Peter John Uglietto
Peter John Uglietto was born in Cambridge, Massachusetts, on September 23, 1951, the son of Salvatore and Dolores Uglietto, and grew up attending Saint Luke parish school and the Boston Archdiocesan Choir School before Boston College High School. He graduated from Boston College in 1973 with a bachelor's degree, then entered Saint John Seminary in Brighton, where he earned a Master of Divinity in 1977. Music, study, and parish life in his home city shaped the priest he became.
He was ordained a priest on May 21, 1977, and served as an associate pastor in South Weymouth and Dorchester, directed the archdiocesan permanent deacon program, and worked in campus ministry at Regis College in Weston. He pursued further study at the John Paul II Institute in Washington, earning a licentiate and a doctorate in sacred theology from the Pontifical Lateran University, then joined the faculty of Pope Saint John XXIII National Seminary in Weston, where he was academic dean and, from 2005, rector and president.
Pope Benedict XVI named him an auxiliary bishop of Boston on June 30, 2010, and he was consecrated on September 14, 2010, at the Cathedral of the Holy Cross. He served as regional bishop for the North Region and, from March 6, 2014, as vicar general and moderator of the curia, a post he held until Bishop Mark O'Connell succeeded him on January 1, 2023. He remains an auxiliary bishop, formed above all as a seminary rector and spiritual director for priests.
- 2021-07CONTEXT, NOT UGLIETTO'S ACT: Catholic News Agency reports Boston among the archdioceses allowing priests already celebrating Mass according to the 1962 Missal to continue doing so. The position belongs to the then ordinary, Cardinal Sean O'Malley. Uglietto was vicar general at the time, but no act or statement by him on the matter was found, and a vicar general's office alone is not credited as his governing act here. ↗
- 2026-10-24INHERITED PROVISION, NOT UGLIETTO'S ACT: Mary Immaculate of Lourdes, Newton, lists Traditional Latin Masses on Sundays at 11:00 a.m. and 5:30 p.m. and names the extraordinary form as the 1962 Missal. No act by Uglietto concerning the parish was found. ↗
<p>Bishop Uglietto has no governing act of his own on the 1962 Missal in this dossier, and none is invented for him. That verdict needs care, because he was vicar general and moderator of the curia from March 6, 2014, to January 1, 2023, covering the whole first eighteen months of the Traditionis custodes era, and a careless file could credit the archdiocese's continuation position to him by office alone. No diocesan statement, decree, permission, appointment, or public letter by him concerning the older Missal was found in archdiocesan releases, The Boston Pilot, or national coverage searched on October 24, 2026, so the office is not credited as an act.</p>
<p>What Boston does have is inherited provision, and it is described as inherited, not as his work. In July 2021 Catholic News Agency reported Boston among the archdioceses allowing priests already celebrating Mass according to the 1962 Missal to continue doing so, a position taken under Cardinal Sean O'Malley, who was then archbishop. The one site evidenced as currently operating under the 1962 Missal is Mary Immaculate of Lourdes in Newton, whose parish site, fetched October 24, 2026, lists Traditional Latin Masses on Sundays at 11:00 a.m. and 5:30 p.m. and names the extraordinary form as the 1962 Missal, with a blessing attributed to Cardinal O'Malley.</p>
<p>The debts are stated plainly. No source gives a total count of 1962 Missal sites in Boston, so both site counts are null rather than guessed from named parishes; the Cathedral of the Holy Cross extraordinary-form listing in a 2021 bulletin was not re-verified for 2026 and is not counted; and the USCCB appointment notice gives Uglietto's birth as September 23, 1951, while Wikipedia and Prabook give September 24; the dossier follows the USCCB appointment notice. On the evidence searched, Uglietto's posture is no_record at medium confidence.</p>
