(AP) — In a Lincoln speech, a Yale law professor will discuss efforts to patrol the wall of separation between church and state.

Stephen Carter’s lecture is titled “The Current Situation in Church and State.” It is scheduled to begin at noon Friday in Hamann Auditorium at the University of Nebraska-Lincoln. The event is free and open to the public.

Organizers say Carter will review recent developments and explain how a greater attention to history and game theory will help people gain a richer understanding of how and why to protect the wall of separation.

Carter has taught at Yale since 1982. Among his books on law and politics is “God’s Name in Vain: The Wrongs and Rights of Religion in Politics.”
