Roman Catholic Archdiocese of Mercedes-Luján


The Archdiocese of Mercedes-Luján is a Roman Catholic archdiocese serving north-central Buenos Aires Province, Argentina. It was immediately subject to the Holy See, coming into 2019. Erected as the Diocese of Mercedes on 20 April 1934, it was renamed as the Diocese of Mercedes-Luján on 10 May 1989 and elevated on 21 November 1997. Its mother church is the Catedral Basílica de Mercedes-Luján in Mercedes.
On Friday, March 4, 2019, Pope Francis raised it to a metropolitan archdiocese, with three suffragan dioceses- two had been part of the La Plata Province and one had been part of the Buenos Aires Province. He accepted the resignation of Archbishop Agustin Roberto Radrizzani, S.D.B., who had been in office since 2007, and appointed as the first metropolitan archbishop the then-auxiliary bishop of the archdiocese, Jorge Eduardo Scheinig, who had been titular bishop of Ita, having been consecrated a bishop in 2017.
The suffragan dioceses are Merlo-Moreno, Nueve de Julio, and Zárate-Campana. The first had been in the Buenos Aires province, and the other two were in the La Plata province.
