What does Ephesians 1:21 Mean?

Verse Meaning

Christ"s ascension has resulted in His exaltation over every other authority (cf. Colossians 1:16), human and angelic (cf. Philippians 2:8-11), present and future (cf. 1 Corinthians 15:23-28). The Jews believed angels controlled human destiny, but Paul saw Jesus Christ doing this. The rule, authority, power, and dominion in view are probably descriptions of evil angelic rulers. [1]

Context Summary

Ephesians 1:15-23 - What The Heart May Receive
It is well to go over the successive links of this golden chain when we are in our secret chamber, appropriating them one by one and asking whether we have received a spirit of wisdom and revelation to know Christ, and whether the eyes of our heart have been enlightened to know the hope, the riches, the glory, and the greatness of His power. In so far as we yield ourselves to the strength of God's might, He will raise us from the grave of selfishness and cause us to sit with Christ in the place of spiritual life and power.
Notice the emphasis with which the Apostle affirms the supremacy of Christ's nature, Ephesians 1:21-22. This is a psalm of ascension. We can almost follow His tracks, as all the evil powers which rule the darkness of this world drop far beneath Him. The ascending Lord is high over all, and if we claim our right as members of His glorified body, we also shall stand above all our spiritual adversaries; and it is easier to descend on an enemy from above him than to seek to assail him from beneath. Notice that Christ needs the Church as much as the head needs the body, because it is through the Church that He fulfills Himself. Ask Him to fill all of you with all of Him. [source]

Chapter Summary: Ephesians 1

1  After Paul's salutation,
3  and thanksgiving for the Ephesians,
4  he treats of our election,
6  and adoption by grace;
11  which is the true and proper fountain of man's salvation
13  And because the height of this mystery cannot be easily attained unto,
16  he prays that they may come to the full knowledge and possession thereof in Christ

Greek Commentary for Ephesians 1:21

Far above all rule [υπερανω πασης αρχης]
Late compound adverbial preposition (υπερ ανω — huperαιωνι — anō) with the ablative case. In N.T. only here and Hebrews 9:5. As in Colossians 1:16, so here Paul claims primacy for Jesus Christ above all angels, aeons, what not. These titles all were used in the Gnostic speculations with a graduated angelic hierarchy. [source]
World [aiōni)]
“Age.” See this identical expression in Matthew 12:32 for the present time (Galatians 1:4; 1 Timothy 6:17) and the future life (Ephesians 2:7; Luke 20:35). Both combined in Mark 10:30; Luke 18:30. [source]
Far above [ὑπεράνω]
Lit., over above. See on Ephesians 1:19. Connect with made Him to sit. [source]
Principality, power, etc. []
These words usually refer to angelic powers; either good, as Ephesians 3:10; Colossians 1:16; Colossians 2:10; or bad, as Ephesians 6:12; 1 Corinthians 15:24; Colossians 2:15; or both, as Romans 8:38. See on Colossians 1:16; see on Colossians 2:15. Here probably good, since the passage relates to Christ's exaltation to glory rather than to His victory over evil powers. [source]
And every name that is named []
And has a collective and summary force - and in a word. Every name, etc. Whatever a name can be given to. “Let any name be uttered, whatever it is, Christ is above it; is more exalted than that which the name so uttered affirms” (Meyer). Compare Philemon 2:9. “We know that the emperor precedes all, though we cannot enumerate all the ministers of his court: so we know that Christ is placed above all, although we cannot name all” (Bengel). [source]
Not only in this world, etc. []
Connect with which is named. For world ( αἰῶνι ), see on John 1:9. [source]

