Almost 62 years ago, on the first of November 1950, Pope Pius XII published Munificentissimus Deus, the Apostolic Constitution by which he declared what we celebrate today to be a dogma. It became a binding teaching, something that we are required to hold as Catholics. It goes so far that if we don’t agree with it, we can’t properly call ourselves Catholics. It’s like claiming that Jesus Christ was not the Son of God and still calling oneself Catholic. One of the identifying markers of one’s ‘Catholicity’ is missing, so whatever the person in question is, he is not Catholic [MD 45, 47].
This may all sound negative, focussing on what we must and what the consequences are if we don’t, but in essence a dogma is a positive. A reading of Munificentissimus Deus shows that the dogma we mark today, the Assumption of the Blessed Virgin Mary, grew organically from the heartfelt desires of many faithful and from the earlier dogmatic teaching of her Immaculate Conception, as defined by Blessed Pope Pius IX in 1854 [MD 6-9]. This dogma is then not something imposed from above, but a confirmation of what many had long held to be true. It is also a confirmation that the Assumption of Mary has always been “contained in the deposit of Christian faith entrusted to the Church” [MD 8].
The Venerable Pope Pius XII offers an extensive list of historical examples of this faith, even conviction, that the Blessed Virgin was assumed into heaven [MD 14-38], and then presents the official declaration of the dogma as such:
For which reason, after we have poured forth prayers of supplication again and again to God, and have invoked the light of the Spirit of Truth, for the glory of Almighty God who has lavished his special affection upon the Virgin Mary, for the honor of her Son, the immortal King of the Ages and the Victor over sin and death, for the increase of the glory of that same august Mother, and for the joy and exultation of the entire Church; by the authority of our Lord Jesus Christ, of the Blessed Apostles Peter and Paul, and by our own authority, we pronounce, declare, and define it to be a divinely revealed dogma: that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory. [MD 44]
Once more, the positive nature of this dogma, and others as well, is outlined a bit earlier in the Apostolic Constitution:
We, who have placed our pontificate under the special patronage of the most holy Virgin, to whom we have had recourse so often in times of grave trouble, we who have consecrated the entire human race to her Immaculate Heart in public ceremonies, and who have time and time again experienced her powerful protection, are confident that this solemn proclamation and definition of the Assumption will contribute in no small way to the advantage of human society, since it redounds to the glory of the Most Blessed Trinity, to which the Blessed Mother of God is bound by such singular bonds. It is to be hoped that all the faithful will be stirred up to a stronger piety toward their heavenly Mother, and that the souls of all those who glory in the Christian name may be moved by the desire of sharing in the unity of Jesus Christ’s Mystical Body and of increasing their love for her who shows her motherly heart to all the members of this august body. And so we may hope that those who meditate upon the glorious example Mary offers us may be more and more convinced of the value of a human life entirely devoted to carrying out the heavenly Father’s will and to bringing good to others. Thus, while the illusory teachings of materialism and the corruption of morals that follows from these teachings threaten to extinguish the light of virtue and to ruin the lives of men by exciting discord among them, in this magnificent way all may see clearly to what a lofty goal our bodies and souls are destined. Finally it is our hope that belief in Mary’s bodily Assumption into heaven will make our belief in our own resurrection stronger and render it more effective. [MD 42].
And in the meantime, a happy feast of the Assumption of the Blessed Virgin to all!
