I quote articles 76 and 77:
Article 76
The Metropolitan is the point of reference of all bishops in his Archdiocese and they are under his authority.
Article 77
All bishops within the Antiochian See are auxiliary bishops and are directly under their spiritual authority.
I have the following comments:
1. In article 77 the antecedent of the pronoun "their" ("هم") (plural) is not immediately apparent, i.e. it is not clear to whom "their" refers. However, it is possible that "their" might refer to "the Metropolitan" ("المتروبوليت") (singular) in article 76.
2. If "their" does refer to "the Metropolitan," the Antiochian See clearly has a very different concept of auxiliary Bishops compared to the Catholic Churches.
3. All the Catholic Churches (both Latin and Eastern) distinguish between diocesan/eparchial Bishops and auxiliary Bishops. A diocesan Bishop (e.g. the Bishop of Van Nuys or the Bishop of Biloxi) is the Ordinary of his particular Church (diocese/eparchy), subject to the strictly limited authority of the Metropolitan (e.g. the Metropolitan Archbishop of Pittsburgh or the Metropolitan Archbishop of Mobile), who is himself the diocesan Bishop of the metropolitan See.
4. An auxiliary Bishop, on the other hand, is a Bishop who assists a diocesan Bishop in the government of his particular Church (diocese/eparchy).
5. What this decree effectively says is that only the Metropolitan Archbishop is a true diocesan/eparchial Bishop, and that only metropolitan Sees are true particular Churches. But that seems to be a very strange definition of a Metropolitan Archbishop and of a particular Church, as it leaves room for no other diocesan/eparchial Bishops at all, only auxiliary Bishops.
Thus, to sum up, it seems to me that the Greek Orthodox Patriarchate of Antioch has a very confused idea of both Arabic/English grammar and what constitutes a particular Church.
