Paul Churchland's criticisms of mind-body dualism

What are Paul Churchland's criticisms of mind-body dualism? Do they make a strong case against the possibility of dualism? Can Churchland’s materialist account of mind account for what Thomas Nagel calls “the subjective character of experience”? What is John Hick's "Soul Making Theodicy"? Do you think it is an adequate response to the atheists' "Argument from Evil"?
