Gaius Marius Victorinus : Death is understood in two ways. The first is the familiar definition—when the soul is separated from the body at the end of life. The second is that, while abiding in that same body, the soul pursues the desires of the flesh and lives in sin. — EPISTLE TO THE Ephesians 1.2.1-2 Jerome : [The Greeks] speak of trespass as the first step toward sin. It is when a secret thought steals in, and, though we offer a measure of collusion, it does not yet drive us on to ruin.… But sin is something else. It is when the collusion is actually completed and reaches its goal. — Commentary on Ephesians 2:1-5 John Chrysostom : You observe the gentleness of Paul, and how on all occasions he encourages the hearer, not bearing too hard upon him. For whereas he had said, Ye have arrived at the very last degree of wickedness, (for such is the meaning of becoming dead,) that he may not excessively distress them, (because men are put to shame when their former misdeeds are brought forward, cancelled though they be, and no longer attended with danger,) he gives them, as it were, an accomplice, that it may not be supposed that the work is all their own, and that accomplice a powerful one. And who then is this? The Devil. — Homily on Ephesians 4 John Chrysostom : There is, we know, a corporal, and there is also a spiritual, dying. Of the first it is no crime to partake, nor is there any peril in it, inasmuch as there is no blame attached to it, for it is a matter of nature, not of deliberate choice. It had its origin in the transgression of the first-created man, and thenceforward in its issue it passed into a nature, and, at all events, will quickly be brought to a termination; whereas this spiritual dying, being a matter of deliberate choice, has criminality, and has no termination. — Homily on Ephesians 4 Tertullian : I suppose, forsooth, we find Him, when he speaks of such as "were dead in trespasses and sins, wherein they had walked according to the course of this world, according to the prince of the power of the air, who worketh in the children of disobedience." But Marcion must not here interpret the world as meaning the God of the world. — Against Marcion Book V
