The lawsuit filed Wednesday in the city's Court of Common Pleas says the man was assaulted as a boy by a priest from St. Francis Xavier parish and Roman Catholic High School in Philadelphia.
The plaintiff says archdiocese officials put him in harm's way when they concealed their knowledge of the Rev. John Kline's previous offenses.
It is the third such lawsuit since last month's grand jury report led to criminal charges against three priests and a high-ranking archdiocese official charged with failing to protect children from predator priests.
