In this installment of Van Til Group, we turn to the section of Defense of the Faith (pp. 69–72), which begins the chapter titled “The Christian Philosophy of Behavior.” This section outlines the Christian perspective on ethics, drawing from the Reformed confessions to emphasize that human actions, or behavior, should aim to glorify God. It presents a confessional scheme focusing on three key aspects: the highest good (summum bonum) that humans should strive for, the criterion for achieving this good (which must be based on God’s revealed will in Scripture), and the motivation for pursuing this good, highlighting the necessity of faith and regeneration by the Holy Spirit for genuine ethical action.

The chapter then considers the relationship between ethics and the Christian philosophy of knowledge. It asserts that understanding God’s nature is fundamental to grasping the essence of Christian ethics, with God’s absolute personality serving as the ultimate interpretative category for human existence. This perspective contrasts with non-Christian views by emphasizing that the good is defined by God’s nature and will, rather than existing independently.

The section on “Man as Made in God’s Image” discusses the original moral perfection of humanity, created in the image of the Godhead, and underscores the derivative nature of human moral consciousness. Unlike non-Christian ethics, which may view moral consciousness as the ultimate arbiter of good, Christian ethics sees it as reliant on divine revelation. This foundational difference in epistemology between Christian and non-Christian thought underscores the Christian belief in a receptive rather than creative construction of moral knowledge, with humanity’s moral nature and external revelation jointly guiding ethical understanding.