Ephesians 1:19 Exceeding [ὑπερβάλλον]
Compounds with ὑπέρ overbeyond, are characteristic of Paul's intensity of style, and mark the struggle of language with the immensity of the divine mysteries, and the opulence of the divine grace. See Ephesians 1:21; Ephesians 3:20; 2 Corinthians 4:17, etc. [source]
Ephesians 4:10 Far above [υπερανω]
See note on Ephesians 1:21. All the heavens (παντων των ουρανων — pantōn tōn ouranōn). Ablative case after υπερανω — huperanō For the plural used of Christ‘s ascent see note on Hebrews 4:14 and note on Hebrews 7:27. Whether Paul has in mind the Jewish notion of a graded heaven like the third heaven in 2 Corinthians 12:2 or the seven heavens idea one does not know. That he might fill all things This purpose we can understand, the supremacy of Christ (Colossians 2:9.). [source]
Philippians 3:21 Subdue [ὑποτάξαι]
Rev., subject. See on James 4:7. It is more than merely subdue. It is to bring all things within His divine economy; to marshal them all under Himself in the new heaven and the new earth in which shall dwell righteousness. Hence the perfected heavenly state as depicted by John is thrown into the figure of a city, an organized commonwealth. The verb is thus in harmony with Phlippians 3:20. The work of God in Christ is therefore not only to transform, but to subject, and that not only the body, but all things. See 1 Corinthians 15:25-27; Romans 8:19, Romans 8:20; Ephesians 1:10, Ephesians 1:21, Ephesians 1:22; Ephesians 4:10. [source]
Philippians 2:9 A name []
Rev., correctly, the name. This expression is differently explained: either the particular name given to Christ, as Jesus or Lord; or name is taken in the sense of dignity or glory, which is a common Old-Testament usage, and occurs in Ephesians 1:21; Hebrews 1:4. Under the former explanation a variety of names are proposed, as Son of God, Lord, God, Christ Jesus. The sense of the personal name Jesus seems to meet all the conditions, and the personal sense is the simpler, since Jesus occurs immediately after with the word name, and again Jesus Christ in Phlippians 2:11. The name Jesus was bestowed on Christ at the beginning of His humiliation, but prophetically as the One who should save His people from their sins, Matthew 1:21. It was the personal name of others besides; but if that is an objection here, it is equally an objection in Phlippians 2:10. The dignity is expressed by above every name. He bears the name in His glory. See Acts 9:5. See on Matthew 1:21. [source]
Colossians 1:16 Thrones, dominions, principalities, powers [θρόνοι, κυριότητες, ἀρχαὶ, ἐξουσίαι]
Compare Ephesians 1:21; Ephesians 3:10; Ephesians 6:12; 1 Corinthians 15:24; Romans 8:38; Colossians 2:10, Colossians 2:15; Titus 3:1. In Titus 3:1, they refer to earthly dignities, and these are probably included in 1 Corinthians 15:24. It is doubtful whether any definite succession of rank is intended. At any rate it is impossible to accurately define the distinctions. It has been observed that wherever principalities ( ἀρχαὶ ) and powers ( ἐξουσίαι ) occur together, principalities always precedes, and that δύναμις power(see Ephesians 1:21) when occurring with either of the two, follows it; or, when occurring with both, follows both. The primary reference is, no doubt, to the celestial orders; but the expressions things on earth, and not only in this world in the parallel passage, Ephesians 1:21, indicate that it may possibly include earthly dignities. Principalities and powers are used of both good and evil powers. See Ephesians 3:10; Ephesians 6:12; Colossians 2:15. The passage is aimed at the angel-worship of the Colossians (see Introduction); showing that while they have been discussing the various grades of angels which fill the space between God and men, and depending on them as media of communion with God, they have degraded Christ who is above them all, and is the sole mediator. Compare Hebrews 1:5-14, where the ideas of the Son as Creator and as Lord of the angels are also combined. Thrones occurs only here in enumerations of this kind. It seems to indicate the highest grade. Compare Revelation 4:4, θρόνοι thronesA.V. seats, and see note. Thrones here probably means the enthroned angels. Dominions or dominations, also Ephesians 1:21. Principalities or princedoms. In Romans 8:38, this occurs without powers which usually accompanies it. [source]
1 Thessalonians 4:16 Archangel [ἀρχαγγέλου]
Only here and Judges 1:9. Not in O.T. The Pauline angelology shows traces of Rabbinical teachings in the idea of orders of angels. See Ephesians 1:21; Colossians 1:16; Romans 8:38. The archangels appear in the apocryphal literature. In the Book of Enoch (see on Judges 1:14) four are named, Michael, Uriel, Raphael, and Gabriel. Michael is set over the tree which, at the time of the great judgment, will be given over to the righteous and humble, and from the fruit of which life will be given to the elect. In Revelation href="/desk/?q=re+8:2&sr=1">Revelation 8:2. See also on Judges 1:9, and comp. Daniel 12:1. [source]
2 Thessalonians 1:9 Glory of his power [δόξης τῆς ἰσχύος αὐτοῦ]
For glory see on 1 Thessalonians 2:12. Ἱσχὺς powernot often in Paul. It is indwelling power put forth or embodied, either aggressively or as an obstacle to resistance: physical power organized or working under individual direction. An army and a fortress are both ἰσχυρὸς. The power inhering in the magistrate, which is put forth in laws or judicial decisions, is ἰσχὺς , and makes the edicts ἰσχυρὰ validand hard to resist. Δύναμις is the indwelling power which comes to manifestation in ἰσχὺς The precise phrase used here does not appear elsewhere in N.T. In lxx, Isaiah 2:10, Isaiah 2:19, Isaiah 2:21. The power ( δύναμις ) and glory of God are associated in Matthew 24:30; Mark 13:26; Luke 21:27; Revelation 4:11; Revelation 19:1. Comp. κράτος τῆς δόξης αὐτοῦ strengthof his glory, Colossians 1:11. Additional Note on ὄλεθρον αἰώνιον eternaldestruction, 2 Thessalonians 1:9 Ἁιών transliterated eon is a period of time of longer or shorter duration, having a beginning and an end, and complete in itself. Aristotle ( περὶ οὐρανοῦ , i. 9,15) says: “The period which includes the whole time of each one's life is called the eon of each one.” Hence it often means the life of a man, as in Homer, where one's life ( αἰών ) is said to leave him or to consume away (Il. v. 685; Od. v. 160). It is not, however, limited to human life; it signifies any period in the course of events, as the period or age before Christ; the period of the millennium; the mytho-logical period before the beginnings of history. The word has not “a stationary and mechanical value” (De Quincey). It does not mean a period of a fixed length for all cases. There are as many eons as entities, the respective durations of which are fixed by the normal conditions of the several entities. There is one eon of a human life, another of the life of a nation, another of a crow's life, another of an oak's life. The length of the eon depends on the subject to which it is attached. It is sometimes translated world; world representing a period or a series of periods of time. See Matthew 12:32; Matthew 13:40, Matthew 13:49; Luke 1:70; 1 Corinthians 1:20; 1 Corinthians 2:6; Ephesians 1:21. Similarly οἱ αἰῶνες theworlds, the universe, the aggregate of the ages or periods, and their contents which are included in the duration of the world. 1 Corinthians 2:7; 1 Corinthians 10:11; Hebrews 1:2; Hebrews 9:26; Hebrews 11:3. -DIVIDER-

