From Hebrews –
3 The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
From Collossians –
He is the image of the invisible God, the firstborn over all creation.
From Luther –
Ah, we poor people, to be so cold and sluggish in the face of the great joy that has clearly been prepared for us! This great benefaction exceeds by far all the other works of creation; and yet our faith in it is found to be so weak, although it is preached and sung to us by angels, who are heavenly theologians and who were so glad for our sake! Their song is very, very beautiful and describes the entire Christian religion. For giving glory to God in the highest heaven is the supreme worship. This they wish and bring to us in the Christ .. Martin Luther quoted in E. M. Plass, WHAT LUTHER SAYS, p.154
And finally Luther –
I have a better Caretaker than you and all the angels. He it is who lies in a manger … but at the same time sits at the right hand of God, the almighty Father. Therefore be at rest. — Martin Luther , letter to his wife Kate: 1546, eleven days before his death.
