May the Lord forever keep the Holy Orthodox Church Unconquerable by the Gates of Hades!
'Remember, O Lord Jesus Christ our God, Thy mercies and compassions which are from the ages, for the sake of which Thou didst become man and didst will to endure crucifixion and death for the salvation of those that rightly believe in Thee; and having risen from the dead didst ascend into the heavens and sittest at the right hand of God the Father, and regardest the humble entreaties of those that call upon Thee with all their heart; incline Thine ear, and hearken unto the humble supplication of me, Thine unprofitable servant, as an odor of spiritual fragrance, which I offer unto Thee for all Thy people. And first, remember Thy Holy, Catholic, and Apostolic Church, which Thou hast provided through Thy precious Blood, and establish, and strengthen, and expand, increase, pacify, and keep Her unconquerable by the gates of hades; calm the dissensions of the churches, quench the raging of the nations, and quickly destroy and uproot the rising of heresy, and bring them to naught by the power of Thy Holy Spirit.

Save, O Lord, and have mercy on the holy Eastern Orthodox patriarchs, most reverend metropolitans, Orthodox archbishops and bishops, and all the priestly and monastic order, and all who serve in the Church, whom Thou hast appointed to shepherd Thy rational flock, and through their prayers have mercy and save me a sinner.

'Save, O Lord, and have mercy on the aged and the young, the poor and the orphans and widows, and those in sickness and sorrow, misfortune and tribulation, those in difficult circumstances and in captivity, in prisons and dungeons, and especially those of Thy servants that are persecuted for Thy sake and the Orthodox Faith by godless peoples, by apostates, and by heretics; and remember them, visit, strengthen, comfort, and by Thy power quickly grant them relief, freedom, and deliverance.

'Illumine with the light of awareness the apostates from the Orthodox Faith, and those blinded by pernicious heresies, and number them with Thy Holy, Apostolic, Catholic Church. Bow'
