Cosmas Indicopleustes, on Ps 102:20

“Bless the Lord, all ye his angels: you that are mighty in strength, and execute his word, hearkening to the voice of his orders.”

“But these bodies are moved by the invisible Powers in an orderly and rational manner according to the will of God, these Powers having received this as a law, according to what is written in David: Bless the Lord, all ye his angels, ye mighty in strength, that fulfil his word, hearkening unto the voice of his word. Bless the Lord all ye his hosts, ye ministers of his that do his pleasure. To Him be glory for ever and ever, Amen!”
