Edward J. Quigley, The Divine Office: A Study of the Roman Breviary
“ For who will be, asks the saint, unmoved by those frequent passages in the Psalms in which are proclaimed the immensity, the omnipotence, the infallible justice, the goodness, the clemency of God? Or who is not moved by the prayers and thanksgivings for benefits received by the humble and trustful petitions, by the cries of souls sorrowing for sin, found in the Psalms? Whom will the Psalmist not fill with admiration when he recounts the gifts of the Divine loving kindness towards the people of Israel and all mankind, and when he sets forth the truths of heavenly wisdom? ”
