Because of the universality of the Church with its "rich tradition and creativity" the Liturgy "is not to be distorted by communities or experts", the Pope said this in his general audience at St. Peter's Square.

It's not the individual priest or believer who celebrates the Liturgy, but it is God, who is the center of the Church, he stressed.
For that reason these forms must be true to the universal Church. The religious service is about the living presence of Jesus Christ and not for the recollection of something past, said Benedict XVI further.
If the celebration doesn't proceed with Christ as the center, then it doesn't concern Christian Liturgy. The Liturgy of the smallest community also has the entire Church present, the Pope stressed.
An example for alterations in the Liturgy can be found in a video presentation at a Carnival "Mass" in Ochsenhausen.
