This is an ancient account attributed to St John the Beloved (who is also called “the Theologian” or “the Divine”) Granted it is not an official document, but is nice to read for personal knowledge and devotion:
The Account of St. John the Theologian of the Falling Asleep of the Holy Mother of God.
As the all-holy glorious mother of God and ever-virgin Mary, as was her wont, was going to the holy tomb of our Lord to burn incense, and bending her holy knees, she was importunate that Christ our God who had been born of her should return to her. And the Jews, seeing her lingering by the divine sepulchre, came to the chief priests, saying: Mary goes every day to the tomb. And the chief priests, having summoned the guards set by them not to allow anyone to pray at the holy sepulchre, inquired about her, whether in truth it were so.
And the guards answered and said that they had seen no such thing, God having not allowed them to see her when there. And on one of the days, it being the preparation, the holy Mary, as was her wont, came to the sepulchre; and while she was praying, it came to pass that the heavens were opened, and the archangel Gabriel came down to her and said: Hail, you that brought forth Christ our God! Your prayer having come through to the heavens to Him who was born of you, has been accepted; and from this time, according to your request, you having left the world, shall go to the heavenly places to your Son, into the true and everlasting life.
And having heard this from the holy archangel, she returned to holy Bethlehem, having along with her three virgins who ministered unto her. And after having rested a short time, she sat up and said to the virgins: Bring me a censer that I may pray. And they brought it, as they had been commanded. And she prayed, saying: My Lord Jesus Christ, who deigned through Your supreme goodness to be born of me, hear my voice, and send me Your apostle John, in order that, seeing him, I may partake of joy; and send me also the rest of Your apostles, both those who have already gone to You, and those in the world that now is, in whatever country they may be, through Your holy commandment, in order that, having beheld them, I may bless Your name much to be praised; for I am confident that You hear Your servant in everything.
And while she was praying, I John came, the Holy Spirit having snatched me up by a cloud from Ephesus, and set me in the place where the mother of my Lord was lying. And having gone in beside her, and glorified Him who had been born of her, I said: Hail, mother of my Lord, who brought forth Christ our God, rejoice that in great glory you are going out of this life. And the holy mother of God glorified God, because I John had come to her, remembering the voice of the Lord, saying: Behold your mother, and, behold your son. John 19:26-27 And the three virgins came and worshipped.
And the holy mother of God says to me: Pray, and cast incense. And I prayed thus: Lord Jesus Christ, who has done wonderful things, now also do wonderful things before her who brought You forth; and let Your mother depart from this life; and let those who crucified You, and who have not believed in You, be confounded. And after I had ended the prayer, holy Mary said to me: Bring me the censer. And having cast incense, she said, Glory to You, my God and my Lord, because there has been fulfilled in me whatsoever You promised to me before you ascended into the heavens, that when I should depart from this world You would come to me, and the multitude of Your angels, with glory. And I John say to her: Jesus Christ our Lord and our God is coming and you see Him, as He promised to you. And the holy mother of God answered and said to me: The Jews have sworn that after I have died they will burn my body.
And I answered and said to her: Your holy and precious body will by no means see corruption. And she answered and said to me: Bring a censer, and cast incense, and pray. And there came a voice out of the heavens saying the Amen. And I John heard this voice; and the Holy Spirit said to me: John, have you heard this voice that spoke in the heaven after the prayer was ended? And I answered and said: Yes, I heard. And the Holy Spirit said to me: This voice which you heard denotes that the appearance of your brethren the apostles is at hand, and of the holy powers that they are coming hither today.
And at this I John prayed.
And the Holy Spirit said to the apostles: Let all of you together, having come by the clouds from the ends of the world, be assembled to holy Bethlehem by a whirlwind, on account of the mother of our Lord Jesus Christ; Peterfrom Rome, Paul from Tiberia, Thomas from Hither India, James from Jerusalem. Andrew, Peter’s brother, and Philip, Luke, and Simon the Cananæan, and Thaddæus who had fallen asleep, were raised by the Holy Spirit out of their tombs; to whom the Holy Spirit said: Do not think that it is now the resurrection; but on this account you have risen out of your tombs, that you may go to give greeting to the honour and wonder-working of the mother of our Lord and Saviour Jesus Christ, because the day of her departure is at hand, of her going up into the heavens.
And Mark likewise coming round, was present from Alexandria; he also with the rest, as has been said before, from each country. And Peter being lifted up by a cloud, stood between heaven and earth, the Holy Spirit keeping him steady. And at the same time, the rest of the apostles also, having been snatched up in clouds, were found along with Peter. And thus by the Holy Spirit, as has been said, they all came together.
