Clergy members from different traditions continue to attach their names to The Clergy Letter Project, which hopes to demonstrate that science and religion are complementary and that Christians can believe in evolution. "Religious truth is of a different order from scientific truth. Its purpose is not to convey scientific information but to transform hearts," reads part of the two-paragraph clergy letter. "We urge school board members to preserve the integrity of the science curriculum by affirming the teaching of the theory of evolution as a core component of human knowledge. We ask that science remain science and that religion remain religion, two very different, but complementary, forms of truth." The clergy are also encouraging other religious leaders to celebrate Evolution Weekend, February 8 through 10, and to take the time to deeply explore the nature of science and religion. —Heather Wax
