PITTSBURGH — The Diocese of Pittsburgh has announced a special “Service of Apology” in the wake of two Catholic bishops who covered up years of sexual abuse by religious leaders in the Altoona-Johnstown Diocese.

Bishop David Zubik announced that he will lead the service at 7 p.m. March 21 at Saint Paul Cathedral in Oakland.

“It (service) is a moment for me as Shepherd of this local Church to say those three very important but oft forgotten words, 'I am sorry,' and in so doing to seek forgiveness of anyone hurt by the Church,” Zubik said in a statement.

A grand jury issued a report Tuesday that the two bishops, Joseph Adamec and James Hogan covered up the sexual abuse of hundreds of children by over 50 priests and religious leaders over a 40-year period within the Diocese of Altoona-Johnstown.
