Augustine of Hippo
Catena Aurea · Johannesevangelium 13
Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you. A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.
(Tr. lxv. 3) if He said, Other gifts are shared with you by those who are not mine; birth, life, sense, reason, and such good things as belong alike to man and brutes; nay, and tongues, sacraments, prophecy, knowledge, faith, bestowing of goods upon the poor, giving the body to be burned: but forasmuch as they have not charity, they are tinkling cymbals, they are nothing: nothing profits them.
