John Calvin on Colossians 1:17

17. All things were created by him, and for him. He places angels in subjection to Christ, that they may not obscure his glory, for four reasons: In the first place, because they were created by him; secondly, because their creation ought to be viewed as having a relation to him, as their legitimate end; thirdly, because he himself existed always, prior to their creation; fourthly, because he sustains them by his power, and upholds them in their condition. At the same time, he does not affirm this merely as to angels, but also as to the whole world. Thus he places the Son of God in the Highest seat of honor, that he may have the pre-eminence over angels as well as men, and may bring under control all creatures in heaven and in earth.

Colossians 1:18-20

18. And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence:

18. Et ipse est caput corporis Ecclesiae, ipse principium, primogenitus mortuis, ut sit in omnibus ipse primas tenens:

19. For it pleased the Father that in him should all fulness dwell;

19. Quoniam in ipso placuit omnem plenitudinem inhabitare.

20. And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.

20. Et per ipsum reconciliare omnia sibi, pacificando per sanguinem crucis eius, per ipsum, tam quae sunt super terram, quam quae sunt in coelis.
