Archbishop William Lori of Baltimore, chairman of the United States Conference of Catholic Bishops’ Committee on Pro-Life Activities, preached the homily (full text) at the National Prayer Vigil for Life at the Basilica of the National Shrine of the Immaculate Conception in Washington.

During the Mass, a pro-abortion advocacy group projected messages onto the National Shrine’s facade and bell tower. A spokesman for the organization said it had secured a city permit to do so.
