The most practical consequence of theism is that it gives moral obligation a foundation that doesn't shift with the majority. My opponent may say we can be good without God, and sure, Kant grounded duty in reason. But a contingent, ordered universe still begs for a necessary ground, and Aristotle's unmoved mover is a rational candidate. Imagine a trolley case where the crowd prefers sacrificing one; if morality is only human preference, Rawls's veil hides nothing stable. Theism explains why justice and Mill's general happiness have real weight. That's my case.

Take the civil rights movement: King's Letter from Birmingham Jail didn't argue that segregation was merely unpopular; it appealed to a law above majority opinion, drawing on Augustine and Aquinas. That's the practical force of theism. My opponent's burden-of-proof point is fair, and the shrinking god of gaps pattern is a real caution. But the core theistic claim isn't thunder or disease; it's Aristotle's necessary ground for a contingent order. And conflicting revelations show people get religion wrong, not that no ground exists. Without that ground, Rawls's veil and Mill's harm principle float on preference. So theism still offers the stronger foundation.

On the 2020 PhilPapers survey, more professional philosophers accepted theism than atheism, roughly 20 percent to 19. So the "reasonable default" isn't as settled as my opponent suggests. I grant a need isn't evidence. But my argument isn't "belief comforts us"; it's Aristotle's necessary ground for contingent order, which is a metaphysical inference, not a god of gaps. Conflicting revelations show human error, not no ground. And Rawls's veil still needs a stable basis for justice. The other side's burden point is fair, but theism meets it with a rational ground, not just tradition.
