There are many questions that science cannot answer, but which religion can. Religion makes sense of things that science fails to.
If science cannot make sense of some problem or explain some phenomenon, it doesn’t necessarily follow that religion can. That something is beyond our current understanding doesn’t imply that some supernatural force must be at play; it just means that we are ignorant. Appealing to the supernatural as an answer doesn’t solve anything; it doesn’t further our understanding of the universe in any meaningful way. And if that’s the case, then we can carry on inquiring without it.
The truth of my theology is confirmed by my sensus divinitatis, the inner witness of the Holy Spirit in my heart.
What of those whose sensus divinitatis leads them to theological commitments that differ to your own? Why lend so much epistemic weight to your personal sensus divinitatis? What makes you think that your own sensus divinitatis is more reliable than that of someone of a different religion who feels just as strongly about his theological commitments as you do about yours?
Without belief in God, life is meaningless. There is no wonder or joy, only despair.
Some people believe that everything must be imbued with theological significance or else it has no significance at all; it’s meaningless. I don’t subscribe to this nihilistic worldview. When I gaze upward into stelliferous skies, I don’t feel as though life is devoid of meaning. The cosmos is awe-inspiring on its own; one need not view it through a theological lens to be enthused with wonder.
Why do you care? Why can’t you just let people believe whatever it is they want to believe?
Because ideas matter; ideas guide actions, which have real consequences. Too often, we find that political decisions are made on a religiously motivated basis. Such decisions affect us all, which is why we have an interest in examining the rationale behind them.
