True Devotion to Mary, St. Louis De Montfort, 1941, Preliminary Remarks, pg. 5:
". . . the word divine may be used without attributing the nature of divinity to the person or thing thus qualified. We speak of our own prayers, whether addressed to God or to His Saints, as a divine service. The Psalmist speaks of us all as being gods and sons of the Most High; and yet no one takes offense, because the sense given to the words uttered is understood. Mary may be called divine because divinely chosen for the divine office of Mother" of a divine Person, Jesus Christ ( Cardinal Vaughan, preface to the English edition of True Devotion).
