10. Now this God is glorified by His Word who is His Son continually,33 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,34 with unceasing voices glorify God; and |80 every created thing that is in the heavens offers glory to God the Father of all.35 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.
34. 5 Origen in his Commentary on Romans (III, § 8) interprets the two Cherubim over the mercy-seat as the Son and the Holy Spirit. In De Principiis (I, Hi. 4, IV, iii. 26) he gives the same interpretation of the two Seraphim of Isa. vi. 3, saying that he received it from his Hebrew teacher: he adds that the same applies to the two living creatures of Hab. iii. 2 (LXX). Philo ( Vit. Mos. iii. 8) had interpreted the two Cherubim as ..., the latter ku&rioj. This probably paved the way for Origen's interpretation.
Irenaeus calls the Cherubim the Son and the Spirit.
