Every culture and religion in the world no matter where it maybe, can be a far away city in China or South american indians in the Amazones, ALL religions or group of civilizations believe in ONE GREAT FORCE, they may called it GOD, OR SUPREME BEING or whatever other name. They know there is something 'bigger' above than the human being.
I have to agree, one all powerful being is the center of nearly every religion. Maybe not so much as a being, but a force, a presence, something greater than ourselves. Wiccans believe in the goddess, and the power and forces in nature. Hindus believe in an all powerful being, buddhists believe in a universal collective of peoples spirits. Monotheistic religions believe in a singular god. But all of them believe, ultimately, in a higher power, something greater than ourselves individually, even if that god is within ourself.
This is a very interesting topic for me to see. Just this morning I had two lovely women come to my door that were Jehovah's Witnesses. As I answered the door, they wanted to read to me from The Watchtower and as I am genuinely interested in other religions, I wanted to hear what they had to say. I am always polite and respectful when people of other religions visit. (partly because my parents were not, but that is another topic I've touched before) When they asked me if I attended church, I told them yes, that I am a Latter Day Saint and they said, "Well, the one thing we have in common is the Bible." And I thought this was an interesting thing to say. I said, "We do have other things in common too." But, she really didn't want to speak anymore with me, which I thought was very sad. She asked if the other people in my building were home and I told her that they were not and she wanted to leave very quickly. That made me sad, but I am also used to it. I don't know how much relevance this story has, but it was what the woman said that struck me as so on-topic to JB's title.
I have to disagree with the idea that all religions believe in a single, all-powerful force. The only major example I can think of in the modern world is Confucianism, but spiritualities centering around animism, ancestor-worship or local panoplies of deities still exist across Africa and India and such religions seem to once have been the norm.
I would conjecture that almost all religions share the basic respect for humanity demonstrated by the almost ubiquitous golden rule of "Do unto others as you would have them do unto you."
There are a small number of religions following racist principles who would reject this rule and one not based on religious principles: LaVey's Satanism.
I agree, Yiab. There are also plenty of people around the world of various traditions who are hard polytheists, meaning they believe in/experience the Gods as separate beings or forces rather than as archetypes or as facets of one higher being or force. I wish the one thing we all had in common was the Golden Rule or Wiccan Rede, but religious belief and experience is much more varied and nuanced than most of us ever realize.
