The United Church of England and Ireland

[gw1]

The Act of Union, 1800, uniting Great Britain and Ireland stated

"that it be the fifth Article of Union, that the Churches of England and Ireland, as now by law established, be united into one Protestant Episcopal Church, to be called, The United Church of England and Ireland; and that the doctrine, worship, discipline and government of the said United Church shall be, and shall remain in full force for ever, as the same are now by law established for the Church of England; and that the continuance and preservation of the said united Church, as the Establish-ed Church of England and Ireland, shall be deemed and taken to be an essential and fundamental part of the Union; and that in like manner the doctrine, worship, discipline and government of the Church of Scotland shall remain and be preserved as the same are now established by law, and by the Acts for the Union of the two kingdoms of England and Scotland".

Did this happen/not happen?  Where is the United Church of England and Ireland now? How has it since changed as it was to "remain in force for ever"?
