worthy and damnable love which is mutually felt by adulterers and adulteresses, by fornicators and p...
A new commandment I give to you; that you love one another. Why new? Various reasons are given. S. Augustine says, because the faithful, by love put off the old man and put on the new. "New," says Jansenius, "that is renewed by Christ, having grown out of date in the minds of men." Maldonatus says that "new" means excellent, surpassing. As in Rev. vii, the virgins are said to sing "a new Song of Solomon ," that is a remarkable one.
But I say that the command of love is called new, because it is the chief characteristic of the New Testament, and specially commended by the words and example of Christ; just as, on the other hand, the command of fear was the old command and the chief one among the Jews. The new law is that of love, as the old was of fear.
Secondly, because Christ here taught us this precept of love more explicitly, and more forcibly than it had been taught before; and for this cause He sent forth the Holy Spirit at Pentecost, that we might fulfil this new commandment of ...
Well and truly writes the inspired Paul: Wherefore if any man is in Christ, he is a new creature: the old things are passed away; behold all things are become new. For Christ does renew us, and fashions us again to a newness of life which is unknown to and untravelled by the rest of mankind, who love to regulate their lives by the Law, and remain constant to the precepts given by Moses. For the Law makes nothing perfect, as it is written; but it is very evident that the standard of reverence towards God involved in the commands of our Saviour is the highest possible. For this is why He Himself somewhere says to us: Verily, verily, I say unto you, Except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no wise enter into the kingdom of heaven. We do not wish to struggle against the manner of life of the Jews, and yet except we outstrip very decisively the righteousness contained in the Law, I doubt if we should ever enter into the kingdom of he...
The commandment of mutual love had been previously given, but evidently misconstrued and abridged by the Jews to friends only, to this life only, and for earthly respects: but Jesus Christ reneweth it and enlargeth it after the form of his own love towards us, and giveth grace to observe it. (Bristow)
