The Epistles of Pope Fabian on the Golden Rule

”[...]as you read in the Acts of the Apostles, “There was at that time among them that believed one heart and one soul; neither said any of them that ought of the things which he possessed was his own; but they had all things common.” For there was no laying of accusations against each other among them, except what was friendly; neither ought there ever to be such among their followers or among believers: for the Lord says, “Do not that to another which thou wouldst not have done to thyself.” And He says also, “Thou shalt love thy neighbour as thyself;” and,” Love worketh no ill to his neighbour.”” (The Epistles of Pope Fabian, Second epistle §2)
