Why should one book hold the answer to everything? People have backed up this with it's God/Allah or whoever's word but I am a firm believer in logic and reasoning so you could say I am an atheist.
Logic and reason can be a means that often leads a person to atheism given how illogical and unreasonable religion often is. However this in itself does not make you an atheist. Simple question do you believe god (any gods) exist? If no, then your an atheist. If you do then you're a theist.
But I have always been a firm believer in religion. Taking Holy Books liberally (taking the meanings of stories rather than taking them as if they happened) I believe that you should read all of the Holy Books and then decide for your self what you believe in.
As a theist I saw how each religion didn't have the right story. I still believed religion had truth to it. So I thought perhaps each one held a piece of the truth and it was just a matter of putting it together. The result is no better then any one religion.
Though I will agree learning about as much as you can, even religion, is good to do.
Also while I will agree that a person is entitled to their beliefs and opinions, they are not however entitled to their own truth.
You don't even need to read them, our morals are so intertwined with religious morals nowadays you can literally look in the Bible, Torah etc. and find the stories that teach these morals.
actually it's sort of the other way around. Religions took these concepts that were already present and required for societies to exists and incorporated them into themselves. Adding the requirements of mindless worship.
Belief shouldn't stick to one type of faith; you can take morals from any religion and make your own choices.
Belief shouldn't stick to any faith, that can just be gullibility. You don't need religion to get morals, as noted religion hijacked morality and even corrupts it as times.
