Page "Traditionalist Catholic" Paragraph 5

Several officially-approved societies of traditionalist priests exist, most notably the Priestly Fraternity of St Peter ( FSSP ), the Institute of Christ the King Sovereign Priest ( ICRSS ), the Sons of the Most Holy Redeemer, the Institute of the Good Shepherd ( IGS ), the Servants of Jesus and Mary ( Servi Jesu et Mariae, SJM ), the Canons Regular of the New Jerusalem ( CRNJ ), the Canons Regular of Saint John Cantius ( SJC ), the Fraternity of Saint Vincent Ferrer, and the Personal Apostolic Administration of Saint John Mary Vianney ( PAASJV ).

There are also multiple monastic communities, including the Monastery of Our Lady of the Annunciation of Clear Creek, the Monastery of St. Benedict in Norcia, and the Monks of the Most Blessed Virgin Mary of Mount Carmel: see Communities using the Tridentine Mass.

These accept in principle the documents of the Second Vatican Council, and regard the changes associated with the Council ( such as the revision of the Mass liturgy ) as legitimate, but prefer the older forms and, with the approval of the Holy See, use those forms.
