Because Robert E. Lee esteemed loyalty to his native state of Virginia above some of the basic principles he believed, his misplaced loyalty cost multitudes their lives. Many Christians likewise justify their actions, which are in basic conflict with the Scriptures and the nature of the Lord they claim to serve by esteeming loyalty to their nation, denomination, or other institution, above the basic principles of the faith.
This is not to in any way imply that loyalty to our nation, denomination, or even our company, is wrong.
