For me it is purely doctrinal. I have been in (and am in) really good congregations with lots of great, sincere people who feel that they are trying to serve God. I am fine living by the moral restrictions as a lot of have good scriptural support.
For most of my life I never thought too hard about what I was taught to see if it really made any sense. One day, though, I was on wikipedia and was curious as to the entry on JWs. I read a lot of history there that I never had heard of before. Most importantly, it was backed up by quotations taken from the society's publications. As well, it cross-matched with the Proclaimers book, but did not gloss over the less glamorous aspects of the history. I thought about some of the things in our history, and I decided to "make the truth my own" and convince myself of the teachings that I had always accepted at face value all my life.
I also prayed to God to help me know if I was really in the true religion. Don't know if it's coincidence, but that very week The KM article came out strongly discouraging getting together in a group to study the Bible independent of WT publications. That didn't make much sense to me since the scriptures say that if 2 or 3 christians meet together that Jesus would be in their midst. I decided that if we REALLY have the truth, then it can stand up to outside scrutiny.
So I started to research. Although I confirmed that there are JW teachings that I feel are solidly grounded in the Bible, I was rather disturbed to find many official teachings that conflict with the scriptures, history, and science:
- The "Global" flood of Noah
- Dissallowance of blood transfusions
- Allowing fractions that come from disallowed blood
- Dead witnesses because the spirit-directed organization incorrectly disallowed organ transplants
- Jesus is Michael
- 607/1914
- That I am dooming people to death if I talk to them about the Kingdom but they don't believe me
- The spirit-directed governing body deciding important scriptural matters by means of a vote
- Double standards in regards to freedom of religion
- Meaning of the "other flock" and "last days" (in conflict with what the 1st C. Christians understood them to be)
- Not allowing scriptural discussion different from official teachings. Testing the "inspired expressions" does not apply to the "Faithful Slave".
- Putting down other christian groups for failed predictions, but calling own failed predictions "eager expectation"
- Requiring us to accept the latest "scriptural refinements" as truth whether or not they make sense. Overuse of the word "evidently" (evidently means "well it's evident that we were wrong, so let's change our understanding to fit the evidence")
- The generation changes, destruction of Sodom and Gomorrah flip-flops (Why does the spirit keep changing what is "true", unless of course it's perfect men taking their best guess based on what they know at the time)
- That the generation, anointed and faithful changes were all clearly made necessary to circumstances showing that the previous understandings were incorrect (as opposed to spirit guided "new light")
- The annointed as the mediator between the "other sheep" and the mediator Jesus Christ
- That the entire book of Revelation is symbolic expect for the number of the 144,000 (Plus there were more than 144,000 Christian martrys in the 1st C).
- That the Bible's reference to Abraham, Issac, and Jacob in heaven doesn't really mean they're in heaven.
- Pinatas and wedding rings are okay because even though they have false religious backgrounds they're not viewed as such today, but toasting is bad because "maybe" it has false religious background
- Shunning of disfellowshipped ones (Similar to how the Scribes and pharisees treated other Jews as "amharets". Why do the interpretation of Paul's words take precedence over Jesus teaching to treat a brother who has left as a tax collector and a harlot. Jesus ate with the tax collectors and harlots and try to bring into the christian fold?)
- Not allowing bestiality and homosexuality as ground for divorce for a long time (spirit-directed?)
- Dictating sex policies between married individuals with no scriptural backing
- Not providing references for quotes in publications (when I started to look up the individuals or articles quoted, I saw why. They were from "false religious" sources, or the quotes were taken out of context)
- Calculating when the end would arrive even though Jesus said that no one knows the day or hour but the Father
- That we serve God out of love, but almost every single public talk ends with "If you want to live forever on earth then you need to do this"
- Non-biblical definitions of faith/spirituality (X hours of field service, meetings, commenting, preparing for meetings, etc)
The list continues to grow... During this whole time I honestly wanted to discover that the JW teachings are really the truth, but I just cannot come to that conclusion.
