That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him: In the dispensation of the fullness of times - Εις οικονομιαν του πληρωματος των καιρων. The word οικονομια, which is the same as our word economy, signifies, as Dr. Macknight has well observed, "the plan which the master of a family, or his steward, has established for the management of the family;" it signifies, also, a plan for the management of any sort of business: and here it means the dispensation of the Gospel, that plan by which God has provided salvation for a lost world; and according to which he intends to gather all believers, both Jews and Gentiles, into one Church under Jesus Christ, their head and governor. See the note on Matthew 24:45, where the word and the office are particularly explained.
The fullness of times - By this phrase we are to understand either the Gospel dispensation, which is the consummation of all preceding dispensations, and the last that shall be afforded to man; or that advanced state of the world which God saw to be the most proper for the full manifestation of those benevolent purposes which he had formed in himself relative to the salvation of the world by Jesus Christ.
That he might gather together in one - Ανακεφαλαιωσασθαι, from ανα, again, and κεφαλαιοω, to reduce to one sum; to add up; to bring different sums together, and fractions of sums, so as to reduce them under one denomination; to recapitulate the principal matters contained in a discourse. Here it means the gathering together both Jews and Gentiles, who have believed in Christ, into one Church and flock. See the preceding note.
All things - which are in heaven, and which are on earth - This clause is variously understood: some think, by things in heaven the Jewish state is meant and by things on earth the Christian. The Jews had been long considered a Divine or heavenly people; their doctrine, their government, their constitution, both civil and ecclesiastical, were all Divine or heavenly: as the powers of the heavens, Matthew 24:29, Luke 21:26, mean the Jewish rulers in Church and state, it is very possible that the things which are in heaven mean this same state; and as the Gentiles were considered to have nothing Divine or heavenly among them, they may be here intended by the earth, out of the corruption of which they are to be gathered by the preaching of the Gospel. But there are others who imagine that the things in heaven mean the angelical hosts; and the things on earth believers of all nations, who shall all be joined together at last in one assembly to worship God throughout eternity. And some think that the things in heaven mean the saints who died before Christ's advent, and who are not to be made perfect till the resurrection, when the full power and efficacy of Christ shall be seen in raising the bodies of believers and uniting them with their holy souls, to reign in his presence for ever. And some think that, as the Hebrew phrase שמים והארץ shamayim vehaarets, the heavens and the earth, signifies all creatures, the words in the text are to be understood as signifying all mankind, without discrimination of peoples, kindreds, or tongues; Jews, Greeks, or barbarians. All that are saved of all nations, (being saved in the same way, viz. by faith in Christ Jesus, without any distinction of nation or previous condition), and all gathered into one Church or assembly.
I believe that the forming one Church out of both Jews and Gentiles is that to which the apostle refers. This agrees with what is said, Ephesians 2:14-17.
