"He very generously accepted a very difficult task in Rome, where he ended up spending a much longer time than he had anticipated. He did everything that the Church asked him to do. He has responded with great generosity, and we all know of his talent, and work ethic, and his love for the Church," the cardinal said.

The cardinal then presented Bishop Deeley with a set of vestments to be used at his Mass of installation.

In his homily, Bishop Deeley said he appreciated the trust Pope Francis has placed in him by asking that he lead the Diocese of Portland.

He also explained that he had planned this local Mass of Thanksgiving when he learned that space for visitors at his Feb. 14 installation Mass would be limited because so many of his new flock wanted to be present to welcome their new bishop.

"They said that the priests and the people of Maine really wanted to participate in the Mass themselves; they have been 20 months without a bishop and they are interested to get to know the one the Holy Father has sent to them," Bishop Deeley said.

He said that as he drove back from the January press conference to announce the appointment, "I got a call from one of my Irish cousins informing me that they were organizing a group to come over, so I figured I really had to do something," Bishop Deeley.

"I am very grateful that Cardinal Seán suggested graciously that we have this Mass today, to which I was able to invite the many people who have been part of my life, and part of my ministry in Boston, over these last 40 years of my priesthood, to come to join me and give thanks to God for all the ways in which he has blessed my life through the great privilege of being a priest in Boston," he said.

After he thanked all those present -- including members of the Order of Malta, whom he serves as a deputy chaplain -- he concluded with a simple request.

"May God bless you all and your goodness to me, in the numerous ways in which you have shown me God's love. Please keep me in your prayers," Bishop Deeley said.

Speaking to The Pilot after the Mass, Bishop Deeley's oldest brother, Paul Deeley, said the appointment is a great honor for the bishop.

"I think it is a confirmation of his abilities and his dedication to his work, his mission, over the past 40 years," Paul Deeley said.

His younger brother, Father Kevin Deeley of St. Michael Parish in North Andover, said Bishop Deeley maintained the simple demeanor of the parish priest throughout his service to the Church.

"He's a consummate parish priest. So, of all the abilities he has as an administrator, working in the Vatican, working in the archdiocese, at the heart he is a great parish priest. He knows how to respond to the needs of people when they are celebrating the birth of a child, the death of a parent, first Communion, confirmation. That's at heart who he is as a priest, and that's what we all do as priests is serve the people. All of this other stuff is needed to organize the Church, but at the heart, at his heart, he is a parish priest," Father Deeley said.

Chair of the Order of Malta in Massachusetts Damien DeVasto said the Mass was a fitting send-off for Bishop Deeley.

"The cardinal's words were heartfelt, and to see so many of Bishop Deeley's brother priests, his family and friends come together at this celebration made the Mass a wellspring of good feeling, and a special way to give thanks to the bishop for his remarkable leadership," DeVasto said.

"It was wonderful that we were able to come together in this special celebration, to give Bishop Deeley thanks for his remarkable leadership in Boston and to reinforce that he has our prayers and support as he shepherds the people of Maine," he said.