And having gone in beside the mother of our Lord and God, and having adored, we said: Fear not, nor grieve; God the Lord, who was born of you, will take you out of this world with glory. And rejoicing in God her Saviour, she sat up in the bed, and says to the apostles: Now have I believed that our Master and God is coming from heaven, and I shall behold Him, and thus depart from this life, as I have seen that you have come. And I wish you to tell me how you knew that I was departing and came to me, and from what countries and through what distance you have come hither, that you have thus made haste to visit me. For neither has He who was born of me, our Lord Jesus Christ, the God of the universe, concealed it; for I am persuaded even now that He is the Son of the Most High.
And Peter answered and said to the apostles: Let us each, according to what the Holy Spirit announced and commanded us, give full information to the mother of our Lord. And I John answered and said: Just as I was going in to the holy altar in Ephesus to perform divine service, the Holy Spirit says to me, The time of the departure of the mother of your Lord is at hand; go to Bethlehem to salute her. And a cloud of light snatched me up, and set me down in the door where you are lying. Peter also answered: And I, living in Rome, about dawn heard a voice through the Holy Spirit saying to me, The mother of your Lord is to depart, as the time is at hand; go to Bethlehem to salute her.
And, behold, a cloud of light snatched me up; and I beheld also the other apostles coming to me on clouds, and a voice saying to me, Go all to Bethlehem. And Paul also answered and said: And I, living in a city at no great distance from Rome, called the country of Tiberia, heard the Holy Spirit saying to me, The mother of your Lord, having left this world, is making her course to the celestial regions through her departure; but go also to Bethlehem to salute her. And, behold, a cloud of light having snatched me up, set me down in the same place as you. And Thomas also answered and said: And I, traversing the country of the Indians, when the preaching was prevailing by the grace of Christ, and the king’s sister’s son Labdanus by name, was about to be sealed by me in the palace, on a sudden the Holy Spirit says to me, Go also, Thomas, to Bethlehem to salute the mother of your Lord, because she is taking her departure to the heavens.
And a cloud of light having snatched me up, set me down beside you. And Mark also answered and said: And when I was finishing the canon of the third day in the city of Alexandria, just as I was praying, the Holy Spirit snatched me up, and brought me to you. And James also answered and said: While I was in Jerusalem, the Holy Spirit commanded me, saying, Go to Bethlehem, because the mother of your Lord is taking her departure. And, behold, a cloud of light having snatched me up, set me beside you.
And Matthew also answered and said: I have glorified and do glorify God, because when I was in a boat and overtaken by a storm, the sea raging with its waves, on a sudden a cloud of light overshadowing the stormy billow, changed it to a calm, and having snatched me up, set me down beside you. And those who had come before likewise answered, and gave an account of how they had come. And Bartholomew said: I was in the Thebais proclaiming the word, and behold the Holy Spirit says to me, The mother of your Lord is taking her departure; go, then, to salute her in Bethlehem. And, behold, a cloud of light having snatched me up, brought me to you.
The apostles said all these things to the holy mother of God, why they had come, and in what way; and she stretched her hands to heaven and prayed, saying: I adore, and praise, and glorify Your much to be praised name, O Lord, because You have looked upon the lowliness of Your handmaiden, and because You that are mighty has done great things for me; and, behold, all generations shall count me blessed. Luke 1:48 And after the prayer she said to the apostles: Cast incense, and pray.
And when they had prayed, there was thunder from heaven, and there came a fearful voice, as if of chariots; and, behold, a multitude of a host of angels and powers, and a voice, as if of the Son of man, was heard, and the seraphim in a circle round the house where the holy, spotless mother of God and virgin was lying, so that all who were in Bethlehem beheld all the wonderful things, and came to Jerusalem and reported all the wonderful things that had come to pass. And it came to pass, when the voice was heard, that the sun and the moon suddenly appeared about the house; and an assembly of the first-born saints stood beside the house where the mother of the Lord was lying, for her honour and glory.
And I beheld also that many signs came to pass, the blind seeing, the deaf hearing, the lame walking, lepers cleansed, and those possessed by unclean spirits cured; and everyone who was under disease and sickness, touching the outside of the wall of the house where she was lying, cried out: Holy Mary, who brought forth Christ our God, have mercy upon us. And they were straightway cured. And great multitudes out of every country living in Jerusalem for the sake of prayer, having heard of the signs that had come to pass in Bethlehem through the mother of the Lord, came to the place seeking the cure of various diseases, which also they obtained. And there was joy unspeakable on that day among the multitude of those who had been cured, as well as of those who looked on, glorifying Christ our God and His mother. And all Jerusalem from Bethlehem kept festival with psalms and spiritual songs.
