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, Buddhist, and Humanist clergy. The letters make reference to points raised by intelligent design proponents. There are five separate letters: A Christian Clergy Letter, a Rabbi Letter, a Unitarian Universalist Clergy Letter, a Buddhist Clergy Letter, and a Humanist Clergy Letter. As of October, 2022, there were 15,679 signatures from Christian clergy, 839 signatures from Jewish rabbis, 688 signatures from Unitarian Universalist clergy, 75 signatures from Buddhist clergy, and 58 signatures from Humanist clergy.
