In 1764, the body of Saint Innocent of Irkutsk was discovered incorrupt during restoration work on the Ascension monastery's Tikhvin church. Many miracles occurred not only at Irkutsk, but also in remote places of Siberia, for those who flocked to the saint with prayer. This moved the Most Holy Synod to uncover the relics and to glorify the saint in the year 1800.
In 1804, a feastday was established to celebrate his memory throughout all Russia on November 26, since the Icon of the Mother of God "of the Sign" is commemorated on the actual day of his repose (November 27). Today we commemorate the uncovering of his relics in 1805.
Troparion - Tone 3
O light most brilliant of the Church:
With rays of goodness you have dawned forth upon this land.
Through many healings of those who approach your tomb with faith,
You gave glory to God.
We beseech you, O holy father, bishop Innocent,
Through your prayers protect this city,
From all misfortune and sorrow! SOURCE:
