Catholic Wisdom
"For from her, as in a most abundant conduit, the drafts of heavenly graces are given: '... in her hands are the treasures of the mercies of the Lord; for God wills that she be the principle of all good things.'"
--Leo XIII, Encyclical letter Diuturni temporis spatium, Sept 5, 1898 (internal quote from St. John Damascene (Series I De Nativitate Virginis) and St. Irenaeus, Against Valentinus III. 33).
