October 1 commemorates the transfer of the Terebovlya Icon of the Mother of God from the town of Terebovlya to Lvov in 1672.
This icon of the Most Holy Theotokos originally appeared in the principality of Galich during the time of the Terebovlya princes, in the thirteenth, or perhaps as early as the twelfth century. After the decline of the Galich principality in the thirteenth and fourteenth centuries, Roman Catholics tried many times to seize the icon and bring it to their own church.
The Orthodox believers of Galich and Terebovlya always prayed fervently before the Terebovlya icon, asking the Mother of God to protect them whenever Russia was attacked by enemy forces, and its citizens were led into captivity.
In the spring of 1672, a Turkish army of 300,000 men took the town of Kamenets Podolski. This same army was defeated at Terebovlya, and was forced to retreat. The holy icon of the Mother of God was taken from the Church of the Protection in town and moved to the church in the ancient castle. There the people of Terebovlya thanked God for their deliverance.
On the Feast of the Protecting Veil of the Mother of God in 1672, the Bishop of Lvov, with the clergy and the faithful, transferred the icon to the cathedral of Saint George in Lvov so that it would not be stolen. This translation took place when Bishop Joseph (Shumlyansky) of Lvov, who later became a Uniate, was still a hierarch of the Orthodox Church.
In 1973, when it was decided to celebrate the 300th anniversary of its translation, the icon was provided with a gilded cover, thanks to the efforts of Metropolitan Nicholas of Lvov and Ternopol.
