An excellent summary of Jefferson’s theology is in Robert M. Healey, Jefferson on Religion and Public Education (New Haven, CT: Yale, 1962); on the Bible, see pp. 102–104: on clergy, pp. 105–107, 118–119. The best of many versions of his work on the Gospels is Dickinson W. Adams, ed., Jefferson’s Extracts from the Gospels: ‘The Philosphy of Jesus’ and ‘The Life and Morals of Jesus,’ in the Second Series of The Papers of Thomas Jefferson (Princeton, NJ: Princeton Univ. Press, 1993).
