We must conclude that, being necessary to God by a necessity which is called "hypothetical", (that is, because God so willed it), the Blessed Virgin is all the more necessary for men to attain their final end. Consequently we must not place devotion to her on the same level as devotion to the other saints as if it were merely something optional.
