A Yale University ethics expert will speak on Christian concepts of dignity Friday evening, Oct. 5 at Saint Luke Church.

The lecture by Frederick Simmons is planned at 8 p.m. and is free and open to the public, the church said.

An assistant professor of ethics, Simmons has a master's of divinity degree and Ph.D. from Yale. His topic will be "Christian Conceptions of the Nature, Sources and Moral Significance of Human Dignity."

Simmons' presentation will be preceded by a wine and cheese reception at 7:30 p.m. The talk is the first in a series of five First Friday Lectures at the church.

Simmons' research and teaching examine the moral implications of Christian theological commitments and the relationships between philosophical and theological ethics, St. Luke said in a news release. He is completing a book on the significance of ecology for the ethics and potential salvation of Christians. He also is co-editing a volume on love and Christian ethics.

Saint Luke Church is at 49 Turkey Hill Road North.
