The placebo effect is mostly bunk, actually. And while you may not have an ethical obligation to stop a fellow customer from buying a homeopathic product, it's unethical for the pharmacist to knowingly misrepresent sham treatments as effective.
I have no idea what you're getting at here.
If that's the case, then:
- God is indistinguishable in every measurable way from a god that doesn't exist.
- there can be no rational justification for belief in God.
If God truly is unknowable, then there's no way for him to "make Himself known" and there's no way to establish that someone is a "Messenger" of God.
What you just described IS irrational. In one sense, it's good that you're owning it. In another sense, it's perplexing to me why you would feel attachment to irrational beliefs.
The common themes I see: wishful thinking and a failure to think things through.
Beyond the fact that none of your criteria have anything at all to do with gods without begging a boatload of questions, it's inherently contradictory to say on the one hand that God can't be demonstrated and on the other hand say that it can be demonstrated that someone is a "messenger of God." If you could actually demonstrate this, then you would have demonstrated God, since the existence of a genuine "messenger of God" would imply that God necessarily exists. Your positoon contradicts itself.
Religion is designed to be paradoxical, God’s test if you like. If we want to project contradictions then we will. If we want resolve the paradoxes we will. An Unknowable God that can be known is a paradox that’s easily resolved for the faithful or rejected as irrational nonsense for the faithless. It’s a reflection of our own selves. We respond in personal ways to the illusory nature of reality.
