Check out two posts critiquing American Christian support of war:
The Warmonger’s Fruit of the Spirit, which begins: "It seems sensible and logical that followers of someone called the Prince of Peace would not act like they are following Mars, the Roman god of war.
As I have maintained whenever I speak about Christianity and war, if there is any group of people that should be opposed to war, empire, militarism, the warfare state, an imperial presidency, blind nationalism, government war propaganda, and an aggressive foreign policy it is Christians, and especially conservative, evangelical, and fundamentalist Christians who claim to strictly follow the dictates of Scripture and worship the Prince of Peace."
"Defenders of U.S. wars and military interventions look like the majority of Americans. They also dress like them, eat like them, work like them, play like them, and talk like them. However, it is sometimes impossible to communicate with or make sense of them because some things they say have their own peculiar definition.
To really understand these defenders of U.S. wars and military interventions, one needs a warmonger's lexicon. To get started, I propose the following entries:
Just war: any war the United States engages in.
Good war: any war in which the United States is on the winning side.
Defensive war: any war the United States starts."
It seems to me that the cause of peace (and the prophetic role and witness of Christians) is harmed by the politicization/ideologization of faith in the American context - i.e., Christians aligning themselves with one political party or ideology (mainly, conservative Republican) or another.
As the author of the above blog posts notes, it is ironic and worse, that those calling themselves "Christians," i.e., followers of Jesus, the "Prince of Peace" and the one who said "blessed are the peacemakers," should be so strongly in support of the U.S. war machine.
Christians in America need to take another look at Biblical values, and what it means to stand for the teachings of Jesus. We need to get away from party politics, and away from knee-jerk support of American war efforts, and back to a role of critiquing the actions of our government from the perspective of Biblical values, across the board.
The world needs Christians to be a force for peace, not for war.
