On November 12, 2005 the Anglican Province of America, the Reformed Episcopal Church, and the Church of Nigeria (Anglican Communion) entered into a Covenant Union with one another. Signing this Covenant were the Most Rev'd Walter H. Grundorf, Presiding Bishop of the APA, the Most Rev'd Leonard W. Riches, Presiding Bishop of the REC, and the Most Rev'd Peter J. Akinola, Primate of All Nigeria. This historic agreement follows discussions that began among the three churches in 2004 and looks forward to a future wherein which we may all be one. Here is the text of the November 16, 2005 press release from Archbishop Akinola.

PRESS RELEASE
RE Covenant Between The Church of Nigeria (Anglican Communion) and the Reformed Episcopal Church and the Anglican Province of America.
In an historic moment, as part of the realignment of global Anglicanism, on November 12, 2005 in Pittsburgh, Pennsylvania, the Most Rev. Peter J. Akinola, Primate of the Church of Nigeria (Anglican Communion), the Most Rev. Leonard W. Riches, Presiding Bishop of the Reformed Episcopal Church, and the Most Rev. Walter H. Grundorf, Presiding Bishop of the Anglican Province of America, entered on behalf of their three Churches a Covenant Union of Anglican Churches in Concordat.
The purpose of the covenant of concord is to work together in the common cause of the Gospel of Jesus Christ, pledging to each other their mutual cooperation, support, discipline and accountability. Recognizing that all three Churches share a common heritage of faith and order within the Anglican tradition, they are united by saving belief in Jesus Christ as the Way, the Truth and the Life, and by their commitment to the Faith once delivered, based on the irrevocable Holy Scriptures of the Old and New Testaments as the final authority for faith and life.
It was agreed that ministers of these Churches, subject to the respective regulations within the jurisdictions, may be eligible to exercise pastoral ministry in each Church. Archbishops and bishops of the Churches in concordat may also be invited to conduct episcopal duties within the other jurisdictions with the blessing of the appropriate provincial authorities.
The three Churches have united specifically for joint mission in North America. Archbishops Riches and Grundorf welcomed the Church of Nigeria's CANA initiative. They assured Archbishop Akinola that, wherever possible, individual congregations of all three jurisdictions, within proximate geographic locations, would work closely and cooperatively together to demonstrate their commitment to one another and their desire to witness to a consistent Biblical, Evangelical and Catholic expression of faith in the Lord Jesus Christ.
