Tertullian — on Eph 4:8 (Against Marcion Book V)

“I, on my part, now wish to engage with you in a discussion on the allegorical expressions of the apostle. What figures of speech could the novel god have found in the prophets (fit for himself)? "He led captivity captive," says the apostle. With what arms? In what conflicts? From the devastation of what Country? From the overthrow of what city? What women, what children, what princes did the Conqueror throw into chains? For when by David Christ is sung as "girded with His sword upon His thigh," or by Isaiah as "taking away the spoils of Samaria and the power of Damascus," you make Him out to be really and truly a warrior confest to the eye. Learn then now, that His is a spiritual armour and warfare, since you have already discovered that the captivity is spiritual.”
