Perhaps the greatest disagreement about the meanings of religious words involves the word "Religion:"
Many people have their personal favorite definition of "religion." Unfortunately, there no thing approaching a consensus exists. Many people firmly hold their own definition to be absolutely correct, and believe that those held by everyone else are false.
Many definitions of religion contain a requirement for belief in one or more deities. If belief in at least one God or Goddess is to be a requirement for a religion, then Buddhism would not be considered a religion. Yet it is always included as a major religion in books and articles about the religions of the world. It is considered the fourth most popular organized religion on Earth, after Christianity, Islam and Hinduism. In addition, requiring a belief in deity/deities would eliminate Unitarian Universalism (a.k.a. Unitarianism) as a religion, because they do not require such a belief among their members.
Our web site's difficulty with governments over the definition of religion:
Back in the 1990's, during the infancy of the Internet, this web site was evolving from a personal hobby to a registered Canadian organization. We attempted to have the group recognized as a non-profit charity. That would allow us to issue tax exemption certificates to Canadian donors. We were refused because the Government of Canada's definition of "religion" required religious non-profits to teach the belief in the existence of a God.
Any God would do: Yahweh, Allah, Jesus Christ, Aphrodite, Artemis, Astarta, Athena, Baal, Bast, Diana, Venus, Zeus, etc. In spite of this restriction, the federal government registered -- and still registers -- Buddhist and Unitarian groups as non-profits. But it would not recognize our web site as religious. Go figure!
So, we registered our group as a "for profit" entity. Even then, we ran into problem with definitions. We initially registered as Ontario Center for Religious Tolerance. This was rejected by the Ontario Government because the word "Center" in a company name can only be used in that province if the organization is a registered charity. So we changed our group's name to "Ontario Consultants on Religious Tolerance." This was not a great name, because we don't do consulting work. But we were finally able to register, and thus obtain a bank account.
A recommendation from the Webmaster:
Please give other people some slack. When you disagree over the meaning of a religious word, please consider that there may not be a universally held meaning. Perhaps it is OK for people to hold diverse understandings.
Please try to put things in perspective. You probably hold many beliefs in common. Try to get along.
If you are ever in the Netherlands, please considering visiting with the Pastafarians at the newly recognized Church of the Flying Spaghetti Monster. News came of this Church's government registration as I was updating this essay.
