 Theodore Parker (1810–60) was the son of a farmer who attended Harvard and became a Unitarian minister and accomplished linguist. He published a long critical essay on David Friedrich Strauss’s Das Leben Jesu, and translated Wilhelm Martin Leberecht de Wette’s Introduction to the Old Testament, both of which cast doubt on the divine inspiration and single authorship of the Bible. After the publication of his “A Discourse Concerning the Transient and Permanent in Christianity” (1841) he was invited to resign from the Boston Association of Ministers (he did not), and was no longer welcome in many pulpits. He argued, much as Emerson had in the “Divinity School Address,” that Christianity had nothing essential to do with the person of Jesus: “If Jesus taught at Athens, and not at Jerusalem; if he had wrought no miracle, and none but the human nature had ever been ascribed to him; if the Old Testament had forever perished at his birth, Christianity would still have been the Word of God … just as true, just as lasting, just as beautiful, as now it is…” (T, 352). Parker exploited the similarities between science and religious doctrine to argue that although nature and religious truth are permanent, any merely human version of such truth is transient. In religious doctrines especially, there are stunning reversals, so that “men are burned for professing what men are burned for denying” (T, 347).
