‘By the word of the Lord the heavens were established; and all the power of them by the spirit of his mouth’ (Psalm 32:6).
Where are those who set at naught the Spirit? Where are those who separate It from the creative power?
Where are those who dissever It from union with the Father and Son?
Let them hear the psalm which says: ‘By the word of the Lord the heavens were established; and all the power of them by the spirit of his mouth’.
The term ‘Word’ will not be considered as this common form of diction which consists of names and expressions, nor will the Spirit be considered as vapor poured out in the air;
but as the Word, which was in the beginning with God (John 1:1), and as the Holy Spirit, which has obtained this appellation as Its own.
As, then, the Creator, the Word, firmly established the heavens, so the Spirit which is from God, which proceeds from the Father, that is, which is from His mouth (that you may not judge that It is some external object or some creature, but may glorify It as having Its substance from God) brings with It all the powers in Him.
Therefore, all the heavenly power was established by the Spirit; that is, it has from the assistance of the Spirit the solidity and firmness and constancy in holiness and in every virtue that is becoming to the sacred powers.
In this place, therefore, the Spirit was described as from His mouth; we shall find elsewhere that the Word also was said to be from His mouth, in order that it may be understood that the Savior and His Holy Spirit are from the Father.
Since, then, the Savior is the Word of the Lord, and the Holy Spirit is the Spirit from His mouth, both joined with Him in the creation of the heavens and the powers in them, and for this reason the statement was made: ‘By the word of the Lord the heavens were established; and all the power of them by the spirit of his mouth’.
For, nothing is made holy, except by the presence of the Spirit. The Word, the Master Craftsman and Creator of the universe, gave entrance into existence to the angels; the Holy Spirit added holiness to them.
The angels were not created infants, then perfected by gradual exercise and thus made worthy of the reception of the Spirit; but, in their initial formation and in the material, as it were, of their substance they had holiness laid as a foundation.
Wherefore, they are turned toward evil with difficulty, for they were immediately steeled by sanctity, as by some tempering, and possessed steadfastness in virtue by the gift of the Holy Spirit.
