The Uncaused Cause of Theism is not the God of pantheism. Pantheism affirms that an unlimited and necessary being exists but denies the reality of limited and finite beings. Theism begins with real, finite, contingent changing being(s), and from this it reasons to a real, infinite, necessary, unchanging being. So the theistic God is not the same as the god of pantheism.

The denial that a human being is finite and changing is self-defeating. A pantheist did not always believe this way; he came to believe this way by some process of “enlightenment.” But if he went through some changing process, then he is not an unchanging being after all.
