The Christian militant is challenged to follow his convictions and to refuse all compromise with means and weapons that are unchristian. If he believes firmly that war is always an unchristian way of seeking to achieve a righteous end, he should be loyal to that conviction in the face of any pressure or danger, and be no less courageous than the soldier in battle. He should be loyal to his conviction even in the face of aroused public opinion and popular clamor. He should refuse to be swayed by frenzied passion or surface patriotism, but should remember that the truest patriotism is shown only by loyalty to one's highest moral convictions.
