The Moral Argument for God

Chris Cahill · 6 min read · First published 2024-10-27

Moral arguments for God ask whether moral truths or obligations are best explained by a divine source. “To each their own” is not a standard name for this argument. This reflection considers Christian replies to the Euthyphro dilemma and to accounts of morality grounded without God.

The Euthyphro Problem: God and Goodness

One of the primary challenges to the Moral Argument arises from "The Euthyphro Problem," a philosophical question rooted in Plato's dialogue "Euthyphro." This dilemma poses a critical inquiry: “Is something good because God commands it, or does God command it because it is good?” This question raises the concern that if moral goodness is merely a product of divine command, then morality could become arbitrary—God could potentially command anything, even actions we find morally abhorrent, like murder or cruelty. On the other hand, if God commands actions because they are inherently good, it suggests that moral truths exist independently of God, indicating that we do not require a divine source for our understanding of morality.

To address this dilemma, it is essential to understand that God's nature is fundamentally good. As expressed in Psalm 119:68, “You are good and do good; teach me your statutes.” God's commands are not random; they arise from His perfect and unchanging essence. Thus, moral values are neither independent of God nor whimsical directives. Instead, they are a reflection of His character. Consider the analogy of a compass: just as a compass provides a reliable point of reference for navigation, God's nature serves as the ultimate benchmark for moral guidance. Without such a compass, individuals can easily lose their moral bearings, just as society can deviate from true morality without the direction provided by God.

Capital punishment reveals disagreement about justice among both religious and secular thinkers. Disagreement alone does not establish that morality is subjective or that only one account can ground moral truth.

Secular Ethics or Human-Centric Morality: Ethics Without God

A notable challenge to the Moral Argument comes from advocates of "Human-Centric Morality." These individuals claim that morality can be established through human well-being, empathy, and social cooperation, independent of any divine influence. They suggest that ethical principles can arise from evolutionary processes that foster social behaviors beneficial for group survival and individual welfare. In this framework, moral values are viewed as products of human experiences and social agreements rather than divine insights.

Theistic critics ask what grounds moral obligations beyond social agreement. Secular moral realists also defend objective moral truths. Their accounts require examination rather than being equated with nihilism or approval of atrocities. Isaiah 5:20 gives a biblical warning against calling evil good.

Animal welfare raises questions about suffering, responsibility, and the worth of living creatures. People may disagree within religious as well as secular traditions. That disagreement invites careful moral reasoning rather than a verdict about everyone’s moral foundations.

The Moral Argument for God's Existence

The affirmation of human dignity can be grounded differently across philosophical and religious traditions. Christians often understand that dignity through Genesis 1:27 and humanity made in God’s image.

Opposing human trafficking or genocide affirms that grave harm deserves more than cultural indifference. Theists and secular moral realists offer different accounts of that conviction. We can examine their reasons while standing together against harm.

Carrying this into life

The Euthyphro dilemma and secular accounts of morality leave questions to examine. This reflection presents God’s character as a Christian foundation for love, justice, and compassion, while allowing other accounts a fair hearing.

Micah 6:8 directs attention to acting justly, loving mercy, and walking humbly with God. Whatever questions remain about the moral argument, we can bring that passage into the way we treat the person across from us. Let the search for understanding make room for practical care.

We can keep asking without turning the person across from us into an opponent. May wisdom deepen our attention, grace soften our conversation, and shared curiosity make room for understanding.
