46 From the ancient Christian documents, from prayers of the liturgy, from the innate piety of the Christian people, from works of art, from every side We have gathered witnesses to the regal dignity of the Virgin Mother of God; We have likewise shown that the arguments deduced by Sacred Theology from the treasure store of the faith fully confirm this truth. Such a wealth of witnesses makes up a resounding chorus which changes the sublimity of the royal dignity of the Mother of God and of men, to whom every creature is subject, who is "exalted to the heavenly throne, above the choirs of angels."
