6.3. Can I attend a Mass that uses the Novus Ordo or mentions the Vatican II popes?
No. You must avoid all Masses that are:
Novus Ordo (New Mass),
Offered by invalidly ordained priests,
Or include the name of a false (Vatican II) pope (“una cum” Masses).
These are not simply flawed — they are dangerous to faith and are invalid, leading to sacrilege or loss of grace. Attendance at such Masses is an objective compromise with a false religion.
