At the time the “Tomb of Mary” was rediscovered, near Mount Zion where the early Christians once lived, the Memory of Mary began to be celebrated – as she herself sang in the Magnificat, “From now on all generations will call me blessed, for the Mighty One has done great things for me, holy is his name.” (Lk 1:48-49). But this wasn’t immediately celebrated as the Feast of the Assumption of the Blessed Virgin Mary but was only celebrated as the “Memory of Mary” in Palestine and later celebrated in Rome as “Dormitio” or “Falling Asleep” of the Mother of God.
Notwithstanding, a belief about the Assumption of Mary was dated to the time of the apostles and rests on the fact that unlike any of the saints whose relics are present and are venerated throughout the Church, there were no relics of Mary to be venerated, and the said “Tomb of Mary” was an empty tomb near the site of her death.
When Emperor Marcian requested for the relics of Mary at the Council of Chalcedon in 451, the Patriarch of Jerusalem responded, “MARY HAD DIED IN THE PRESENCE OF THE APOSTLES; BUT HER TOMB, WHEN OPENED LATER . . . WAS FOUND EMPTY AND SO THE APOSTLES CONCLUDED THAT THE BODY WAS TAKEN UP INTO HEAVEN.”, so there were no relics of her.
And according to the eighth century St. John Damascene, during his homily at the Tomb of Mary, he said of the body of Mary that,
“ALTHOUGH THE BODY WAS DULY BURIED, IT DID NOT REMAIN IN THE STATE OF DEATH, NEITHER WAS IT DISSOLVED BY DECAY. . . . YOU WERE TRANSFERRED TO YOUR HEAVENLY HOME, O LADY, QUEEN AND MOTHER OF GOD IN TRUTH.”
If the apostles were aware of this, why was it not recorded in the Bible?
