The Dudleian lectures are a series of prestigious lectures on religion at Harvard University, where they are the oldest endowed lectureship. They have been given every year from 1755 to the present. The lectures were endowed by Paul Dudley in 1750 with a sum of £133 6s 8d. Dudley specified that the topic of the lectures should rotate among four themes, so that students would hear each one before graduation:
- The principles of natural religion.
- The truths of scriptural revelation.
- "The detecting and convicting and exposing the idolatry of the Romish church, their tyranny, usurpations, damnable heresies, fatal errors, abominable superstitions, and other crying wickedness in their high places".
- "The validity of the presbyterial ordination of ministers" (specifically, in the form practiced at the time in Scotland and Geneva, and among Englishmen who opposed the episcopal ordination of the Church of England).
In accordance with these precepts, the Dudleian lecturers of the 18th century did faithfully promote the doctrines of New England's anti-authoritarian Low-Church Protestantism, and — as L.K. Gilbert argues — wedded them to principles of Enlightenment rationality by associating ecclesiastical with civil tyranny.
By the 19th century, however, the virulent anti-Catholicism had been much tempered, and in the middle of the 20th century, Clifford K. Shipton could note that "for many years past it has not been deemed expedient by the college authorities to honor the donor’s wishes in this respect." Contemporary Dudleian lectures tend to be highly academic in nature, and are often delivered by Catholic or non-Christian theologians or priests. In a more ecumenical, less religiously polemical age the third topic has been reinterpreted to intend relations among the Christian denominations: The first Catholic who gave the Dudleian lecture under this rubric was Fr. Henri Nouwen.
