Christian men are not at war with any man that walks the earth. We are at war with infidelity, but the persons of infidels we love and pray for; we are at warfare with any heresy, but we have no enmity against heretics; we are opposed to, and cry war to the knife with everything that opposes God and his truth: but towards every man we would still endeavour to carry out the holy maxim, "Love your enemies, do good to them that hate you."
The Christian soldier hath no gun and no sword, for he fighteth not with men. It is with "spiritual wickedness in high places" that he fights, and with other principalities and powers than with those that sit on thrones and hold sceptres in their hands. I have marked, however, that some Christian men—and it is a feeling to which all of us are prone—are very apt to make Christ's war a war of flesh and blood, instead of a war with wrong and spiritual wickedness. Have you never noticed in religious controversies how men will fall foul of each other, and make personal remarks and abuse each other? What is that but forgetting what Christ's war is?
We are not fighting against men; we are fighting for men rather than against them. We are fighting for God and his truth against error and against sin; but not against men. Woe, woe, to the Christian who forgets this sacred canon of warfare. Touch not the persons of men, but smite their sin with a stout heart and with strong arm. Slay both the little ones and the great; let nothing be spared that is against God and his truth; but we have no war with the persons of poor mistaken men. Rome we hate even as we abhor hell, yet for her votaries [devoted followers] we ever pray. Idolatry and infidelity we fiercely denounce, but the men who debase themselves by either of them are the objects not of wrath, but pity.
We fight not against the men, but against the things which we consider in God's sight to be wrong. Let us always make that distinction, otherwise the conflict with Christ's church will be degraded into a mere battle of brute force and garments rolled in blood; and so the world will again be an Aceldama—a field of blood. It is this mistake which has nailed martyrs to the stake and cast confessors into prison, because their opponents could not distinguish between the imaginary error and the man. While they spoke stoutly against the seeming error; in their ignorant bigotry they felt that they must also persecute the man, which they need not and ought not to have done.
I will never be afraid to speak out my mind with all the Saxon words I can get together, and I am not afraid of saying hard things against the devil, and against what the devil teaches; but with every man in the wide world I am friends, nor is there one living with whom I am at enmity for a moment any more than with the babe that has just been brought into the world. We must hate error, we must abhor falsehood; but we must not hate men, for God's warfare is against sin. May God help us always to make that distinction.
