Robert McAfee Brown, professor of Religion at Stanford University, will deliver the William Belden Noble lectures Monday through Thursday of next week. The four lectures, entitled "The Ecumenical Revolution," will deal with changing attitudes within the Protestant and Catholic Churches.

Brown, a member of the United Presbyterian Church of America, is the author of An American Dilogue, a collection of essays on contemporary Protestant-Catholic debate. His "Writings of St. Hereticus," a series of magazine articles, have parodied the pretensions of American Protestantism.

Brown will preach at the 11 a.m. Easter service in Memorial Church.
