For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in heavenly places.
All Commentaries on Ephesians 6:12 Go To Ephesians 6
Jerome
AD 420
The battle is not against flesh and blood or ordinary temptations. The scene is the war of flesh against spirit. We are being incited to become entrapped in the works of the flesh. … But this is not merely a physical temptation. It is not merely the inward struggle against flesh and blood as such. Rather Satan has cleverly transformed himself into an angel of light. He is striving to persuade us to regard him as a messenger of goodness. This is how he throws his full might into the struggle. He employs deceptive signs and lying omens. He sets before us every possible ruse of evil. Then, when he has so ensnared us that we trust him, he says to us, “Thus says the Lord.” This is not flesh and blood deceiving us. It is not a typical human temptation. It is the work of principalities and powers, the ruler of darkness and spiritual wickedness. .
