This is why it says: “When he ascended on high, he took many captives and gave gifts to his people.”
(What does “he ascended” mean except that he also descended to the lower, earthly regions ?
He who descended is the very one who ascended higher than all the heavens, in order to fill the whole universe.)
So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers,
to equip his people for works of service, so that the body of Christ may be built up
until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
