Catechesis: Good Works

Above all this false Epicurean delusion is to be seriously rebuked and rejected: some imagine that faith, and the righteousness and salvation that they have received, cannot be lost through sins or wicked deeds, not even through willful and intentional ones. They imagine that a Christian retains faith, God’s grace, righteousness, and salvation even though he indulges his wicked lusts without fear and shame, resists the Holy Spirit, and purposely engages in sin against conscience.—FC SD IV:31
