We have a Press Release from the Vatican but not a document. I suppose it's a start.
COMMUNIQUE CONCERNING ARCHBISHOP EMMANUEL MILINGO
VATICAN CITY, SEP 26, 2006 (VIS) - The Holy See Press Office today released a communique concerning the present ecclesial position of Archbishop Emmanuel Milingo. The text of the communique is given below:
"With great concern, the Holy See has followed the recent activities of Archbishop Emmanuel Milingo, emeritus of Lusaka, Zambia, with his new association of married priests, spreading division and confusion among the faithful.
"Church representatives of various levels have tried in vain to contact Archbishop Milingo in order to dissuade him from persisting in actions that provoke scandal, especially among the faithful who followed his pastoral ministry in favor of the poor and the sick.
"Bearing in mind the understanding shown, also recently, by Peter's Successor towards this aged pastor of the Church, the Holy See has awaited with vigilant patience the evolution of events which, unfortunately, have led Archbishop Milingo to a position of irregularity and of progressively open rupture of communion with the Church, first with his attempted marriage and then with the ordination of four bishops on Sunday, September 24, in Washington D.C., U.S.A.
"For this public act both Archbishop Milingo and the four ordinands have incurred excommunication 'latae sententiae,' as laid down in Canon 1382 of the Code of Canon Law. Moreover, the Church does not recognize, nor does she intend to recognize in the future, these ordinations and all ordinations deriving from them; and she considers the canonical status of the four supposed-bishops as being that they held prior to this ordination.
The Apostolic See, attentive to the unity and peace of the flock of Christ, had hoped that the fraternal influence of people close to Archbishop Milingo would cause him to rethink and return to full communion with the Pope. Unfortunately the latest developments have made these hopes more unlikely.
"At times of ecclesial suffering such as these, may prayers intensify among all the community of the faithful."
