Clement of Alexandria, on 1Thess 4:9

“But as touching the charity of brotherhood, we have no need to write to you: for yourselves have learned of God to love one another.”

“Salvation, accordingly, is the following of Christ: "For that which is in Him is life." "Verily, verily, I say unto you, He that heareth My words, and believeth on Him that sent Me, hath eternal life, and cometh not into condemnation, but hath passed from death to life." Thus believing alone, and regeneration, is perfection in life; for God is never weak. For as His will is work, and this is named the world; so also His counsel is the salvation of men, and this has been called the church. He knows, therefore, whom He has called, and whom He has saved; and at one and the same time He called and saved them. "For ye are," says the apostle, "taught of God." It is not then allowable to think of what is taught by Him as imperfect; and what is learned from Him is the eternal salvation of the eternal Saviour, to whom be thanks for ever and ever. Amen.”
