Another historical reason for the Old Catholic Church in the United Kingdom declaring independence from the Union of Utrecht in 1910, was the continued acknowledgement of the Old Catholic Church in the United Kingdom that the Pope, the Bishop of Rome, remains the Patriarch of the West, and is considered, and honoured as, Primus inter Pares; as such he always continued (and continues) to be remembered, and prayed for, within the Canon of the Mass.
Regarding the doctrines and dogmas of Infallibility, the Old Catholic Church in the United Kingdom holds that inerrancy of dogma and doctrine rests with:

1.    Sacred Scripture (actual historical texts, and/or faithful and accurate translations)

2.    Sacred Tradition (in the spirit of the teachings of St. John Chrysostom’s wisdom: ‘Is it Tradition? Ask no more’)

3.    The declarations/dogmas of a validly held General Ecumenical Council of the whole Catholic Church

4.    To a substantial degree, with the ancient Augustine doctrine of Lex Orandi Lex Credendi with regard to the most Ancient of Sacred Liturgies which form part of the afore mentioned Sacred Tradition.

5.    The Patriarchs of the West (Rome) and East (Constantinople): should they declare Ex Cathedra upon faith and morals, speaking as the mouthpiece and arbiter of the whole Catholic Church, having consulted fully with the Bishops of the whole Church, and when what is declared upon is already firmly established (explicitly or implicitly) within Sacred Scripture and/or Sacred Tradition, and does not contradict, or is confirmed (either explicitly or implicitly) by, Sacred Scripture and Sacred Tradition.

The Filioque position: The Old Catholic Church in the United Kingdom maintains, as does the whole Eastern Orthodox Catholic Church, the solid and unquestioning beliefs as set out in the Creed of Nicaea/Constantinople of 381. We maintain that, whilst theological debate may continue regarding the Filioque clause, no Church and no Bishop or Bishops, nor successive Synods or Councils may change, alter, add to, or take away from, a Creed once it is proclaimed by a legitimate General Ecumenical Council, and that such Sacred Tradition is held as absolute by OCCUK.
