Professor Bruce Mullin provided an affidavit and expert testimony for the court in Fort Worth on behalf of The Episcopal Church. It is a very well constructed statement of Episcopal Church polity. You can read the document HERE.
For those who wondered where the rejoinder to the Anglican Communion Institute papers on hierarchy in The Episcopal Chruch might come from, here it is.
Dr. Mullin is Professor of Modern Anglican Studies and The Society for the Promotion of Religion and Learning Professor of History and World Missions. His paper is being or has been vetted by learned colleagues in Theology and Church History.
Those interested will want to read the whole thing. Those with less interest in the details will want the conclusion: He was asked to offer expert testimony on
"The current and historical hierarchical organization and structure of TheEpiscopal Church and the consequent reasons why dioceses and parishes of the Church, as opposed to their individual leaders, may not, consistent with the Church's polity, articulated in its Constitution, canons, and Book of Common Prayer, unilaterally withdraw or disaffiliate from the Church and its governing body, the General Convention, or, in the case of parishes, from their dioceses."
The last two pages of the document give the conclusion summary in support of this position.
Read the whole thing, or at least take a look at the last two pages.
ACI does not seem to have felt the need to respond to this. Perhaps they have and I haven't seen it. I am sure I will be corrected if that is so.
