We believe that the divine presence is everywhere
and that "the eyes of the Lord
are looking on the good and the evil in every place" (Prov. 15:3).
But we should believe this especially without any doubt
when we are assisting at the Work of God.
To that end let us be mindful always of the Prophet's words,
" Serve the Lord in fear" (Ps. 2:11)
and again "Sing praises wisely" (Ps. 46:8)
and "In the sight of the Angels I will sing praise to You" (Ps. 137:1).
Let us therefore consider how we ought to conduct ourselves
in sight of the Godhead and of His Angels,
and let us take part in the psalmody in such a way
that our mind may be in harmony with our voice. RB 19

Let nothing, therefore, be put before the Work of God. RB 43
