It is better for us to suppose that through so many turns of speech only this is expressed: whatever one may think necessary in the act of creation is all in the Creator Son, manifested by Him, and placed into the work of creation.
God the Son created all things Himself, by His own power and for Himself. Nothing assisting from outside entered here.
All things were created by Him, that is, by Him as the Firstborn just mentioned, and, still higher, as the Son of God.
The work of creation is the work of the tri-hypostatic God, Father, Son, and Holy Spirit, indivisibly. Athanasius the Great repeatedly expresses this thus: all things were created by the Father in the Son through the Holy Spirit.
Or again, by the Father through the Son in the Holy Spirit. Therefore the Father is Creator, the Son is Creator, and the Holy Spirit is Creator. Yet there are not three Creators, but one Creator.
The prophet David confesses this thus: By the word of the Lord the heavens were established, and by the Spirit of His mouth all their host (cf. Ps 33:6).
If in the writings of the New Testament we meet more places where creation is ascribed to the Son, this is because the holy Apostles had the greatest need to prove the divinity of the Lord Jesus Christ.
He is the incarnate Son of God. In Him the visible human nature concealed His invisible Godhead. The strongest proof of divinity is creative power. For He who creates from nothing is the Existing One.
His essence is to be, containing in Himself the whole fullness of perfections. So also in the present Epistle, the Apostle needed to set before them the divine majesty of Christ the Savior.
He therefore says that by Him, as Son of God and God, all things were created. Of course, in his mind he does not exclude the Father and the Holy Spirit.
Let us note here that all attempts to determine what exactly belonged to the Son in the work of creation should not be regarded as deserving full agreement, respect, and attention.
For example, such expressions are considered to explain much: that the Son is, in the work of creation, causa instrumentalis or causa exemplaris.
By the first, it is meant that the Son is the instrument of creation. By the second, that He, as Wisdom, is the holder of the ideas of all creatures.
Both expressions seem to explain something, but both remove the Son from creative action. If the Son is an instrument, then He does not create, but the Father creates by Him.
If He is only the holder of ideas, then He appears as something at rest, not acting. Besides, is it reasonable to say that, among persons of God equal in all things, one is the instrument of another?
And is it fitting to think that the ideas of creatures are only in the Son, and not also in the Father and the Holy Spirit?
If they are also in Them, then why philosophize and say the Son is causa exemplaris? If it is fitting to apply the work of creation to the activity of our soul, then let each consider how the soul acts.
Whatever it does, it always works with all its powers: intellect, will, and feeling. But if you begin to analyze and divide what belongs to which power in the work, you will not be able to distinguish it precisely.
If even in our own action we cannot discover such distinctions, how shall we devise what belongs to which Person in the work of the tri-hypostatic God?
This is all the more so because the likeness of three powers in the one soul to the three hypostases in the one God is extremely weak. Yet it may be considered when reflecting on God, because the image of God is in the soul.
All things means all that exists. Then he enumerates: what is in heaven and on earth, that is, the earth with all its creatures, and heaven with all that exists in it.
Then, since at the phrase what is in heaven someone might limit his thought only to the sun, moon, and stars, while the Apostle needed to indicate not only this, he added, visible and invisible.
It is as though he were saying: I do not mean this alone, but also what is hidden in them. I mean not only the visible world, but also the invisible, spiritual world.
Finally, so that no one would exclude anyone in this world of spirits from the number of those created by God the Son, the Apostle lists their hosts by name: whether thrones, dominions, principalities, or powers.
He concludes: all things were created by Him and in Him. Everything, everything you might imagine and recognize as existing, all was created by Him.
Saint Paul especially needed to fix attention on this invisible world of the heavenly spiritual powers. The false teachers who were tempting the Colossians speculated about them improperly and placed Christ, Jesus, the Son, in their rank.
The Apostle says that the Lord Jesus Christ, the incarnate Son of God, is not only not numbered among them. On the contrary, He is their Creator and God.
He lists only four of their hosts, we must suppose, merely by way of example. One may add: these and all their other hosts, whatever they are.
There was no need to enumerate all the angelic ranks. The discourse is not about them, but about the divinity of the Lord and Savior, which is proved above all by creative power.
Having said, all things were created by Him and in Him, the Apostle makes it understood that nothing remains uncreated by Him, except, of course, the Spirit who proceeds from the Father. See blessed Theophylact.
