In pp. 77–79 of The Defense of the Faith (first edition), Cornelius Van Til addresses the fundamental differences between Christian and non-Christian perspectives on ethics, particularly focusing on the role of the will of God as foundational to ethical systems. Van Til begins by asserting that God’s will is absolute and self-determinative. God is eternally good, not becoming good through a process, but being so by his very nature. Unlike humans, God does not have to achieve goodness; it is intrinsic to his eternal character. Therefore, God is both absolutely necessary and absolutely free.
Van Til introduces a key distinction between Christian and non-Christian viewpoints. Christians uphold the concept of an absolutely self-determinative God, who is the necessary presupposition for all human activity. Non-Christian ethics, however, assume that if the Christian God were real, he would stifle ethical activity. This is because non-theistic views perceive God and man as having wills conditioned by an environment, implying that God must also achieve goodness through a process.
Van Til critiques Platonic philosophy, noting that Plato’s conception of “the Good” was ultimate, but his god was not. For Plato, “the Good” was abstract and separated from a fully personal God, leaving the ultimate reality as dependent on the element of Chance. Thus, even if Plato spoke of the Good, it was not self-determined or sovereign in the Christian sense. Modern idealist philosophers tried to build on Platonic thought by proposing an “absolutely self-determinative Experience,” but ultimately failed, according to Van Til, because they made God dependent on the space-time universe, blending time and eternity. As a result, God became dependent on external processes rather than being sovereign over them.
The core ethical difference between Christianity and non-Christian systems is the acceptance or rejection of an ultimately self-determinative God. Van Til argues that without the presupposition of God as absolute, there can be no coherent or purposeful human experience, including ethics. The absolute sovereignty of God is not a hindrance to human responsibility but rather its foundation.
Van Til makes a point to distinguish Christian doctrine from philosophical determinism. While both affirm necessity, philosophical determinism is impersonal, suggesting that everything is determined by blind, impersonal forces. Christianity, in contrast, asserts that the ultimate reality is personal; God’s sovereign will underlies the possibility of genuine human freedom and responsibility.
