By the Spirit the Father is called Most High and Almighty and Lord of hosts; that we may learn concerning God that He it is who is creator of heaven and earth and all the world, and maker of angels and men, and Lord of all, through whom all things exist and by whom all things are sustained; merciful, compassionate and very tender, good, just.
[…] Now this world is encompassed by seven heavens, in which dwell powers and angels and archangels, doing service to God, the Almighty and Maker of all things: not as though He was in need, but that they may not be idle and unprofitable and ineffectual.
Wherefore also the Spirit of God is manifold in (His) indwelling, and in seven forms of service is He reckoned by the prophet Isaiah, as resting on the Son of God, that is the Word, in His coming as man.
The Spirit of God, he says, shall rest upon him, the Spirit of wisdom and of understanding, the Spirit of counsel and of might, (the Spirit of knowledge) and of godliness; the Spirit of the fear of God shall fill him (Isaiah 11:2f).
Now the heaven which is first from above, and encompasses the rest, is (that of) wisdom; and the second from it, of understanding; and the third, of counsel; and the fourth, reckoned from above, (is that) of might; and the fifth, of knowledge; and the sixth, of godliness; and the seventh, this firmament of ours, is full of the fear of that Spirit which gives light to the heavens.
For, as the pattern (of this), Moses received the seven-branched candlestick, that shined continually in the holy place; for as a pattern of the heavens he received this service, according to that which the Word spake unto him: Thou shalt make (it) according to all the pattern of the things which thou hast seen in the mount (Exodus 25:40).
Now this God is glorified by His Word who is His Son continually, and by the Holy Spirit who is the Wisdom of the Father of all: and the power(s) of these, (namely) of the Word and Wisdom, which are called Cherubim and Seraphim, with unceasing voices glorify God; and every created thing that is in the heavens offers glory to God the Father of all (cf. Rev. 5:13).
He by His Word has created the whole world, and in the world are the angels; and to all the world He has given laws wherein each several thing should abide, and according to that which is determined by God should not pass their bounds, each fulfilling his appointed task.
