Liberal theism is the philosophical and religious belief in the existence of a deity without adhering to an established religion. The exact definition is debatable. Liberal theists often believe that, "all religions lead to the truth." Liberal theists are often influenced by the beliefs in their culture. For example, a liberal theist in the United States is likely to have beliefs strongly influenced by Christianity. It can also be said that all religions began as a form of liberal theism. Liberalism can also exist in established religions, such as Christianity, Judaism, or Islam.
