The Most Reverend Ronald W. Gainer, Eleventh Bishop of Harrisburg, announced that Pope Francis has named His Excellency, the Most Reverend Timothy C. Senior, as the Twelfth Bishop of Harrisburg. Bishop-designate Senior succeeds Bishop Gainer, who, in keeping with canon law, offered his resignation to the Holy Father when he turned 75 years of age in August of 2022. Bishop Senior’s Mass of Installation will be at 2 p.m. on Wednesday, June 21, 2023, at the Cathedral of Saint Patrick in Harrisburg.

“This is a joyous day for our clergy, staff, the people of the Diocese and for me personally. I have known Bishop Senior for well over 25 years and have full confidence that he will be a caring, faithful shepherd who will speak the truth with love and conviction, leading the Diocese of Harrisburg with the truths of the Church as a witness of Jesus Christ,” said Bishop Gainer. “I am grateful to our Holy Father in sending the Diocese of Harrisburg a man devoted to answering the call of the Gospel, who also has numerous skills in business, education, and human service administration. The Diocese of Harrisburg will be well cared for in the hands of Bishop Senior.”
