A Digression. Paul the Prisoner and his Relation to the Mystery. A knowledge of Paul's story may be presumed among those who read this letter: they will have heard how he was entrusted with the mission of proclaiming to the Gentiles God's dispensation of grace towards them (Ephesians 3:1 f.); it was by revelation, as aforesaid (cf. Ephesians 1:17), that the glorious secret of God was made known to him how fully they can judge for themselves by reading the passage (Ephesians 3:13-21) in which he has already summed it up (Ephesians 3:3 f.). This secret, hidden from former generations, was now revealed in the Spirit to the apostles and prophets of Christ (Ephesians 3:5); it included the admission of the Gentiles to joint-heirship, joint-membership of the Body, joint-participation in the promise through the Good News in Christ Jesus (Ephesians 3:6). Paul, less than the least of all saints, had been made a minister of that gospel through the wondrous working of the Divine grace and power, and entrusted with the task of proclaiming among the Gentiles the inexplorable wealth contained in Christ (Ephesians 3:7 f.). It was his task to enlighten all men by exhibiting the working out of that secret Divine purpose which, from before the beginning of time, had been hidden in God the creator of all things (Ephesians 3:8 f.). The very powers and principalities in heaven had been kept in the dark, and were only now through the Church to learn how many-sided God's wisdom had been (Ephesians 3:10). The whole formed part of God's eternal purpose in Christ Jesus the Church's Lord, who was the source of that bold and fearless access to the Father which believers enjoyed through their confidence in Him (Ephesians 3:11 f.). No need to lose heart when they heard of Paul's sufferings as a prisoner (Ephesians 3:1) on their behalf I Such sufferings were rather a ground of glory (Ephesians 3:13).
Ephesians 3:2. Translate, for surely ye have heard or (if there has been a letter to which this is a reply) since, as ye say, ye have heard. The term dispensation (oikonomia) refers, as in Ephesians 1:10, to the Divine economy of grace, not to the writer's stewardship of it.
Ephesians 3:3. by revelation: only so can the secret of God be made known (cf. Ephesians 1:17). as I wrote afore: according to some in another Pauline epistle perhaps Col. Some even see in it the self-betrayal of an imitator. So again when ye read has been taken to mean when ye read the Scriptures (cf. 1 Timothy 4:13), i.e. either the Pauline letters (supposed, on this hypothesis, to have already become canonical; in which case a late date is required for Eph.) or the OT (so Hort). All these views are needless; the passage means simply, Read what I have written above and judge for yourselves as to my insight into the hidden things of God. The mystery is the whole world-plan of God revealed in Christ; it includes the unity of Jew and Gentile but is not to be limited to that.
Ephesians 3:5. Pre-Christian revelation is not denied, but it is as nothing in comparison with the disclosures now made in Christ. holy apostles: the epithet describes the status of consecration to a particular work, rather than the possession of peculiarly saintly character: but the word may be a reverential gloss inserted by a scribe (perhaps from the parallel Colossians 1:26).
Ephesians 3:10. Jewish thought did not regard the angelic hierarchies as being either omniscient or sinless (cf. 1 Corinthians 2:6-8 *, 1 Corinthians 6:3). The word translated manifold properly means very varied, as of a many-coloured embroidery.
Ephesians 3:11. eternal purpose: lit. purpose of the ages, a Hebraism (cf. Rock of Ages, i.e. everlasting Rock).
