ISB ~ Ephesians 4 v9 - 10
A parenthetical explanation of how Jesus fulfills Ps 68. Interpretations differ over the meaning of lower parts of the earth. (1) Some view this expression as a reference to earth itself, to which Christ descended in his Incarnation (Jn 3:13). (2) Others take it to mean the underworld, to which Jesus descended on Holy Saturday before rising again on Easter Sunday. The second view is more likely correct in light of similar expressions in the Greek versions of Ps 63:9 and 139:15 that clearly refer to the underworld of the dead. In this case, Paul is stressing that Christ has charted the extremities of the cosmos, descending to its deepest depths in his Passion and rising above its highest heights at his Ascension. This is not simply a journey through space; rather, it is an expression of Christ’s supreme humiliation and exaltation.
• Several Church Fathers connected this verse with Christ’s descent to the dead, in which he released the captive souls of the righteous and led them up to heaven (1 Pet 3:18-19; CCC 632-33).
