Setting aside the God question looks wiser than Western insistence on answers. Why treat the Buddha’s refusal as a weakness rather than humility?

It can be humility, and there is something bracing about refusing to pretend to knowledge one does not have. The Christian reply is not that the Buddha should have speculated more, but that the question of God is not idle. If there is a Creator who made us for himself, then the deepest source of suffering is estrangement from him, and setting that aside would mean treating the wound while missing its cause. The claim is that God has stepped into history, so the question is no longer pure speculation but a response to something that happened.
