FOR IMMEDIATE RELEASE: June 23, 2023

The Most Reverend Robert Brennan, Bishop of Brooklyn, today announced the appointment of four Regional Episcopal Vicars and the restructuring of the 22 parish deaneries throughout Brooklyn and Queens. The new structure highlights Bishop Brennan’s commitment to enhancing the role of the deaneries and collaboration among parishes.

Reverend John J. Costello (Queens East), Reverend Joseph M. Hoffman (Brooklyn East), Most Reverend Witold Mroziewski (Brooklyn West), and Very Reverend Peter J. Purpura (Queens West) have each been selected as Regional Episcopal Vicars. We anticipate the celebration of a Mass of Installation at the Co-Cathedral of Saint Joseph in the fall.

“In an effort to increase the involvement of the Vicars at the parish and deanery level, I have decided to expand the number of such positions from two to four in the Diocese. I am asking a lot of these priests taking on this new role, all while remaining parish pastors, and so expanding the number of regional vicariates will make the responsibilities more manageable,” said Bishop Robert Brennan.

“We have been working hard during the last year to reinvigorate the deaneries, and I am very satisfied with the progress made towards a more proactive working relationship among parishes. As we move forward, aware of the changing demographics and with the reality of fewer priests, we must look in this direction as we plan for the continued vitality of the Church here in Brooklyn and Queens in the future,” continued Bishop Brennan.

The Regional Vicars will have a general delegation, permission to grant confessional faculties, and permission to dispense from matrimonial impediments within the confines of the Diocese of Brooklyn. The Regional Vicars will meet with Bishop Brennan regularly to report on and discuss matters within their vicariate. They will serve as an ex-officio member of the Presbyteral Council, will serve on the Diocesan Assignment Board, and represent Bishop Brennan at civic and religious functions as requested.

The Regional Vicars will attend deanery meetings and meet individually with the deans in their vicariate a minimum of four times per year. They will provide input and encouragement on Diocesan initiatives, install and assist new pastors in their region, provide investigation and reconciliation to concerns made to the Bishop, assume a key role in Diocesan Pastoral Planning, address parish communities when allegations are made related to the Dallas Charter and/or Adult allegations, and in situations involving priests or deacons, collaborate with the Vicar of Clergy and Consecrated Life to address the situation and determine a proper remedy.

“The bishop has established these four vicariates in order to facilitate and enhance future pastoral initiatives in the Diocese. These well-respected members of the presbyterate bring with them extensive service as parish leaders. Their efforts will help advance conversations and plans to best serve the Catholic community within their region of the Diocese,” said Monsignor Joseph Grimaldi, Vicar General of the Diocese of Brooklyn.

The current Territorial Vicars are Most Reverend Neil Tiedemann (Brooklyn) and Most Reverend Witold Mroziewski (Queens). Bishop Tiedemann, who turned 75 years old earlier this year, has submitted his letter of resignation to Pope Francis as Canon Law requires, and his retirement is pending. Upon the Holy Father’s acceptance of Bishop Tiedemann’s resignation, these appointments will become effective.

Biographical information and photos of the new Regional Episcopal Vicars, and the composition and leadership of the new deaneries follow. The previous Diocesan deanery map divided Brooklyn and Queens by north and south. Parishes will now be categorized as east and west within each borough.
