Took a number of classes in college on Judaism/Torah/Pentateuch, one of them was a Dead Sea Scrolls class. Now that's some interesting shit. All that said though, I will admit I am not a big fan of organized religion myself as its too easy to control the interpretations.
Take for instance the Islamic view that Allah and the Christian/Jewish God are the same. I buy it. Muhammed gives a constant nod to "the people of the book" and also admits that (while not the messiah) Jesus was a very important prophet (if not the most important). Many terrorist muslims may ignore these passages or focus on the ones where it is considered acceptable to kill "people of the book", which is an interpretation that militant clerics will focus on. As well, most evangelical christians (and possibly most christians period) don't recognize this, many probably would have a scanner moment before they excepted it.
Which, from where I stand, is choosing to ignore a lot of history about the development of the Christian/Jewish God. He didn't just appear from nowhere. Yahweh was a Sumerian diety first. This means that Christians and Jews worshipped the same God as Sumerians. You could argue that since the Sumerians didn't worship Yahweh monotheistically they misunderstood his essence, true, but that same argument could be applied to Islam. They also worship the same God, just with a different interpretation.
And these superficially strong differences in interpretations can cause division between groups that have historically acknowledged their relationship as worshiping the same God, and are maintained by organized religions that focus on building painfully detailed interpretations and sets of rules like Hallawah and Shariah etc. as though they will further cement what is effectively a best guess on an impossible question.
TLDR, I'm a Taoist. Everyone's on a right path but its impossible to get to all the way to the Truth. Christians and Jews and Muslims and Hindus and Taoists and Universal Field Theorists are all headed to the same point, but from different directions. When it seemed that they couldn't get closer they set up tents and started laying out fortresses of interpretations and laws and looked at the other guys and said "Hey, that's a crappy place to build an ideology. Bake em away toys".
Having problems putting this into words, but....that's why I am Taoist (who, by the way, can fuck it up with the best of them. All you have to do is look at the retarded pantheon that they came up with to see how organization completely ruined that religion can get. I still don't understand how in the world Taoism can even have a pantheon.)
