Holy Rule Of Saint Benedict
Of Giving the Signal for the Time of the Work of God
Let it be the Abbot's care that the time for the Work of God be
announced both by day and by night; either to announce it himself, or
to entrust this charge to a careful brother that everything may be done
at the proper time.
Let those who have been ordered, intone the psalms or the antiphons in
their turn after the Abbot. No one, however, should presume to sing or
read unless he is able so to perform this office that the hearers may
be edified; and let it be done with humility, gravity, and reverence by
him whom the Abbot hath ordered.
