The official news agency of the Priestly Fraternity of Saint Pius X (FSSPX / SSPX), DICI, published today an article on the reform of the Good Friday Prayer for the Jews, and adds this unsigned comment, the first on the matter in an official SSPX publication:
Following pressures foreign to the Catholic Church, the Pope considered himself forced to change the very venerable Prayer for the Jews which is a full part of the Good Friday liturgy. This prayer is one of the most ancient; it dates from around the 3rd century, and has thus been recited, throughout the history of the Church, as the full expression of the Catholic faith.
It must be mentioned that the comments by Cardinal Kasper - which we may consider as authorized - give this amputation the aspect of a true transformation, expressing a new theology of the relations with the Jewish people. It is part of the liturgical upheaval which is the characteristic mark of the Council and of the reforms it entailed.
Even though the need to accept the Messiah in order to be saved has been preserved, one cannot but deeply regret this change.
