The Ambrosian Rite is a Latin Catholic liturgical Western Rite used in the area of Milan. The Traditional Ambrosian Rite is the form of this rite as it was used before the changes that followed the Second Vatican Council.
Nowadays the Traditional Ambrosian Rite is mainly used on Sundays and Holy Days of Obligation in the church of Santa Maria della Consolazione in Milan, using the Ambrosian Missal of 1954, as permitted by Cardinal Archbishop of Milan Carlo Maria Martini on 31 July 1985. Another celebration on Sundays and Holy Days of Obligation was authorized from 18 October 2008 onward in the town of Legnano.[1] The Traditional Ambrosian Rite Mass may be said according to the Motu Proprio "Summorum Pontificum".[2]
