Pope Francis has appointed Fr Kevin Doran as Bishop of Elphin.
Fr Doran is Administrator of the Parish of the Sacred Heart Donnybrook in Dublin. He was born in Dublin in 1953 and was ordained a priest in 1977.
In October last year he resigned from the board of the Mater Hospital after management confirmed it would comply with the new Protection of Life During Pregnancy Act.
At the time Fr Doran said he had resigned because he could not reconcile his conscience with the statement largely because he felt a Catholic hospital had to bear witness to gospel values alongside providing excellent care.
Speaking about his appointment, Fr Doran said he was "a little surprised" as two weeks ago the only plan he had for the foreseeable future was the development plan for his parish.
However, he said he has learned over the years that "vocation is never static".
Fr Doran remarked that "the bishop is not called to be a 'lone ranger'.
"The service of communion includes recognising the diverse gifts which the Spirit has given to everyone in the community of the diocese, religious, clergy and members of the lay faithful, and making it possible for those gifts to be developed and placed at the service of all."
Archbishop Diarmuid Martin congratulated Fr Doran on his appointment.
He paid tribute to Fr Doran's work as General Secretary of the 50th International Eucharistic Congress and for "his great organisational skills in making one of the largest recent events of the Irish Church such a success."
