“This most Holy Synod deliberately teaches this Catholic doctrine and at the same time admonishes all the sons of the Church that the cult, especially the liturgical cult, of the Blessed Virgin, be generously fostered, and the practices and exercises of piety, recommended by the magisterium of the Church toward her in the course of centuries be made of great moment, and those decrees, which have been given in the early days regarding the cult of images of Christ, the Blessed Virgin and the saints, be religiously observed.”
-Lumen Gentium, 67
