I came up with this a few years ago and still like it a lot. If I had been thinking, I would have used it as my blog's first post:
I believe in one God: a Force omnipotent, omniscient, omnipresent and eternal, that created the universe and all that is in it, that sustains all, that permeates all, that transcends all.
I believe that while the full nature of the transcendent God is beyond our comprehension, God’s presence is manifest in love, compassion, truth, justice, harmony, and beauty, and is further revealed through worship, study, and contemplation. I believe that devotion to these develops the element of God present within each of us, and in so doing, binds ourselves more closely to God.
I believe that God is opposed by Evil: a lesser, yet likewise omnipresent and transcendent, Force, that seeks the corruption of God’s works and purposes, and that exploits the limitations of human nature through undetected cunning, falsehood, and deception. I believe that Evil prospers parasitically, by manipulating the power of God to its own ends, and withers when it is recognized and isolated from God’s vital, sustaining strength. I believe it is our sacred duty to learn to recognize and resist the many subtle guises of Evil.
I believe that God created Earth to sustain life, that the presence of God infuses all life and all creation, and that the land, air, water, natural systems, and wild places of Earth, being of God and with God, are sacred to God and mankind.
I believe that in diverse times and places diverse societies receive insight into the nature of God; that these disparate insights are both uniquely informed and uniquely constrained by cultural and historical context; that each of these distinct insights nevertheless contains a valid apprehension of the one transcendent God; that the differences among them, arising out of perception and not substance, are illusory; and that as these many experiences compound over the course of human history, a deeper, richer relationship with God becomes available to successive generations.
