Since the rule of Constantine in the 4th century A.D., church leaders have lived precariously close to showing preference and promoting one political leader over another. The Rev. Billy Graham came to regret his close ties to Richard Nixon, who used "America's Pastor" to his political advantage.
A prophetic distance must be maintained, allowing space between what the Spirit and the Word might say in any given situation, and the political leader or policy in question. The role of prophetic analysis requires distance so as to avoid compromise.
Then, too, we see how important it is not to make our rendition of the Gospel synonymous with a particular view of economics, role of government, social management or civic engagement. After watching Christian leaders running to the beck and call of Nixon, Chuck Colson warned us that the kingdom of Christ does not arrive on Air Force One.
