Christ Himself as the Armor of God. Jerome: From
what we read of the Lord our Savior throughout the Scriptures, it is manifestly
clear that the whole armor of Christ is the Savior himself. It is he whom we
are asked to “put on.” It is one and the same thing to say “Put on the whole
armor of God” and “Put on the Lord Jesus Christ.” Our belt is truth and our
breastplate is righteousness. The Savior is also called both “truth” and
“righteousness.” So no one can doubt that he himself is that very belt and breastplate.
On this principle he is also to be understood as the “preparation of the gospel
of peace.” He himself is the “shield of faith” and the “helmet of salvation.”
He is the “sword of the Spirit,” because he is the Word of God, living and
efficacious, the utterance of which is stronger than any helmet and sharp on
both sides. Epistle to the Ephesians
Who Must Fight in This Battle? Theodoret: In ordinary battles the generals do not arm women or children or the aged. But our general, Christ the Lord, distributes this royal armory to all alike. He then teaches them the stratagems of the devil. This is what he means by the devil’s wiles. Epistle to the Ephesians 6.11.
6:12a Contending Against Principalities
It Is Not Flesh and Blood That Deceive. Jerome: 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. Epistle to the Ephesians 3.6.11.
