Augustine of Hippo
Catena Aurea · Johannesevangelium 15
This is my commandment, That ye love one another, as I have loved you. Greater love hath no man than this, that a man lay down his life for his friends. Ye are my friends, if ye do whatsoever I command you. Henceforth I call you not servants; for the servant knoweth not what his Lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you. Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you. But I have called you friends, for all things that I have heard of My Father, I have made known unto you.
(Tract. lxxxvi. 3) Ineffable grace! For what were we before Christ had chosen us, but wicked, and lost? We did not believe in Him, so as to be chosen by Him: for had He chosen us believing, He would have chosen us choosing. This passage refutes the vain opinion of those who say that we were chosen before the foundation of the world, because God foreknew that we should be good, not that He Himself would make us good. For had He chosen us, because He foreknew that we should be good, He would have foreknown also that we should first choose Him, for without choosing Him we cannot be good; unless indeed he can be called good, who hath not chosen good. What then hath He chosen in them who are not good? Thou canst not say, I am chosen because I believed; for hadst thou believed in Him, thou hadst chosen Him. Nor canst thou say, Before I believed I did good works, and therefore was chosen. For what good work is there before faith? What is there for us to say then, but that we were wicked, and were chosen, that by the grace of the chosen we might become good?
