17 So faith also, if it have not works, is dead in itself.
18 But some man will say: Thou hast faith, and I have works: shew me thy faith without works; and I will shew thee, by works, my faith.
19 Thou believest that there is one God. Thou dost well: the devils also believe and tremble.
20 But wilt thou know, O vain man, that faith without works is dead?
21 Was not Abraham our father justified by works, offering up Isaac his son upon the altar?
22 Seest thou, that faith did co-operate with his works; and by works faith was made perfect?
23 And the scripture was fulfilled, saying: Abraham believed God, and it was reputed to him to justice, and he was called the friend of God.
