Reverence in Prayer
Whenever we want to ask some favor of a powerful man, we do it humbly and respectfully, for fear of presumption. How much more important, then, to lay our petitions before the Lord God of all things with the utmost humility and sincere devotion. We must know that God regards our purity of heart and tears of compunction, not our many words. Prayer should therefore be short and pure, unless perhaps it is prolonged under the inspiration of divine grace. In community, however, prayer should always be brief; and when the superior gives the signal, all should rise together.
(Rule of Saint Benedict, chap. 20)
