During his whirlwind tour of the United States, Pope Francis used his speeches to the U.S. Congress and the United Nations to articulate his views on the family, human life, violence, the environment, social justice, and many other issues. No one doubts the sincerity of the Pope’s pursuit of goodness. And surely no one disagrees with his condemnation of aggression and hatred against the young, the vulnerable, and the poor. But too often, his political naiveté got the better of him. As a result, many of his controversial pronouncements, if rigorously implemented at the policy level, would pose a threat to overall human welfare. Specifically, his ideas about violence, the environment, and markets deserve a critical look.
