Answer: D. any sacred text
Step-by-step explanation:
Although both Unitarianism and Universalism come from the Protestant Christian tradition, which upholds the Bible as the sacred text, Unitarian Universalists no longer consider the Bible, not any sacred text, to be infallible nor the only source of truth. The Qur'an, Vedas, Bhagavad Gita, Dhammapada, and Tao Te Ching are all sacred texts for them, and at the same time, they acknowledge that they are a product of their time and place, and are open to interpretation.
