A lightning rod

Someone asked once on the blog if a person could be a Catholic in good standing and at the same time disagree with the Pope.

I saw a post at America magazine's blog today (An interview with a lightning rod) about Fr. Richard McBrien .... if anyone fits the description of a Catholic in good standing who dissents, it would be him. Fr. James Martin SJ describes him in his post as 'the always-interesting, always-provocative, always-hardworking, always generous-with-his-time, always-worth-listening-to Richard McBrien, the Catholic theologian teaching at Notre Dame. I've always profited from Father McBrien's writings, particularly his book "Catholicism" and "Lives of the Saints," and have found him always to be a gracious man, even on the rare occasions when we've disagreed. Others are not so generous. Paulson reports one Catholic blogger calling him a "heresiarch," that is, leader of heretics.'

So the answer to the asked question is yes :)
