Here’s an excerpt:
“…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.Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith.”
There is a beautiful story about Pope St. John XXIII, who was once recalling his earliest childhood memory. He tells of being a four-year old boy, and of how his family had gone to Mass for the one of the feasts of the Blessed Virgin. When they arrived, the church was overflowing with people, and being just a little boy, he was not able to see the ceremonies or venerate the image of the Blessed Mother.
Seventy-seven years later when he was reminiscing, Pope St. John XXIII recalled it in this way: “My only chance of seeing the image of the Madonna was through one of the two windows of the main entrance, which were very high and covered with an iron grating. Then my mother raised me up in her arms and said, “Look, Angelo, look how lovely the Madonna is – I consecrate you entirely to her!”
The Assumption of the Blessed Mother is something like that: Mary our Mother lifts us up. She lifts us up, and she lifts our cares and our concerns, all up to her Divine Son. She lifts us up in her Immaculate Heart so that we can catch a glimpse of the glory that will be ours in heaven.
Almighty and everlasting God, who didst assume the Immaculate Virgin Mary, Mother of thy Son, body and soul to the glory of heaven: grant us, we beseech thee; that being ever intent on things above, we may be worthy to be partakers of her glory hereafter; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
