Quakerism and Pantheism seem like a natural fit to me. The fundamental idea of Quakerism is that of God in everyone. In Quakerism, we serve God by treating all people with love. Pantheism just extends that to the universe. Not only do we treat all people with love, but we also care for the environment. For me, there is no external heaven or afterlife, it's all right here, right now. The world is a wondrous place.
