Use of both these texts, which included Pius V's revised calendar, was made obligatory throughout the
Latin Church except where other texts of at least two centuries' antiquity were in use, and departures from it were not allowed. The
Apostolic ConstitutionQuod a nobis, which imposed use of the Tridentine Roman Breviary, and the corresponding Apostolic Constitution Quo primum concerning the Tridentine Roman Missal both decreed: "No one whosoever is permitted to alter this letter or heedlessly to venture to go contrary to this notice of Our permission, statute, ordinance, command, precept, grant, indult, declaration, will, decree and prohibition. Should anyone, however, presume to commit such an act, he should know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul."[3]

1 November:
Feast of all Saints, Double, and (in the calendar given in the 1568 Roman Breviary[page needed] but not in the 1570 Roman Missal)[4] commemoration of
