The following are links to Latin Mass locations in communion with the Roman Catholic Church. Links to Latin Mass Locations served by priests and communities not in communion with the Roman Catholic Church (e.g., SSPX, sedevacantists, various independent Catholic groups) are deliberately excluded.
It is commonly claimed that Catholics may fulfill their Sunday obligation at valid Catholic Masses offered by suspended, schismatic or otherwise censured priests. In response to such claims by those who participate in SSPX settings, the January, 2003 statement from Monsignor Perl of the Ecclesia Dei Commission says: "In the strict sense you may fulfill your Sunday obligation by attending a Mass celebrated by a priest of the Society of St. Pius X."
He says further: "We have already told you [in earlier communications] that we cannot recommend your attendance at such a Mass and have explained the reason why." And what was this reason why?
A celebration of Holy Mass should be done in communion with the Church and with the Pope, and with the bishop of the place. The celebration of the Mass should be done by a priest who is in union with the Church. Attendance at Masses celebrated by other priests is permitted only where access to a Mass celebrated by a priest in union with the Church is impossible. Now, the priests of the FSSPX are not in union with the Church because of their adherence to the schism of Archbishop LeFebvre who provoked the schism by his ordination of some bishops contrary to the will of the Pope, who has called the act on 30 June 1988 as schismatic. (Response of Monsignor Perl in April 2002 and restated in September 2002)
In other words, regular participation in SSPX settings is not permitted. Occasional participation is permitted “only where access to a Mass celebrated by a priest in union with the Church is impossible.”
