Very true. Every religion is made up of both Theology and Ritual/Practice. The Theology is what they claim to believe and the Ritual/Practice is the means through which they show their piety.
When one looks at the theology of a large number of the religions, there are a great number of common ideals and values espoused. They claim to want Peace, Health, Law & Order, etc.... and to be against Theft, Rape, Murder, et al.... The problem comes that there's always a caveat, an exception, etc.... Live in peace with everyone (Except THOSE guys. It's okay to rob, cheat, steal, murder, rape THOSE people because WE'RE the Chosen Ones and they aren't). It's hypocritical and obviously so, if one takes a step back to look at it; and no religion/theology is truly free from that form of thinking. They've all been on both sides of the equation for thousands of years.
Why does every wolf pack have an Alpha, a Beta and an Omega? Why do herds of wild horses follow the lead Stallion and Mare? Why do salmon swim upstream to mate every year? Natural Instinct and Order. They were made that way for a particular reason and nature has maintained these social and instinctive traits for thousands of years. It is only humankind which believes it knows better than The Universe how things should work. We're the only species that I'm aware of that actively goes out of its way to ignore our instincts and nature at almost every single turn. Those instincts and nature ARE the basis for Universal Morality. Human beings learned to live together in a certain way, with certain roles, rules, and instinctive knowledge sharpened against nature's sharper edges. Then we became "Civilized" and have now thrown most of that knowledge away, to our detriment.

No problem. I'm not 100% certain that I can explain it fully through this medium. I'm a much better verbal communicator than a writer.
