God is sovereign.God is perfect.God is immutable.God created everything.God is triune.The Son of God was incarnate in Jesus Christ.The essential tenets of classical theism regarding the doctrine of God can be stated fairly easily. However, questions have been raised regarding the coherence of these beliefs taken as a whole. Some have seen fit to abandon classical theism. Others have acknowledged tensions in the traditional concept of God and have sought to resolve them by means of making significant concessions. Jay Wesley Richards believes that classical theism with its biblical norm can and ought to be maintained. He shows how a philosophical defense, using the analytical tools of modal logic, can be mounted that preserves traditional Christian beliefs. Richards astutely defends essentialism, arguing that it is both intrinsic to the Christian understanding of God and preserves the contingency of creation and the God-world relation. To further clarify and defend his proposal he engages appreciatively and critically the thought of Karl Barth and Charles Hartshorne as well as addressing the related and currently debated matters of divine simplicity and immutability.
