Roman Catholic Archdiocese of Moncton
The Roman Catholic Archdiocese of Moncton (French: Archidiocèse de Moncton) is a Latin Church ecclesiastical jurisdiction serving the Acadian Catholic community in New Brunswick, Canada. Established on 22 February 1936 through papal decree, it became the central archdiocese for New Brunswick’s Catholic province[1][4].

History

The archdiocese was created following petitions by Bishops Édouard LeBlanc (Saint John) and Patrice Chiasson (Chatham), who argued that a Moncton-based archdiocese would strengthen Catholic influence in education and governance[1]. The Vatican formalized its establishment during a restructuring prompted by the deaths of Bishop LeBlanc (1935) and Halifax’s Bishop O’Donnell (1936)[1]. On 30 August 1936, Bishop Patrice Bray proclaimed the archdiocese’s creation, with Louis-Joseph-Arthur Melanson appointed as its first archbishop[1][5].

Melanson, of Acadian descent, was ordained in 1905 and previously served as Bishop of Gravelbourg, Saskatchewan[5]. His tenure (1936–1941) marked the archdiocese’s foundational years, followed by successors including Norbert Robichaud (1942–1972) and Donat Chiasson (1972–1995)[2]. By 1986, the archdiocese encompassed 50 parishes[3].

Structure and Activities

The archdiocese operates under the Rite Latin and forms part of the ecclesiastical province of New Brunswick[4]. Its governance model emphasizes pastoral care, education, and community outreach, reflecting its historical role in advocating for Acadian Catholic rights and French-language education[1][3]. The coat of arms, designed in 1937 by Brother Gérard Brassard, features M.A. (Moncton Archdiocese) in Gothic script, a six-pointed star, a crescent moon, and a ship symbolizing Acadian heritage[3].

Registered as a nonprofit organization (BN: 130091135RR0001), it coordinates parish activities, including liturgical services and charitable initiatives, through entities such as the listed website domain.
