For most of Christian history, God was understood to be "simple." It was a staple of articles of faith to confess a God "without parts or passions." But today, divine simplicity is seen as either irrelevant or a vestige of "classical theism." Neither is quite right. The Simplicity of God argues that the doctrine is often misunderstood, but in the right light it can play a vitalizing role in Christian thought and spiritual practice. In this companion, Jonathan Platter presents an integrated account of divine simplicity, and he goes further to explore the difference it makes for the doctrines of Trinity, creation, incarnation, and eschatology. Grounded in Scripture, the history of doctrine, and contemporary systematic theology, The Simplicity of God offers a thorough introduction to the doctrine in an accessible format.
