Kingdom Gifts

What does this part of a letter from Paul to the believers in Ephesus mean if it is read with the Kingdom in mind rather than the church?

There is one body and one Spirit, just as you were called to one hope at your calling; one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all.

Now grace was given to each one of us according to the measure of the Messiah’s gift. For it says:

When He ascended on high, He took prisoners into captivity;
He gave gifts to people.

But what does “He ascended” mean except that He descended to the lower parts of the earth? The One who descended is the same as the One who ascended far above all the heavens, that He might fill all things. And He personally gave some to be apostles, some prophets, some evangelists, some pastors and teachers, for the training of the saints in the work of ministry, to build up the body of Christ, until we all reach unity in the faith and in the knowledge of God’s Son, growing into a mature man with a stature measured by Christ’s fullness. Then we will no longer be little children, tossed by the waves and blown around by every wind of teaching, by human cunning with cleverness in the techniques of deceit. But speaking the truth in love, let us grow in every way into Him who is the head—Christ. From Him the whole body, fitted and knit together by every supporting ligament, promotes the growth of the body for building up itself in love by the proper working of each individual part.
