THE EIGHTH COMMANDMENT: LIVE IN TRUTH
The Eighth Commandment is about telling the truth and living in truth. According to the Catechism, “The disciple of Christ consents to “live in the truth,” that is, in the simplicity of a life in conformity with the Lord’s example, abiding in his truth. “If we say we have fellowship with him while we walk in darkness, we lie and do not live according to the truth.”
(CCC no. 2470)
