One tradition of the Church has this story about the death and Assumption of the Blessed Virgin Mary.
After the ascension of Our LORD Jesus Christ into Heaven, one of the things our Blessed Mother prayed to Her Son for was that all the Apostles should be around to bury Her when the time would come for Her to depart this world.
While still living with St. John at Ephesus, the Blessed Virgin Mary became ill at the age of 62. Meanwhile the Apostles were all engaged with their apostolic work in various parts of the world.
In answer to Her prayer, the Holy Spirit infused into the minds of them all a great urge to come home and see Mary whom they all regarded as their Mother. Ephesus was indeed a place all the Apostles regarded as their family home where they all returned to from time to time from their various stations. They all made it a point of duty to return home and visit their Mother and talk to Her about their work and how the gospel of Her Son Jesus Christ had been spreading all over the world.
While Mary lay ill in bed, the Apostles arrived one after the other to the surprise of all. Each one of them wondered if they other had recieved a message about Mother’s ill health before coming home.
They all talked about the burning desire to come home which suddenly came upon them.
The Apostles stood around Our Lady’s bed as she breathed Her last but before then, St. Peter anointed Her with oil and gave Her Holy Communion.
One of the Apostles of Jesus was not present at this time, guess who? St. Thomas. He came home late from India the following day accompanied by an Indian servant. He too spoke of the same urge to come home but was prevented from returning earlier by an appointment he had with an Indian Chief who had accepted Christ and had pleaded with him to come and baptize his household. He waited to meet with this appointment and thus was not present at the passing away of the Blessed Virgin Mary.
After She died, the Apostles carried the body of the Blessed Virgin Mary and laid Her in a tomb wrapping a cloth around Her in accordance with Jewish tradition.
When Thomas arrived and heard that Blessed Mother had died and been buried, he wept bitterly and requested to be taken to the tomb so as to see Her and pay his last respect. Peter requested John and a few other Apostles (who would help in removing the cover stone) to accompany Thomas to the tomb.
When the stoned was rolled away, to their utter amazement the body of the Holy Virgin was no longer there. All that was left was the cloth with which She was wrapped.
This piece of cloth mysteriously rapped around Our Lady’s garment in the same form and pattern She was wrapped showing no evidence of having been removed.
Obvious it is that no human can remove the body without touching the cloths wrapped around Her, the Apostles knew it was obvious Jesus had sent the angel to bring His beloved Mother’s body up to Him in Heaven not waiting until the day of resurrection to unite the body with the soul in Heaven.
Thomas and the other Apostles hurried back to Peter to report what they saw at the tomb and while they were discussing it, they recalled and incident that happened during the burial the day before.
They recalled that after they had laid Our Lady’s body in the tomb the previous day and we’re going back home, they had noticed rays of light shining over the tomb from above. They never did imagine the angels coming down with instructions from Heaven to bring Her body into glory until the experience of showing Thomas the tomb did reveal so.
Although the Assumption of the Blessed Virgin Mary’s body and soul was well known by the Apostles and early Christians, the Church’s doctrine on Assumption yet was not based on this event.
The Church based her teaching on revelations of the Holy Spirit as Jesus did assure the Spirit would Jn16:13 and in addition to Our Lady having revealed herself as the Lady of Assumption in one of Her apparitions go to confirm what the Holy Spirit revealed to the Church which Pope Pius XII formally proclaimed in 1950 as a dogma of the Catholic Church.
On November 1, 1950, in the Apostolic Constitution Munificentissimus Deus Pope Pius XII declared the Assumption of Mary as a dogma:
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.
