"The Savior, condescending to the race of mankind..."

The Circumcision of Christ (source)

  
The Savior, condescending to the race of mankind, accepted to be wrapped in swaddling clothes, and did not refuse the circumcision of His flesh, He Who is eight days old from His Mother, but beginningless from the Father. Let us, O faithful, cry out to Him: You are our God, have mercy on us.
-Idiomelon from the Feast of the Circumcision of Christ

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