The reading is from St. Paul's Letter to the Colossians 1:12-18

Brethren, we give thanks to the Father who has qualified us to share in the inheritance of the saints in light. He has delivered us from the dominion of darkness and transferred us to the kingdom of his beloved Son, in whom we have redemption, the forgiveness of sins. He is the image of the invisible God, the first-born of all creation; for in him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or principalities or authorities - all things were created through him and for him. He is before all things, and in him all things hold together. He is the head of the body, the church; he is the beginning, the first-born from the dead, that in everything he might be preeminent.
