People forget that words are a symbol that we use to represent reality, not the actual reality itself. Everybody forgets this especially when it comes to religious matters. Anyway that you describe God, or describe the ultimate nature of the reality we experience falls flat, because it is simply a symbol rather than the actual reality. To take religious texts absolutely 100% seriously is to forget the fact that words are a symbol. Personally I like the example of equating these symbols to a finger pointing at the moon, but instead of looking up and seeing the actual moon, you suck the finger pointing to it, aka you put the words on a pedestal and revere the words all the while forgetting words are a symbol, not the actual reality itself. Another example of being bamboozled by words is the climate change crowd, if the weather deviates from how it is "supposed to be" during a certain "season", then it represents something bad that needs to be somehow changed. Yet once again they are forgetting that in reality there are no "seasons" it is once again, a symbol, sure we can get extremely convincing asserting that seasons are real, but in the end its still just words. This isn't saying that God doesn't exist, or that X religion is true while X religion isn't, it is simply pointing out that words are a symbol, no matter how much we prostrate ourselves before the written word, it will always just be words, and their "authority" will always come from you (you in a broad sense) who believes the word.

Mainly my point is this: don't get so caught up in the words of religious texts, whether it's the Bible, Quran, Upanishads, etc. The words all point to actual reality, an experience, and most people tend to focus 100% on the words, the symbol, rather than the reality these words point to. Words, no matter who speaks them, no matter who writes them, no matter how convincing they are, no matter how many people believe them, will always just be words.
