Those are not experiences. Those are beliefs. You cannot experience that kind of thing. But yes I am pretty sure those beliefs will effect their experience of God. After all, our beliefs affect our experience of most things. Our immediate experience of reality is subjective. The objective is an abstraction.
But you know… all of this is really missing the point. Whether you see God as an objective reality or not, this doesn’t change the fact that there is no objectivity or absoluteness inherent in a religious or theistic perspective. There is no objectivity because there is no basis for a reasonable expectation for others to agree with anything you say about God let alone what you claim God says. There is nothing absolute because the things people say about God or about what God says varies from person to person as well as from one religion to another. So this is at least as subjective and relative as anything coming from social convention.
