Tierce.--The third hour or 9 A. M. One of the SEVEN CANONICAL HOURS
(which see).
Tradition.--A term used in the Thirty-fourth Article of Religion to
denote customs, rites, forms and ceremonies of the Church which have
been transmitted by oral communications or long established usage,
and which though not commanded in so many words in Holy Scripture,
yet have always been used and kept in the Holy Catholic Church. For
this reason they are revered, practiced and retained in its various
branches at the present time. Such traditions are the following:
1. The observance of the first day of the week instead of the
seventh.
2. The observance of the Christian Year, or the system of Feasts
and Fasts and Holy Seasons according to the events in our Lord's
Life.
