Open theism, also known as
openness theology and
free will theism, is a
theological movement that has developed within
evangelical and
post-evangelical Protestant Christianity as a response to certain ideas related to the synthesis of
Greek philosophy and
Christian theology. It is typically advanced as a biblically motivated and philosophically consistent theology of human and divine freedom (in the
libertarian sense), with an emphasis on what this means for the content of God's foreknowledge and exercise of God's power. It has been said that open theism triggered the "most significant controversy about the doctrine of God in evangelical thought" in the late 20th and early 21st centuries.
