Open theism is a recent theological movement that has developed within evangelical and post-evangelical Protestant Christianity as a response to certain ideas that are related to the synthesis of Greek philosophy and Christian theology. Several of these ideas within classical theism (a designation which is not to be taken as inclusive of all of orthodox theism) state that God is immutable, impassible, and timeless. For several versions of classical theism, God fully determines the future; thus, humanity does not have libertarian free will, or, if free, that its freedom must necessarily be compatible with God`s determining actions. Open theists argue that these attributes do not belong to the God of the Bible and are at odds with personhood.
