The official statement of Unitarian Universalist principles describes the "sources" upon which current practice is based:
- Direct experience of that transcending mystery and wonder, affirmed in all cultures, which moves us to a renewal of the spirit and an openness to the forces which create and uphold life;
- Words and deeds of prophetic women and men which challenge us to confront powers and structures of evil with justice, compassion, and the transforming power of love;
- Wisdom from the world's religions which inspires us in our ethical and spiritual life;
- Jewish and Christian teachings which call us to respond to God's love by loving our neighbors as ourselves;
- Humanist teachings which counsel us to heed the guidance of reason and the results of science, and warn us against idolatries of the mind and spirit.
- Spiritual teachings of earth-centered traditions which celebrate the sacred circle of life and instruct us to live in harmony with the rhythms of nature.
