Religion in Austria
Catholicism is the largest religion in Austria, representing 57.9% of the total population in 2017. The Catholic Church's governing body in Austria is the Austrian Conference of Catholic Bishops, made up of the hierarchy of the two archbishops (Wien, Salzburg), the bishops and the abbot of territorial abbey of Wettingen-Mehrerau. Nevertheless, each bishop is independent in his own diocese, answerable only to the Pope. The current president of the Conference of Catholic Bishops is Cardinal Christoph Schönborn. Schönborn belongs to the Central European noble family of Schönborn. Although Austria has no primate, the archbishop of Salzburg is titled "Primus Germaniae" (Primate of Germany).
Religion in Switzerland
Christianity is the predominant religion of Switzerland, its presence going back to the Roman era. Since the 16th century, Switzerland has been traditionally divided into Roman Catholic and Reformed confessions. 
However, adherence to Christian churches has declined considerably since the late 20th century, from close to 94% in 1980 to about 66% as of 2017. Furthermore notable is the significant difference in church adherence between Swiss citizens (71%) and foreign nationals (50%) in 2017.
