Canon
XLIX.
Lent the Bread must not
be offered except on the Sabbath Day and on the Lord’s Day
only.
Notes.
In Lent the offering should be made only on the Sabbath
and on the Lord’s day.
This canon, which was repeated by the Trullan Synod in
its fifty-second canon, orders that on ordinary week days during Lent, only a Missa Præsanctificatorum should take place, as is still the custom with the Greeks on all days of penitence and mourning, when it appears to them unsuitable to have the full liturgy, and as Leo Allatius says, for this reason, that the consecration is a joyful act. A comparison of the above sixteenth canon, however, shows that Saturday was a special exception.
To the Saturdays and Sundays mentioned by Hefele must be
added the feast of the Annunciation, which is always solemnized with a
full celebration of the Liturgy, even when it falls upon Good
Friday.
