O Christ our God, Your Kingdom is eternal and Your dominion is from generation to generation. You have become incarnate of the Holy Spirit, being made Man through the ever-virgin Mary. Your coming, O Christ, has shed upon us a great light. O You, Light of Light and Radiance of the Father! You have illuminated the whole creation. Wherefore everything that breathes sings to You a hymn of praise. O image of the Father’s glory, eternal God, existing before all ages, who shone forth from the Virgin. O Lord, glory to You. Help me to prepare myself to truly celebrate this great mystery. I ask your help and   offer praise to You, Father, Son and Holy Spirit, now and ever and forever. Amen.
