On the same day Pope Benedict XVI gave his final Sunday blessing, Philadelphia Archbishop Charles Archbishop Chaput will hold an evening mass at Cathedral Basilica of Saints Peter and Paul.
The mass, which begins at 6:30 p.m., will be held to celebrate the ministry of Pope Benedict XVI, the Philadelphia Archdiocese said.
Thousands attended the Pope's Sunday blessing at the Vatican. Local police estimated the crowd to be 10,000, the Associated Press reports.
On Thursday, Pope Benedict XVI will become the first pope to have resigned from the papacy in centuries.
