Note 17 at Ro 14:22: This is specifically speaking of having faith that they could eat meat sacrificed to idols. "The Life and Epistles of Paul" by W. J. Conybeare and J. S. Howson renders this verse, "Hast thou faith [that nothing is unclean]? keep it for thine own comfort before God." Therefore, Paul was stating that those who have clear consciences about eating meat that has been sacrificed to idols, they should keep that faith to themselves and not practice it openly lest they offend the weaker brethren.
