Myself rich in godhead, I have come to serve Adam who has become poor, whose form I, the Creator, have willingly put on, and to lay down my life as a ransom for his, I who am impassible in my godhead.

-Troparion from the First Ode of the Canon of Holy Monday

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