Chapter 6: Concerning the Night Vigils throughout the year.
Let it be known that we have
52 weeks in a year during which we have a Vigil every Sunday.
Thus, after we have counted all Sunday Vigils throughout the year,
we have 52 of them. Also, we have Vigils for the Lord's feasts
for every month. So, if we add these together, the total number
of Vigils throughout the year is 68. Furthermore, there are other
Vigils prescribed. These are celebrated according to the names
written in the Typikon in their places and the wishes of the Superior
when he sees that his churchmen diligently care about the salvation
of their souls. There is also another Vigil to add to these, that
is the Vigil for the Patron Saint of the church or monastery,
and this one should be celebrated and never be neglected.
