Old Catholic Church

The term Old Catholic refers to several groups of Western Christians. These groups believe they maintain complete loyalty to the doctrines of the undivided church. They separated from the See of Rome following the First Vatican Council of 1869–70. This council introduced the dogma of papal infallibility. This is the belief that the Pope cannot err in matters of faith and morals. Many followers of the Old Catholic movement rejected this specific teaching. They sought to preserve what they viewed as older, more traditional practices. Today, the movement remains a distinct part of the global Christian landscape.

The mechanism of the movement involves a break in administrative and theological authority. After the First Vatican Council, many Catholics in Germany, Austria-Hungary, and Switzerland disagreed with the new papal definitions. These individuals sought new leadership to continue their religious life. They often turned to the See of Utrecht for support. The Archbishop of Utrecht would ordain new priests and bishops for these groups. This connection allowed them to form organized religious bodies. This process helped them transition from isolated dissenters to established church unions.

There are several distinct types of Old Catholic groups. The most prominent is the Union of Utrecht (UU). This union includes member churches in Germany, Switzerland, the Netherlands, Austria, Poland, and the Czech Republic. Another major group is the Union of Scranton (US). There are also Independent Old Catholics. These individuals belong to the independent sacramental movement. They do not consider recognition by the Union of Utrecht as a requirement for their identity. These groups are separate from Traditionalist Catholicism and are not in full communion with the Holy See.

The history of these groups traces back to the 18th century. In the Netherlands, members of the See of Utrecht refused to obey papal authority. This began after the removal of Petrus Codde in 1702. The Diocese of Utrecht then asserted the right to elect its own archbishop in 1724. This led to the consecration of Cornelius Steenoven without a papal mandate. This event created a de facto independent church in the Netherlands. Later, in the 1870s, the movement expanded significantly across Europe. Leaders like the church historian Ignaz von Döllinger helped organize the German, Austrian, and Swiss groups.

Significant changes occurred within the liturgy and social rules of these churches. In the middle of the 18th century, the Dutch Old Catholics began using the vernacular. The vernacular refers to the local language of the people rather than Latin. By 1877, the use of Latin in liturgy was completely replaced by local languages. In 1874, the Old Catholics also removed the requirement of clerical celibacy. These shifts helped the movement adapt to the cultures of its members. Such changes helped distinguish them from the Roman Catholic Church.

Specific numbers help illustrate the scale and shifts within the movement. According to the 2020 World Christian Database, there are 4,896,000 Old Catholics worldwide. In the 1600s, Jesuits made up between 10 and 15 percent of the Dutch clergy. By 1629, there were 321 Catholic priests in the United Provinces. Of these, 34 were Jesuits. A major split occurred in 2008 when the Polish National Catholic Church created the Union of Scranton. This separation happened because the Polish group disagreed with the Union of Utrecht. They protested decisions regarding the ordination of women and the blessing of same-sex marriages.

The Old Catholic movement connects to many broader religious and political systems. The Union of Utrecht maintains full communion with the Anglican Communion. It is also in communion with the Evangelical Lutheran Church of Sweden and the Philippine Independent Church. Many Union of Utrecht churches are members of the World Council of Churches. Historically, the movement interacted with political shifts, such as the Kulturkampf in Germany. This was a period of conflict between the government of Otto von Bismarck and the Catholic Church. These connections show how religious identity often intersects with national and international structures.
