The Beheading of St. John the Forerunner (Source)

  
O Forerunner of the Savior, you censured the king that he might not work lawlessness, through the games of a lawless woman, but Herod fell upon you and cut off your head. Because of this, your name is praised from the rising of the sun until its setting. As one having boldness before the Lord, entreat ceaselessly that our souls be saved.
-Doxastikon of the Aposticha from the Feast of the Beheading of the Precious Forerunner

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