The Clergy Letter Project is a project that maintains statements in support of the teaching of evolution and collects signatures in support of letters from American Christian, Jewish, Unitarian Universalist, and Buddhist clergy. The letters make reference to points raised by intelligent design proponents. There are four separate letters: A Christian Clergy Letter, a Rabbi Letter, a Unitarian Universalist Clergy Letter and a Buddhist Clergy Letter. As of August 12, 2013, there were 12,878 signatures from Christian clergy, 503 signatures from Jewish rabbis, 273 signatures from Unitarian Universalist clergy and 23 signatures from Buddhist clergy.
