Braga [once celebrated in Portugal] or the independent "old" Rites of the various religious orders, as they were celebrated up until the Liturgical reform.
The Ambrosian Rite, which dates from St. Ambrose (339-397), Bishop of Milan and some neighboring areas, as also in parts of the Diocese of Lugano in the Swiss Canton of Tessin. The Archbishop of Milan is numerically the largest Diocese in the world. Only some parishes of the Diocese celebrate in the Roman Rite.
The reigning Archbishop, Cardinal Dionigi Tettamanzi, has refused up until now the implementation of the Motu Propio Summorum Pontificum with the reason that the Ambrosian Rite isn't effected by it.
The same position has been used by the Bishops of other Rites in the Latin Church,, like the Archdiocese of Braga in Portugal.
Because of this various internet blogs of Tradition have expressed the "concern" that the rules of implementation for the Motu Proprio will not bring the hoped for spread of the use of the extraordinary form of the Roman Rite. Much worse, it will bring feared "limitations" . For this reason the call "Request for the Holy Father, Pope Benedict XVI, [English] in the event of the Instruction/Clarification of the Motu Proprio Summorum Pontificum" has been called to life. The text is in seven languages (English, German, French, Italian, Spanish, Portuguese und Dutch) and published on the internet for signatures.
