We reason from the Scriptures. We do not reason autonomously. Politics puts great emphasis on loyalty. Each political party seeks to instill a deep sense of loyalty in its members, for this is essential to the party's success. The goal is to have each member vote for the entire party ticket, and to have each politician support the party leadership and endorsed candidates.
Loyalty is honored and rewarded.
Loyalty, or faithfulness to a just person, ideal, or legitimate cause, is a virtue. However, if that loyalty becomes our highest good, the object of our loyalty becomes an idol. For we Christians our highest loyalty must always be to Christ our Lord. If this be so in regard to one of the most natural and biblically blessed loyalties among men, how much more in regard to political loyalties. We must never lose sight of the fact that our first allegiance is to Jesus Christ, and we must never compromise that allegiance, regardless of what it might cost us politically.
