BRAINTREE -- Rectors of two seminaries within the Archdiocese of Boston have been chosen by Pope Benedict to become auxiliary bishops of the archdiocese -- a move that is regarded as significant by many in the archdiocese.

"The fact that we have two new bishops who are coming out of the world of priestly formation I see as a very special help as we try to deepen the ongoing formation of all our clergy," said Cardinal Seán P. O'Malley at a June 30 press conference announcing the new bishops.

"One of the things I've been talking about is the need for us to continue our theological studies and have priestly fraternity based pretty much on a shared life of prayer and spirituality," the cardinal continued.

At the press conference held at the archdiocese's Pastoral Center, Cardinal O'Malley announced that Fathers Arthur Kennedy and Peter Uglietto have been raised to the rank of bishop by the pope. Bishops-elect Kennedy and Uglietto will become the 34th and 35th auxiliary bishops of the archdiocese at their ordinations Sept. 14 at the Cathedral of the Holy Cross.

At the same press conference, Cardinal O'Malley announced that the Holy Father has accepted the resignation of Bishop Emilio Allue, 75, who retired due to age reasons.

Bishop-elect Kennedy, 68, will remain as rector of St. John's Seminary in Brighton.

Bishop-elect Uglietto, 58, will move from rector of Blessed John XXIII National Seminary to bishop of the archdiocese's north region, effective following his ordination. He will be replaced at Blessed John by Father William Palardy, currently the academic dean of Blessed John.

Bishop-elect Kennedy announced that his Episcopal motto will be "Ut congnascant Te," Latin for "That they may know Thee," which was also the motto of Cardinal Richard Cushing. Bishop-elect Kennedy said he took his motto to honor the memory of Cardinal Cushing, who was archbishop when he was a seminarian at St. John's Seminary in the early 1960's.

Bishop-elect Uglietto, meanwhile, said he has not selected his motto yet, although he is weighing some options.

In their remarks at the press conference, both bishops-elect discussed the importance of preparing priests for service to the Church.
