Mary commands all the heavenly choirs
“Actually every member of each of the nine choirs of Angels, not merely those called Angels and Archangels, has a guardianship of some kind, some over individual souls, others over cities, provinces, countries. Moreover, the very infidels, the atheists, the haters of God, each has his Angel Guardian, so that the invoking of that Angel by us when dealing with those cases should not be neglected.“
