Dave Rich examines the foundational ethical frameworks of deontology and teleology through a Christian lens. Deontology emphasizes rules-based ethics where acts conform to authoritative commands, while teleology focuses on purposes and intended results. Rich explores how secular systems like utilitarianism and ethical egoism attempt to establish moral authority apart from God, yet ultimately fail to answer the critical question: "Says who?"

The presentation demonstrates that Christian ethics incorporates elements of deontology and teleology but grounds both in God's personal authority revealed through Scripture. Believers are called not merely to follow rules or pursue favorable outcomes, but to obey God's commands while cultivating right motivations and godly character. Through examining various philosophical systems—from Kantian categorical imperatives to utilitarian calculus—Rich shows how every secular attempt to establish ethics without God collapses under the weight of its own inconsistency. True Christian ethics recognizes that God's commands carry inherent authority, that our purposes must align with His glory, and that developing Christ-like character matters eternally.
