Troparion of the Protection Tone 4
Most holy Mother of God,/ today we Orthodox joyfully celebrate thy coming among us./ As we gaze at thy icon we cry with compunction:/ Shelter us under thy protection, deliver us from evil,/ and pray thy Son Christ our God to save our souls.
Kontakion of the Protection Tone 3
Today the Virgin is standing before us in the Church/ praying for us with the choirs of Saints./ Angels worship with Hierarchs,/ Apostles rejoice with Prophets,/ for the Mother of God intercedes with the Eternal God for us.
From the OCA website:
The Protection of the Most Holy Theotokos: “Today the Virgin stands in the midst of the Church, and with choirs of Saints she invisibly prays to God for us. Angels and Bishops venerate Her, Apostles and prophets rejoice together, Since for our sake she prays to the Eternal God!”
This miraculous appearance of the Mother of God occurred in the mid-tenth century in Constantinople, in the Blachernae church where her robe, veil, and part of her belt were preserved after being transferred from Palestine in the fifth century.
On Sunday, October 1, during the All Night Vigil, when the church was overflowing with those at prayer, the Fool-for-Christ St Andrew (October 2), at the fourth hour, lifted up his eyes towards the heavens and beheld our most Holy Lady Theotokos coming through the air, resplendent with heavenly light and surrounded by an assembly of the Saints. St John the Baptist and the holy Apostle John the Theologian accompanied the Queen of Heaven. On bended knees the Most Holy Virgin tearfully prayed for Christians for a long time. Then, coming near the Bishop’s Throne, she continued her prayer.
After completing her prayer she took her veil and spread it over the people praying in church, protecting them from enemies both visible and invisible. The Most Holy Lady Theotokos was resplendent with heavenly glory, and the protecting veil in her hands gleamed “more than the rays of the sun.” St Andrew gazed trembling at the miraculous vision and he asked his disciple, the blessed Epiphanius standing beside him, “Do you see, brother, the Holy Theotokos, praying for all the world?” Epiphanius answered, “I do see, holy Father, and I am in awe.”
