Tertullian,
Ante-Nicene Fathers Vol. III, Ethical…
(1885)
“ If, on the one hand, it is irreverent to sit under the eye, and over against the eye, of him whom you most of all revere and venerate; how much more, on the other hand, is that deed most irreligious under the eye of the living God, while the angel of prayer is still standing by [3] unless we are upbraiding God that prayer has wearied us! ”
