I watched a video by an ex-Christian a while back, and he says he doesn’t identify as an atheist because there are so many concepts of god. He says that if someone asks him if he’s an atheist, he asks them to tell him about their god… and then decides whether he’s an atheist or not about that god. In that sense, as others have said, even Christians can worship very different iterations of God. Some Christians, like myself, have at times developed a view of God as someone who’s obsessed with our good behavior, but have subsequently recovered (and continue to recover) a sense of grace and mercy in how we view that God (and ourselves in relation). Still, I would like to believe that I’ve come to see God a little bit more clearly rather than switched to a different one, though some “raised in the church” Christians can still have what feels like a conversion experience later in life that probably feels that way.
