According to presuppositional apologetics, only the Christian worldview provides the necessary preconditions for knowledge, logic, and morality. This paper argues that the rejection of classical theism within certain contemporary presuppositional circles undermines the very epistemological claims it seeks to defend. If God is composed of parts or mutable in any sense, He would be contingent and thus unable to serve as the necessary foundation for logic, morality, and human reasoning. The paper will engage with contemporary critiques of classical theism within Reformed apologetics and demonstrate how a return to a robust classical understanding of God strengthens the presuppositional argument.
Only by reaffirming classical theism, can presuppositional apologetics maintain the coherence and transcendental necessity of the Christian worldview, effectively countering secular and non-Christian perspectives that rely on autonomous human reasoning.
