According to Holy Tradition, the Entrance of the Most Holy Theotokos into the Temple took place in the following manner. The parents of the Virgin Mary, Saints Joachim and Anna, praying for an end to their childlessness, vowed that if a child were born to them, they would dedicate it to the service of God.
When the Most Holy Virgin reached the age of three, the holy parents decided to fulfill their vow. They gathered together their relatives and acquaintances, and dressed the All-Pure Virgin in Her finest clothes. Singing sacred songs and with lighted candles in their hands, virgins escorted Her to the Temple (Psalm 45:14-15). There the High Priest and several priests met the handmaiden of God. In the Temple, fifteen high steps led to the sanctuary, which only the priests and High Priest could enter. The child Mary, so it seemed, could not make it up this stairway. But just as they placed Her on the first step, strengthened by the power of God, She quickly went up the remaining steps and ascended to the highest one. Then the High Priest, through inspiration from above, led the Most Holy Virgin into the Holy of Holies, where only the High Priest entered once a year to offer a purifying sacrifice of blood. Therefore, all those present in the Temple were astonished at this most unusual occurrence.
After entrusting their child to the Heavenly Father, Joachim and Anna returned home. The All-Holy Virgin remained in the quarters for virgins near the Temple. According to the testimony of Holy Scripture (Exodus 38; 1 Kings 1: 28; Luke 2: 37), and also the historian Josephus Flavius, there were many living quarters around the Temple, in which those who were dedicated to the service of God dwelt.
The earthly life of the Most Holy Theotokos from Her infancy until She was taken up to Heaven is shrouded in deep mystery. Her life at the Jerusalem Temple was also a secret. “If anyone were to ask me,” said Saint Jerome, “how the Most Holy Virgin spent the time of Her youth, I would answer that that is known to God Himself and the Archangel Gabriel, Her constant guardian.”
But there are accounts in Church Tradition, that during the All-Pure Virgin’s stay at the Temple, She grew up in a community of pious virgins, diligently read the Holy Scripture, occupied Herself with handicrafts, prayed constantly, and grew in love for God. From ancient times, the Church has celebrated the Feast of the Entry of the Most Holy Theotokos into the Temple. Indications that the Feast was observed in the first centuries of Christianity are found in the traditions of Palestinian Christians, which say that the holy Empress Helen built a church in honor of the Entry of the Most Holy Theotokos into the Temple.
Saint Gregory of Nyssa, in the fourth century, also mentions this Feast. In the eighth century Saints Germanus and Tarasius, Patriarchs of Constantinople, delivered sermons on the Feast of the Entry.
The Feast of the Entrance of the Most Holy Theotokos into the Temple foretells God’s blessing for the human race, the preaching of salvation, the promise of the coming of Christ.
Today is the prelude of the good will of God,
of the preaching of the salvation of mankind.
The Virgin appears in the temple of God,
in anticipation proclaiming Christ to all.
Let us rejoice and sing to her,
"Rejoice, O Fulfillment of the Creator's dispensation."
The most pure Temple of the Savior,
the precious Chamber and Virgin,
the sacred Treasure of the glory of God,
is presented today to the house of the Lord.
She brings with her the grace of the Spirit;
therefore, the angels of God praise her,
“Truly this woman is the abode of heaven.”
