That is not an unreasonable response.
But, how thoroughly have you explored these theistic possibilities? How do you know that you have explored them thoroughly enough? And that you are not short-changing yourself by dismissing the possibilities too quickly, too easily, or through bias?
- These are not justifications that you would ever owe me or anyone else, of course. I was just asking them rhetorically.
I have explored them to the point I felt satisfied. I consider that to be enough.
That makes no sense to me at all. Probably no one on Earth holds the same exact idea of God as I do, at the exact same time. And if they did or didn't, so what? I neither expect it, nor demand it, because that would be silly, and pointless.
So why are you using this expectation as some sort of criteria for religious or theological validity?
I wouldn't expect any two people to hold the exact same concept of God down to every single detail. That's not what I am talking about. Rather, I would expect that new revelations would erase the major divides, such as whether Jesus is God, but it didn't happen so far. That's something really trivial to solve with revelations.
