'Blameless' in the Bible

so that you may be men of transparent character, and may be blameless, in preparation for the day of Christ,

so that you may always prove yourselves to be blameless and spotless--irreproachable children of God in the midst of a crooked and perverse generation, among whom you are seen as heavenly lights in the world,

as to zeal, a persecutor of the Church; as to the righteousness which comes through Law, blameless.
