Ephesians 4:10

When thou hearest these words, think not of a mere removal from one place to another; for what Paul establishes in the Epistle to the Philippians, that very argument is he also insisting upon here. In the same way as there, when exhorting them concerning lowliness, he brings forward Christ as an example, so does he here also, saying, "He descended into the lower parts of the earth." For were not this so, this expression which he uses, "He became obedient even unto death," were superfluous; whereas from His ascending, he implies His descent, and by "the lower parts of the earth," he means "death," according to the notions of men; as Jacob also said, "Then shall ye bring down my gray hairs with sorrow to the grave." And again as it is in the Psalm, "Lest I become like them that go down into the pit," that is like the dead. Why does he descant upon this region here? And of what captivity does he speak? Of that of the devil; for He took the tyrant captive, the devil, I mean, and death, and the curse, and sin. Behold His spoils and His trophies. "Now this, He ascended, what is it but that He also descended?" This strikes at Paul of Samosata and his school. "He that descended, is the same also that ascended far above all the Heavens, that He might fill all things." He descended, saith he, into the lower parts of the earth, beyond which there are none other: and He ascended up far above all things, to that place, beyond which there is none other. This is to show His divine energy, and supreme dominion. For indeed even of old had all things been filled.
