I don't understand why American Catholic Republicans are willing to
excommunicate repudiate the likes of John Kerry for his stance on abortion, but not George Bush for his stance on the Iraq War. I understand the opposition to politicians who support abortion by American Catholic Republicans -- the Pope has said abortion is murder and that's pretty much the end of it. But by that exact same reasoning, American Catholics should reject George W. Bush and the prosecution of the Iraq War.
This article from the Houston Catholic Worker makes it pretty clear that Pope John Paul II opposed the Iraq War and considered it a grave sin, in no way a "just war" under Catholic doctrine:
In the weeks and months before the U.S. attacked Iraq, not only the Holy Father, but also one Cardinal and Archbishop after another at the Vatican spoke out against a "preemptive" or "preventive" strike. They declared that the just war theory could not justify such a war. Archbishop Jean-Louis Tauran said that such a "war of aggression" is a crime against peace. Archbishop Renato Martino, who used the same words in calling the possible military intervention a "crime against peace that cries out vengeance before God," also criticized the pressure that the most powerful nations exerted on the less powerful ones on the U.N. Security Council to support the war. The Pope spoke out almost every day against war and in support of diplomatic efforts for peace.
John Paul II sent his personal representative, Cardinal Pio Laghi, a friend of the Bush family, to remonstrate with the U.S. President before the war began. Pio Laghi said such a war would be illegal and unjust. The message was clear: God is not on your side if you invade Iraq.
When I hear Catholics defending this President, I have to shake my head in disbelief. The teachings of the Church and of Christ are pretty clear on this point, and I don't understand why a Democrat who supports the right to an abortion should be reviled and opposed, but when it comes to a Republican who wages an unjust war responsible for the deaths of literally tens of thousands of people he gets full-throated, unstinting, uncritical support. It's completely inconsistent and it baffles me.
Update: Post edited to replace the word "excommunicate" in the first paragraph with "repudiate" -- as Allen pointed out in the comments, excommunicate has a very specific meaning that does not apply to a non-Catholic, I apologize for the poor initial word choice.
