Some Unitarian Universalists are nontheists and do not find language about God useful. The faith of other Unitarian Universalists in God may be profound, though among these, too, talk of God may be restrained. Why?
The word God is much abused. Far too often, the word seems to refer to a kind of granddaddy in the sky or a super magician. To avoid confusion, many Unitarian Universalists are more apt to speak of “reverence for life” (in the words of Albert Schweitzer, a Unitarian), the spirit of love or truth, the holy, or the gracious. Many also prefer such language because it is inclusive; it is used with integrity by theist and nontheist members.
Whatever our theological persuasion, Unitarian Universalists generally agree that the fruits of religious belief matter more than beliefs about religion — even about God. So we usually speak more of the fruits: gratitude for blessings, worthy aspirations, the renewal of hope, and service on behalf of justice.
