I came across a curious phrase from St. Paul in the book of Ephesians. Paul is making reference to the grace and gifts extended to all when he makes mention of the Messiah ascending leading "the captives in his train" (Ps 68:18). Then my translation has the following phrase bracketed.
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.
Sorry no time to look into the Greek or other inter-textual allusions.
