While
canonization involves the addition of the saint's name to the Roman Martyrology, it does not necessarily involve the insertion of the saint's name also into the General Roman Calendar, which mentions only a very limited selection of canonized saints. Compared to
the previous edition of the calendar, around 200 saints were removed in the 1969 calendar, including
Valentine and
Christopher. Christopher is recognized as a saint of the Catholic Church, being listed as a martyr in the
Roman Martyrology under 25 July. In 1969,
Paul VI issued the
motu proprio Mysterii Paschalis. In it, he recognized that, while the written
Acts of Saint Christopher are merely legendary, attestations to the veneration of the martyr date from ancient times. His change in the calendar of saints included "leaving the memorial of Saint Christopher to local calendars" because of the relatively late date of its insertion into the Roman calendar. == Liturgical year ==
