The following is taken from the preamble of the Statutes of the Union of Scranton:
“The Union of Scranton is a union of Churches – and their bishops governing them – that is determined to maintain and pass on the Catholic faith, worship, and essential structure of the Undivided Church of the first millennium. The Union of Scranton finds its origins in the development of the Union of Utrecht established on September 24, 1889, in Utrecht, Holland (…) The full communion of the Churches found its expression and was evident in the bishops uniting to form a Bishops’ Conference, which other bishops later joined. Since the Polish National Catholic Church (PNCC) continues to hold the Declaration of Utrecht as a normative document of faith, the development of the Union of Scranton follows a similar design.
The Union of Scranton emerged because certain member Churches of the Union of Utrecht unilaterally began to ordain women to the Priesthood and to bless same-sex unions in opposition to Holy Scripture and the Sacred Tradition of the Undivided Church. Since November 20, 2003 the PNCC is neither in communion, nor affiliated with the Churches of the Union of Utrecht.”
