The whole armor, panoplia, is as though one manifold spiritual weapon, so closely joined in its parts that nothing can be set aside from it.
One must put on not one weapon, but all the weapons, in order to guard oneself from every side. At the same time, as soon as one makes a movement, one should immediately come upon some weapon.
These weapons are called God’s because they have been indicated and appointed by God, are given by God, and are strong through God. Through them God conquers the enemy by us.
One must be armed with all the weapons, because if any one is lacking, standing against the enemy is doubtful. Therefore the Apostle says: That you may be able to stand, pros to dynasthai, for the sake of being able to stand.
As soon as there is no weapon, or some weapon is lacking, then it is fitting not to stand, but to flee or surrender.
To stand means to go out to the struggle, to take one’s position in battle. Or, since the battle proceeds without ceasing, it means to stand in such a position fearlessly, face to face with the enemy.
Or it means not only to stand, but to withstand, so that you may be able to yield to the enemy in nothing.
Against the wiles of the devil. Wiles, methodeiai, means circuitous approaches. The Apostle encourages them, speaking as though this were his meaning: the enemy is not strong; he succeeds only by cunning.
Among us also people say: such a one got around me. The chief snare of the enemy is to present in thoughts as true what is false. In deeds and undertakings he presents as good what is evil.
In aspirations he carries men away by deceptive hopes. He knows how to present all this in such a way that the inattentive man falls into the nets and becomes entangled.
In this respect, to stand is inseparable from being watchful. Stand and look keenly in every direction. If you do not miss your moment, the enemy will accomplish nothing.
Saint Chrysostom says: “He did not say, Stand against battles, against wars, but against wiles. For our enemy does not wage war against us simply and openly, but with deceit.
What is deceit? To be deceitful means to entice and deceive by cunning. This happens in words, in deeds, and in struggle, when we happen to have dealings with deceivers.
The enemy never proposes obvious sins. Rather, in his deceit, he arranges this otherwise. Using pretexts, he presents a respectable reason.
By this the Apostle encouraged the soldiers and made them sober, urging them to caution. He wishes not to weaken the soldiers who oppose the enemy, the devil, but to move them against him.
By speaking of the enemy’s devices, he thereby teaches attentiveness. If he had shown them the power of the enemies and stopped at this, he would have brought them to despondency.
On the contrary, both before and after this he shows that it is possible to overcome the enemy. By this very fact he especially encourages them.”
Theodoret also points to certain wiles: “The Apostle called the enemy’s devices wiles, for he often prepares vice under the appearance of virtue.
In some cases, for example, he mixes vainglory with fasting, prayer, and care for the needy. Into chastity he inserts blameworthy conceit.”
Blessed Jerome sets forth other hostile wiles. “If he does not succeed,” he says, “in drawing one away by lust, he proposes avarice.
If he does not succeed in capturing by this, he leads one to make the belly into a god. In general he acts like skillful commanders. When he notices a weak side in a man, he directs all his forces there.
He does this with the thought that, once he has gained possession of the weak side, he will also take the strong into his hands.”
