Many provinces of the Union of Utrecht of the Old Catholic Churches are members of the World Council of Churches.

History
Foundation and enlargement
The mother church, the Old Catholic Church of the Netherlands, was established in the 18th century as a result of tensions between the local Catholic hierarchy and the Roman Curia. The other churches, such as the Catholic Diocese of the Old Catholics in Germany, and the Christian Catholic Church of Switzerland, followed suit after the First Vatican Council, which defined the dogma of papal infallibility.Missionary activity and schisms
In the former Yugoslavia, the union had three organized Old Catholic episcopal jurisdictions: Old Catholic Church of Croatia, Old Catholic Church of Slovenia, and Old Catholic Church of Serbia. Three churches formed "Union of Old-Catholic Churches in Yugoslavia". This union eventually ceased to exist with break-up of Yugoslavia and even before that, the Old Catholic bishopric in Serbia was extinguished, and the same happened with bishoprics in Slovenia and Croatia. Finally, remaining Old Catholic parishes in Croatia and other parts of former Yugoslavia were placed under jurisdiction of the Old Catholic Church of Austria.In 1997, the International Old Catholic Bishops' Conference retracted its 1976 declaration opposing the admission of women into the clergy, allowing the churches to do so and, knowing this would lead to a break in communionship across the member churches, established a 6 year period to restore full communion. In turn, in 1998 the Polish National Catholic Church's General Synod put in place a set of guidelines heavily restricting intercommunion with Old Catholic Churches that ordained women including forbidding its bishops from being part of consecrations of any bishops from such churches, and vice versa. The conference stated in 2003 that full communion "could not be restored and that therefore, as a consequence, the separation of our Churches follows.", which effectively expelled the Polish National Catholic Church.
The Old Catholic Church of Austria approved the blessing of same-sex unions in 1998 without deliberation; in contrast, the Polish National Catholic Church disapproved the blessing of same-sex unions in 2002 and "described homosexual practice as sinful". The Polish National Catholic Church established the Union of Scranton in 2008, and no other North American body has been recognized by the International Old Catholic Bishops' Conference.
The Old Catholic Church of Slovakia was a member church of the Union of Utrecht from 2000 but it was removed from membership in 2004.
In July 2011, the Christian Catholic Church of Switzerland ended its mission to Old Catholic parishes in Italy. "In cooperation with ecumenical partner churches" the parishes were "offered a model that guarantees their continued pastoral care".
