Historically speaking religion has always (wrongly) been used to supporting the war. I can’t for the life of me understand how giving blessings to soldiers on their way to war can ever be Christ’s wish. The primary objective of war is to kill your fellow man.
As a Christian, I believe in the New Covenant, but the Old Covenant was more ambiguous concerning war. They condemned murder but not killing for a just cause.
Jesus Christ never used violence, and I think we should follow in his footsteps. However, ethical dilemmas can – and do – arise. The use of force is never condemned entirely, even though I think that the term “war” in the Scriptures often alludes to a Spiritual War. In such a war, all the guns in the world would be of no help.
