Conservative Catholic theologian George Weigel explains why the U.S. Catholic bishops are wrong to conclude war against Iraq is immoral. Andrew Sullivan agrees with him (scroll down), but doesn’t understand why Weigel and his lot aren’t guilty of hypocrisy, given this “dissent” from “Church teaching.” What Andrew doesn’t appear to understand is that in Catholicism, there are levels of Church teaching, and not all of them carry the same claim on the individual Catholic’s conscience. Mark Shea offers a short tutorial (scroll down). This is a crude analogy, but it’s sort of like the difference between a cop ordering you not to cross the street, and suggesting that crossing the street now would be inadvisable.
