“Islam and World Christianity” will be the topic of a lecture Wednesday by a Yale University history professor at Greenfield Hill Congregational Church.

The program, which is free, is set for 7:30 p.m. in the church, 1045 Old Academy Road.

Lamin Sanneh, the D. Willis James Professor of Missions and World Christianity at Yale, will be the speaker.

The Rev. David Rowe, of Greenfield Hill church, in a statement publicizing the lecture, said, “I first studied Islam under Dr. Lamin Sanneh at Harvard 30 years ago. He was a brilliant and engaging teacher.

“An excellent writer, and renowned scholar, he is highly regarded within the world of Islam, and in the world of interfaith and ecumenical dialogue. Dr. Sanneh brings respect and integrity to the subject, enriched by his own faith journey,” Rowe added.

Sanneh is a fellow of Trumbull College at Yale. He was appointed by John Paul II to serve on the Pontifical Commission of the Historical Sciences at the Vatican and by Pope Benedict XVI to the Pontifical Commission on Religious Relations with Muslims, according to Greenfield Hill church.

He is the author of more than 200 articles in scholarly journals and of more than a dozen books on Islam and Christianity. He is series editor of the multivolume “Oxford Studies in World Christianity,” and the co-editor of the “Wiley-Blackwell Companion to World Christianity,” to be published next spring.
