"What shall we offer to You, O Christ? For You gave us Your Precious Cross..."

The Exaltation of the Precious Cross of Christ (source)

  
What shall we offer to You, O Christ? For You gave us Your Precious Cross to venerate, on which Your All-holy Blood was spilled, and on which Your Flesh was affixed with nails, which we now embrace, giving thanks to You.
  
With hymns, let all of the trees of the forest skip for joy for their fellow tree, beholding the Cross being embraced today, on which Christ lifted up His head, as was foretold by the divine David.
  
You were put to death on the tree that I might find life. O Christ-bearing Cross, my protector unassailable, and mighty strength against the demons, O Cross which we venerate today, we cry out: Sanctify me with your glory.
-from the Matins Canon for the Feast of the Veneration of the Holy Cross

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
