1) Were you indoctrinated by this religion since birth because your parents follow this religion, or did you become a Christian later in life?
I became a Christian later on. My parents were Christian, but they were that off-the-wall charismatic Christianity. Everything about their faith was utterly experiential so they never explained anything to me. I was never indoctrinated because there was no doctrine being spoken anywhere. I grew up observing all the insanity in that church thinking it was stupid and senseless. As for God, I didn't think about him, I didn't pray, I didn't read the bible or have it read to me, I didn't know the gospel. Christianity was the last worldview I considered as I was looking for answers/understanding of life as a teenager.
2) Do you believe that the Bible is the word of God (ie it's perfect, infallible, exactly how it should be, not just written by man)?
That's a very complicated question. I will say in very simple terms: Not as protestants do.
3) Do you believe that some or more of the detailed stories in the Bible (Adam and Eve, Noah, etc) are metaphorical or do you believe all are literal?
Metaphor. God spoke to people in the way they had to be spoken to.
4) If you think some are metaphorical, how do you determine which are metaphorical and which are literal? How do you reconcile the two?
Well that's pretty hard to determine, isn't it? For some things, such as Adam and Eve, there is a great deal of science that shows us mankind is over 50k years old and such. I think it's perfectly understandable as to why God would give us that story as a lesson of our relationship to him, although it certainly poses some theological challenges to protestants. Even some very intellectual ones to more thoughtful ones like Francis Schaeffer, who based much of his stance on the literal existence of Adam.
However, difficulty in figuring out the details shouldn't necessarily disqualify the entire thing. There is no sense in why that would be the case. Still, while trying to figure out theology in light of biological record, you have different sort of things that are hard to figure out. What about all the stuff with Israel? How many of the stories of that kingdom was real? If you believe God exists, there isn't much reason to believe he couldn't have done many of those miracles, but there isn't a whole lot of record of it all aside from the bible itself... but then there isn't much record of anything back then, and apparently Israel did pretty much get their ass kicked/subjected left and right by everyone else.
So looking at that, and the fact that most of anything taught was passed on to the majority by oral tradition, and even within the Old Testament there were times Israel lost the Torah and forgot about it... it's really hard to determine how much could have been pulled from other religions or how much in other religions could have been pulled from Israelites. They seemed to be pros as just going along with the beliefs of whoever they were among, so I doubt they would have stood out to been recorded much if they were some random slaves who barely followed their own God.
No matter what, in the end you have these Jews with this really freaking old book, and it has a lot of good stuff in there, then some crazy shit goes down with Christianity. It all obviously exists and had for some time. It's a bit loose, fairly mystical, and if you believe that
anyone today is actually pleasing God with their faith, then God must be pretty freaking merciful about our limited capacity to communicate, understand, and agree with each other.
As a practical example of that, I believe that scripture holds the doctrine of his name (Yahweh, basically), of knowing him by it, acknowledging it, calling on it, making it famous, etc. as a very important thing. Yet it seems that absolutely everyone has fucked up in that regard, and we can't even be sure how to pronounce it anymore. If people still come to faith, and scripture says that happens by him reaching to them, then he must be understanding and patient, even when they keep calling him Jesus or whatever else.
5) If they are metaphorical, then why do you follow it as an actual religion and not just fables or stories meant to teach a moral lesson?
That's what religion is, so I don't know what you mean. Do you mean like, believing God exists? That's something separate that happened on its own. Why think the bible's God is the God I believed in and not some other religion's God? That gets extremely... well, not exactly complicated, but just
long to explain.
6) Have you ever seriously sat down by yourself and critically thought about your religion and why you believe it?
Yeah, obviously, since I'm basically a heretic to Protestants with my loose views. You think that makes me a lot of friends in Christian circles? Yet I guess since I'm not an atheist you think I'm not being critical enough, or not holding myself to critiques enough or following their logical progression deep enough. To that I have to say: It's not that simple. Sorry.