And the priests of the Jews, along with their people, were astonished at the things which had come to pass; and being moved with the heaviest hatred, and again with frivolous reasoning, having made an assembly, they determine to send against the holy mother of God and the holy apostles who were there in Bethlehem. And accordingly the multitude of the Jews, having directed their course to Bethlehem, when at the distance of one mile it came to pass that they beheld a frightful vision, and their feet were held fast; and after this they returned to their fellow-countrymen, and reported all the frightful vision to the chief priests.
And they, still more boiling with rage, go to the procurator, crying out and saying: The nation of the Jews has been ruined by this woman; chase her from Bethlehem and the province of Jerusalem. And the procurator, astonished at the wonderful things, said to them: I will chase her neither from Bethlehem nor from any other place. And the Jews continued crying out, and adjuring him by the health of Tiberius Cæsar to bring the apostles out of Bethlehem. And if you do not do so, we shall report it to the Cæsar.
Accordingly, being compelled, he sends a tribune of the soldiers against the apostles to Bethlehem. And the Holy Spirit says to the apostles and the mother of the Lord: Behold, the procurator has sent a tribune against you, the Jews having made an uproar. Go forth therefore from Bethlehem, and fear not: for, behold, by a cloud I shall bring you to Jerusalem; for the power of the Father, and the Son, and the Holy Spirit is with you. The apostles therefore rose up immediately, and went forth from the house, carrying the bed of the Lady the mother of God, and directed their course to Jerusalem; and immediately, as the Holy Spirit had said, being lifted up by a cloud, they were found in Jerusalem in the house of the Lady. And they stood up, and for five days made an unceasing singing of praise.
And when the tribune came to Bethlehem, and found there neither the mother of the Lord nor the apostles, he laid hold of the Bethlehemites, saying to them: Did you not come telling the procurator and the priests all the signs and wonders that had come to pass, and how the apostles had come out of every country? Where are they, then? Come, go to the procurator at Jerusalem. For the tribune did not know of the departure of the apostles and the Lord’s mother to Jerusalem. The tribune then, having taken the Bethlehemites, went in to the procurator, saying that he had found no one. And after five days it was known to the procurator, and the priests, and all the city, that the Lord’s mother was in her own house in Jerusalem, along with the apostles, from the signs and wonders that came to pass there. And a multitude of men and women and virgins came together, and cried out: Holy virgin, that brought forth Christ our God, do not forget the generation of men.
And when these things came to pass, the people of the Jews, with the priests also, being the more moved with hatred, took wood and fire, and came up, wishing to burn the house where the Lord’s mother was living with the apostles. And the procurator stood looking at the sight from afar off. And when the people of the Jews came to the door of the house, behold, suddenly a power of fire coming forth from within, by means of an angel, burnt up a great multitude of the Jews. And there was great fear throughout all the city; and they glorified God, who had been born of her. And when the procurator saw what had come to pass, he cried out to all the people, saying: Truly he who was born of the virgin, whom you have thought of driving away, is the Son of God; for these signs are those of the true God. And there was a division among the Jews; and many believed in the name of our Lord Jesus Christ, in consequence of the signs that had come to pass.
And after all these wonderful things had come to pass through the mother of God, and ever-virgin Mary the mother of the Lord, while we the apostles were with her in Jerusalem, the Holy Spirit said to us: You know that on the Lord’s day the good news was brought to the Virgin Mary by the archangel Gabriel; and on the Lord’s day the Saviour was born in Bethlehem; and on the Lord’s day the children of Jerusalem came forth with palm branches to meet him, saying, Hosanna in the highest, blessed is He that comes in the name of the Lord; and on the Lord’s day He rose from the dead; and on the Lord’s day He will come to judge the living and the dead; and on the Lord’s day He will come out of heaven, to the glory and honour of the departure of the holy glorious virgin who brought Him forth.
And on the same Lord’s day the mother of the Lord says to the apostles: Cast incense, because Christ is coming with a host of angels; and, behold, Christ is at hand, sitting on a throne of cherubim. And while we were all praying, there appeared innumerable multitudes of angels, and the Lord mounted upon cherubim in great power; and, behold, a stream of light coming to the holy virgin, because of the presence of her only-begotten Son, and all the powers of the heavens fell down and adored Him. And the Lord, speaking to His mother, said: Mary. And she answered and said: Here am I, Lord. And the Lord said to her: Grieve not, but let your heart rejoice and be glad; for you have found grace to behold the glory given to me by my Father. And the holy mother of God looked up, and saw in Him a glory which it is impossible for the mouth of man to speak of, or to apprehend. And the Lord remained beside her, saying: Behold, from the present time your precious body will be transferred to paradise, and your holy soul to the heavens to the treasures of my Father in exceeding brightness, where there is peace and joy of the holy angels—and other things besides.
