On Demonic Opposition

Zec. 3:1-3 And the Lord showed me Joshua the high priest standing before the Angel of the Lord, and the Devil stood on his right hand to resist him. And the Lord said to the Devil, The Lord rebuke you, O Devil, even the Lord that has chosen Jerusalem rebuke you. Behold, is not this as a brand plucked from the fire?

St. John of Karpathos ca. 7th cent.

Keep in mind that high priest at whose right hand the devil stood, opposing all his good thoughts and words and actions (cf. Zech. 3:1). Then you will not be astonished at what happens to yourself. (For the Encouragement of the Monks in India 74)
