Oh, the irony!
Well, the funny thing is, is that by that definition of liberalism, the definition of liberalism changes over time (as does that of conservativism--or is it conservatism? Whatever, moving on). Things that need (or are thought to need) reform change over time. So the opinions of a liberal in medieval Poland would be different from that of a liberal in modern-day America, presumably. Likewise, Jesus' opinion of liberalism is very different from today's average liberal's opinion of it. If Jesus were to come back to Earth now as a human again, and live among us again, his opinions would probably be more conservative. At least, he would share opinions with what most conservatives believe today: the beliefs of the right to life for all people, the definition of marriage being between one man and one woman, and the other stuff. But I don't think I'll get into what his opinion on Iraq is likely to be. ;)
