1 John 1:6-8

Revised Standard Version Catholic Edition

⁶ If we say we have fellowship with him while we walk in darkness, we lie and do not live according to the truth; ⁷ but if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. ⁸ If we say we have no sin, we deceive ourselves, and the truth is not in us.
