From September 15 until the Leavetaking, we sing "O come, let us worship and fall down before Christ. O son of God crucified in the flesh, save us who sing to Thee: Alleluia" at weekday Liturgies following the Little Entrance.
Troparion - Tone 1 O Lord, save Your people, And bless You inheritance. Grant victories to the Orthodox Christians Over their adversaries. And by virtue of Your Cross, Preserve Your habitation.
Kontakion - Tone 4 As You were voluntarily raised upon the cross for our sake, Grant mercy to those who are called by Your Name, O Christ God; Make all Orthodox Christians glad by Your power, Granting them victories over their adversaries, By bestowing on them the Invincible trophy, Your weapon of Peace.
