The problem isn't really blind faith. I've run into very few people of any religion, who, as adults, will believe absolutely anything they are told.
Allow me to expand on my definition of Blind faith.
Here's a hypothetical situation: John Doe, without prior exposure to religion, goes to church one day and learns that if he gives a cookie to a homeless person once a day, he will go to heaven. He's been told of the wonders heaven holds and all that good stuff. John continues to go to church and learns of hell, sin, the devil and so on. John get's baptized due to his new found faith in God and desire to be 'saved.' John lives a Christian lifestyle according to what his preacher tells him.
Why does John believe this in the first place? Humans naturally fear that which they cannot control or do not understand. Death is something nobody knows for sure what happens afterwards or when that time will come. The thought of heaven (Only promised in the Bible to 12,000 people of each of the 12 tribes of Israel [Book of Revelation Ch. 7]) when offered hell as the alternative (Hell isn't even cut and dry anywhere in the bible and the closest thing to a hellish demise is the lake of fire, which in the bible, fire always [to me] meant complete destruction) has been wildly misused and lied about to give people a sense of comfort and something to hope for and fear at the same time. The belief in two polar opposite outcomes do two things: Heaven calms a very fundamental fear that we're all exposed to at a very young age while Hell keeps us coming back each Sunday so we can pay our God tax, say a hail mary and be saved once again. My definition and example of blind faith here is in reference to belief without proper research and deciphering the teachings and content of the bible on your own.
Random example: Ask any Christian if the God of the Bible would encourage you to read the Quran and 99 out of 100 would say absolutely not... if they had read their own book, however, they may find that Jesus encouraged doubting or testing their faith in God to strengthen it. What better way to test your faith than explore others? A stretch? A little. But at least I've done my own personal 'fact checking' (I realize the Bible cannot be considered a book of fact but you get my usage) and found my faith through the book itself and not some professed messenger of God.
People generally pick up their ideological/religious beliefs as children/teenagers, then they are, for the most part, set for life. (I won't really get into my feelings on indoctrination here, just know that I strongly oppose it.) What normally happens is people will agree with anything that fits their preconceived notions. If it doesn't, they will examine it more critically, or in the case of religion, typically outright ignore it.
We're all given our perception of the world from birth to adulthood. I'll agree that "generally" you're correct, but the belief in God is not genetic, therefore the mind has the ability to change that perception based on life events and experiences. A parent who loses a child at a young age has a strong tendency to either increase their faith in God (believing their child has gone to heaven with God) or completely remove that belief from their makeup entirely (questioning how their God could allow that to happen).
I got out my bible app and started reading him the "bad verses." He had no problem whatsoever with completely ignoring them. They were either mistranslations, out of context, or somehow modified to say the opposite of the "true Christian message." I then read a few of the more popular "good verses" and asked what he thought about them, how many of them were translation errors/corruptions/out of context, and he wouldn't even entertain the idea of it. Even after all this, I'm pretty sure the idea didn't get through at all. He most likely still thinks I was attacking his religion by reading the bible.
The bible has a very interesting timeline. If you take a look at the doings of God from start to finish, you find that 'terrible' things that were done went from a high frequency, to a low frequency. The best explanation I could ever come up with was that God learned as time went on that humans simply could not please a perfect God. The punishments for wrong doing went from wiping out villages to 'wearing the scarlet letter'. People make the argument that God should be able to see the future if God truly is omnipotent, and maybe he has and this is all part of the plan, but I think that with our gift of free will, he gave up that luxury. He's learning as a deity as we progress as a species. The bible is quite deplorable if you look only at the bad, but reading into the teachings of Christ and the meaning of his death (not the 'pay for our sins' part), you find a sort of transition from "DO WHAT THE **** I TELL YOU OR DIE" God to a "Look, you're gonna make mistakes, just keep trying" God.
I, personally, cannot wrap my head around this belief. If the bible really is so corrupted by evil ideas, why would anyone base their life around it? There's no way to tell what is genuine and what isn't. They could very easily be worshipping Satan without knowing it (note: By Satan, I mean in the classic sense, the inherent evil in humanity, not necessarily the deity ). Heck, the whole thing could be supporting the "bad guy", with all the good parts being the forgeries, and nobody would even know it. I'm not saying this is the case (though God does commit a large number of detestable acts, mostly in the Old Testament) but the idea should at least occur to people.
While I've never thought of it that way... you could be right. I'm not closed minded enough to think that I'm right in my belief of a man made document, influenced by a seemingly absent yet loving all powerful being. I realize that my personal faith is quite the stretch.
become corrupt as they gain power
Exactly.