And the mother of the Lord answered and said to him: Lay Your right hand upon me, O Lord, and bless me. And the Lord stretched forth His undefiled right hand, and blessed her. And she laid hold of His undefiled right hand, and kissed it, saying: I adore this right hand, which created the heaven and the earth; and I call upon Your much to be praised name Christ, O God, the King of the ages, the only-begotten of the Father, to receive Your handmaid, Thou who deigned to be brought forth by me, in a low estate, to save the race of men through Your ineffable dispensation; do Thou bestow Your aid upon every man calling upon, or praying to, or naming the name of, Your handmaid.
And while she is saying this, the apostles, having gone up to her feet and adored, say: O mother of the Lord, leave a blessing to the world, since you are going away from it. For you have blessed it, and raised it up when it was ruined, by bringing forth the Light of the world. And the mother of the Lord prayed, and in her prayer spoke thus: O God, who through Your great goodness hast sent from the heavens Your only-begotten Son to dwell in my humble body, who hast deigned to be born of me, humble as I am, have mercy upon the world, and every soul that calls upon Your name.
And again she prayed, and said: O Lord, King of the heavens, Son of the living God, accept every man who calls upon Your name, that Your birth may be glorified. And again she prayed, and said: O Lord Jesus Christ, who art all-powerful in heaven and on earth, in this appeal I implore Your holy name; in every time and place where there is made mention of my name, make that place holy, and glorify those that glorify You through my name, accepting of such persons all their offering, and all their supplication, and all their prayer. And when she had thus prayed, the Lord said to His mother: Let your heart rejoice and be glad; for every favour and every gift has been given to you from my Father in heaven, and from me, and from the Holy Spirit: every soul that calls upon your name shall not be ashamed, but shall find mercy, and comfort, and support, and confidence, both in the world that now is, and in that which is to come, in the presence of my Father in the heavens. And the Lord turned and said to Peter: The time has come to begin the singing of the hymn.
And Peter having begun the singing of the hymn, all the powers of the heavens responded with the Alleluiah. And then the face of the mother of the Lord shone brighter than the light, and she rose up and blessed each of the apostles with her own hand, and all gave glory to God; and the Lord stretched forth His undefiled hands, and received her holy and blameless soul. And with the departure of her blameless soul the place was filled with perfume and ineffable light; and, behold, a voice out of the heaven was heard, saying: Blessed are you among women.
And Peter, and I John, and Paul, and Thomas, ran and wrapped up her precious feet for the consecration; and the twelve apostles put her precious and holy body upon a couch, and carried it. And, behold, while they were carrying her, a certain well-born Hebrew, Jephonias by name, running against the body, put his hands upon the couch; and, behold, an angel of the Lord by invisible power, with a sword of fire, cut off his two hands from his shoulders, and made them hang about the couch, lifted up in the air. And at this miracle which had come to pass all the people of the Jews who beheld it cried out: Verily, He that was brought forth by you is the true God, O mother of God, ever-virgin Mary. And Jephonias himself, when Peter ordered him, that the wonderful things of God might be showed forth, stood up behind the couch, and cried out: Holy Mary, who brought forth Christ who is God, have mercy upon me. And Peter turned and said to him: In the name of Him who was born of her, your hands which have been taken away from you, will be fixed on again. And immediately, at the word of Peter, the hands hanging by the couch of the Lady came, and were fixed on Jephonias. And he believed, and glorified Christ, God who had been born of her.
And when this miracle had been done, the apostles carried the couch, and laid down her precious and holy body in Gethsemane in a new tomb. And, behold, a perfume of sweet savour came forth out of the holy sepulchre of our Lady the mother of God; and for three days the voices of invisible angels were heard glorifying Christ our God, who had been born of her. And when the third day was ended, the voices were no longer heard; and from that time forth all knew that her spotless and precious body had been transferred to paradise.
And after it had been transferred, behold, we see Elisabeth the mother of St. John the Baptist, and Anna the mother of the Lady, and Abraham, and Isaac, and Jacob, and David, singing the Alleluiah, and all the choirs of the saints adoring the holy relics of the mother of the Lord, and the place full of light, than which light nothing could be more brilliant, and an abundance of perfume in that place to which her precious and holy body had been transferred in paradise, and the melody of those praising Him who had been born of her— sweet melody, of which there is no satiety, such as is given to virgins, and them only, to hear. We apostles, therefore, having beheld the sudden precious translation of her holy body, glorified God, who had shown us His wonders at the departure of the mother of our Lord Jesus Christ, whose prayers and good offices may we all be deemed worthy to receive, under her shelter, and support, and protection, both in the world that now is and in that which is to come, glorifying in every time and place her only-begotten Son, along with the Father and the Holy Spirit, for ever and ever.
