Hey EndofMysteries,
I actually registered an account just to respond to this post, because I've been thinking about these same issues a lot recently.
I think currently I fall somewhere between category A and B. For awhile after leaving the JW's I simply set aside matters of faith, though I began attending a Christian church with my parents in 2008. The reason for that....well....I can't say that I experienced a 100% bona fide divine miracle, but something very unusual happened that made me think "Hey maybe this God fellow actually is up there." I've since had other experiences which I think are more than mere coincidence. I can elaborate on these in a future post if people want.
Right now though I have serious doubts about the divine authorship of the Bible. Oddly enough, the reason for these is an issue which does not personally concern me at all: homosexuality.
But let me back up a bit. I initially believed, as I always had, that the Bible was word-for-word from the mouth of God. Two scriptures made me reconsider this idea: 2 Tim 4:13 and 1 Cor 7:25.
2 Tim 4:13 reads, "When you come, bring the cloak that I left with Carpus at Troas, and my scrolls, especially the parchments." The idea that this sentence came straight from the mouth of God seemed ludicrous to me. Imagine God saying, "Okay Paul, what I'm going to tell you next is of the utmost importance, and will benefit Christians for millenia to come: Tell Timothy to bring the cloak you left in Troas. Okay that's enough for today, we'll write more holy scripture tomorrow." It seemed to me that this was a personal remark of Paul's, nothing more. However this begs the question, "If this passage is not divinely inspired, than what other portions of the Bible are not?"
The other scripture was 1 Cor 7:25, which reads: "Now concerning virgins I have no command of the Lord, but I give an opinion as one who by the mercy of the Lord is trustworthy." (NASB) It seems impossible to reconcile the teaching that "All scripture is inspired of God" with this verse here. Paul explicitly says "What I'm about to tell you is not divinely inspired; it's my opinion." He then proceeds to tell the Corinthians that they ought not to get married, since they will experience more tribulation. As I considered the verse this troubling thought occurred to me: Fundamentalist Christians believe that this verse, like all Bible verses, is inspired of God and yet, if the church as a whole heeded this advice, Christianity would die out within one generation.
But as I said in the beginning the issue that troubles me the most right now is the Bible's stance on homosexuality. There are a few reasons for this.
I used to believe that homosexuality was a lifestyle choice, one that could be changed if the person wanted. I thought to myself "If homosexuality is a sin, God can help people change." Well, I've since had to change my thinking. I've since met a few gay people in person and gotten to know them, and I have found out that they did not choose their sexual orientation; rather they discovered they were attracted to the same sex at an early age, like 12 or 13. I also read a book written by a gay Christian called "Stranger at the Gate." In it the author, Mel White, relates how he began feeling homosexual urges at an early age and spent the next 30 years trying to "cure" himself. He tried unceasing prayer, thousands of dollars worth of counseling, faith healings, exorcisms, electroshock therapy, isolation, he was even driven to attempt suicide twice, all the while experiencing emotional turmoil and frustration at the fact that his orientation simply could not be changed, only supressed, and with disasterous results.
After reading this book I thought, "I can't imagine that God of love would sentence his children to live a life of loneliness and misery, simply because they were born different." Even worse is the passage at Romans 1:18-27, which seems to imply that homosexuality is caused by one's own godlessness and idolatrous ways. Oh yeah, there's also the matter of the gay penguins. (http://en.wikipedia.org/wiki/Roy_and_Silo) Were Roy and Silo so wicked that God "gave them over to shameful lusts"? At this time I can't imagine a loving God imposing such an impossible restriction on people born gay. It doesn't make sense. What does make sense, however, is that these words were written by a fallible man who knew nothing about the workings of human sexuality.
I think that's all I got for now. I'm in the process of rereading the Bible with a more-critical eye. So far I've come across a good number of things that cast serious doubt on Jehovah's claim to be all-loving. And I'm not even out of Genesis!
