Dr. Maggie McGuinness of La Salle University will speak on St. Katharine Drexel and the ministry of the Sisters of the Blessed Sacrament in Philadelphia’s African-American neighborhoods on Sunday, Sept. 17 at 2 p.m. at the American Catholic Historical Society located at 263 South 4th Street in Philadelphia’s Old City section.

McGuinness, who is currently writing a biography of St. Katharine Drexel, will discuss how the work of St. Katharine and the Sisters of the Blessed Sacrament in urban neighborhoods opened a new chapter in the history of a religious community originally founded to evangelize in far-off corners of the United States.

The talk is free and open to the public.
