IV. The Cult of the Blessed Virgin in the Church

66. Placed by the grace of God, as God's Mother, next to her Son, and exalted above all angels and men, Mary intervened in the mysteries of Christ and is justly honored by a special cult in the Church. Clearly from earliest times the Blessed Virgin is honored under the title of Mother of God, under whose protection the faithful took refuge in all their dangers and necessities.^21* Hence after the Synod of Ephesus the cult of the people of God toward Mary wonderfully increased in veneration and love, in invocation and imitation, according to her own prophetic words: "All generations shall call me blessed, because He that is mighty hath done great things to me".³⁰¹ This cult, as it always existed, although it is altogether singular, differs essentially from the cult of adoration which is offered to the Incarnate Word, as well to the Father and the Holy Spirit, and it is most favorable to it. The various forms of piety toward the Mother of God, which the Church within the limits of sound and orthodox doctrine, according to the conditions of time and place, and the nature and ingenuity of the faithful has approved, bring it about that while the Mother is honored, the Son, through whom all things have their being ³⁰² and in whom it has pleased the Father that all fullness should dwell,³⁰³ is rightly known, loved and glorified and that all His commands are observed.

67. 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.^22* But it exhorts theologians and preachers of the divine word to abstain zealously both from all gross exaggerations as well as from petty narrow-mindedness in considering the singular dignity of the Mother of God.^23* Following the study of Sacred Scripture, the Holy Fathers, the doctors and liturgy of the Church, and under the guidance of the Church's magisterium, let them rightly illustrate the duties and privileges of the Blessed Virgin which always look to Christ, the source of all truth, sanctity and piety. Let them assiduously keep away from whatever, either by word or deed, could lead separated brethren or any other into error regarding the true doctrine of the Church. Let the faithful remember moreover that true devotion consists neither in sterile or transitory affection, nor in a certain vain credulity, but proceeds from true faith, by which we are led to know the excellence of the Mother of God, and we are moved to a filial love toward our mother and to the imitation of her virtues.
