Chapter 8 [VII.]—(2) Whether There is in This World a Man Without Sin.
[2nd.] If, however, I am asked the second question which I have suggested,—whether there be a sinless man,—I believe there is not. For I rather believe the Scripture, which says: “Enter not into judgment with Thy servant; for in Thy sight shall no man living be justified.”[1] There is therefore need of the mercy of God, which “exceedingly rejoiceth against judgment,”[2] and which that man shall not obtain who does not show mercy.[3] And whereas the prophet says, “I said, I will confess my transgressions unto the Lord, and Thou forgavest the iniquity of my heart,”[4] he yet immediately adds, “For this shall every saint pray unto Thee in an acceptable time.”[5] Not indeed every sinner, but “every saint;” for it is the voice of saints which says, “If we say that we have no sin, we deceive ourselves, and the truth is not in us.”[6] Accordingly we read, in the Apocalypse of the same Apostle, of “the hundred and forty and four thousand” saints, “which were not defiled with women; for they continued virgins: and in their mouth was found no guile; for they are without fault.”[7] “Without fault,” indeed, they no doubt are for this reason,—because they truly found fault with themselves; and for this reason, “in their mouth was discovered no guile,”—“because if they said they had no sin, they deceived themselves, and the truth was not in them.”[8] Of course, where the truth was not, there would be guile; and when a righteous man begins a statement by accusing himself, he verily utters no falsehood.
