The Union of Utrecht of the Old Catholic Churches (UU) is a federation of Old Catholic churches, nationally organised from 1870 schisms which rejected Roman Catholic doctrines of the First Vatican Council; its member churches are not in communion with the Roman Catholic Church. The 1889 Declaration of Utrecht is one of three founding documents together called the Convention of Utrecht. Many provinces of the Union of Utrecht of the Old Catholic Churches are members of the World Council of Churches; the UU is in full communion with the Evangelical Lutheran Church of Sweden, the Anglican Communion through the 1931 Bonn Agreement; and, with the Philippine Independent Church, the Spanish Reformed Episcopal Church, and the Lusitanian Catholic Apostolic Evangelical Church through a 1965 extension