The word always carries the notion of time, and not of eternity. It always means a period of time. Otherwise it would be impossible to account for the plural, or for such qualifying expressions as this age, or the age to come. It does not mean something endless or everlasting. To deduce that meaning from its relation to ἀεί is absurd; for, apart from the fact that the meaning of a word is not definitely fixed by its derivation, ἀεί does not signify endless duration. When the writer of the Pastoral Epistles quotes the saying that the Cretans are always ( ἀεί ) liars (Titus 1:12), he surely does not mean that the Cretans will go on lying to all eternity. See also Acts 7:51; 2 Corinthians 4:11; 2 Corinthians 6:10; Hebrews 3:10; 1 Peter 3:15. Ἁεί means habitually or continually within the limit of the subject's life. In our colloquial dialect everlastingly is used in the same way. “The boy is everlastingly tormenting me to buy him a drum.”-DIVIDER-
In the New Testament the history of the world is conceived as developed through a succession of eons. A series of such eons precedes the introduction of a new series inaugurated by the Christian dispensation, and the end of the world and the second coming of Christ are to mark the beginning of another series. See Ephesians 3:11. Paul contemplates eons before and after the Christian era. Ephesians 1:21; Ephesians 2:7; Ephesians 3:9, Ephesians 3:21; 1 Corinthians 10:11; comp. Hebrews 9:26. He includes the series of eons in one great eon, ὁ αἰὼν τῶν αἰώνων theeon of the eons (Ephesians 3:21); and the author of the Epistle to the Hebrews describes the throne of God as enduring unto the eon of the eons (Hebrews 1:8). The plural is also used, eons of the eons, signifying all the successive periods which make up the sum total of the ages collectively. Romans 16:27; Galatians 1:5; Philemon 4:20, etc. This plural phrase is applied by Paul to God only. -DIVIDER-

The adjective αἰώνιος in like manner carries the idea of time. Neither the noun nor the adjective, in themselves, carry the sense of endless or everlasting. They may acquire that sense by their connotation, as, on the other hand, ἀΐ̀διος , which means everlasting, has its meaning limited to a given point of time in Judges 1:6. Ἁιώνιος means enduring through or pertaining to a period of time. Both the noun and the adjective are applied to limited periods. Thus the phrase εἰς τὸν αἰῶνα , habitually rendered forever, is often used of duration which is limited in the very nature of the case. See, for a few out of many instances, lxx, Exodus 21:6; Exodus 29:9; Exodus 32:13; Joshua 14:9; 1 Samuel 8:13; Leviticus 25:46; Deuteronomy 15:17; 1 Chronicles 28:4. See also Matthew 21:19; John 13:8; 1 Corinthians 8:13. The same is true of αἰώνιος . Out of 150 instances in lxx, four-fifths imply limited duration. For a few instances see Genesis 48:4; Numbers 10:8; Numbers 15:15; Proverbs 22:28; Jonah 2:6; Habakkuk 3:6; Isaiah 61:8. -DIVIDER-
-DIVIDER-
Words which are habitually applied to things temporal or material can not carry in themselves the sense of endlessness. Even when applied to God, we are not forced to render αἰώνιος everlastingOf course the life of God is endless; but the question is whether, in describing God as αἰώνιος , it was intended to describe the duration of his being, or whether some different and larger idea was not contemplated. That God lives longer than men, and lives on everlastingly, and has lived everlastingly, are, no doubt, great and significant facts; yet they are not the dominant or the most impressive facts in God's relations to time. God's eternity does not stand merely or chiefly for a scale of length. It is not primarily a mathematical but a moral fact. The relations of God to time include and imply far more than the bare fact of endless continuance. They carry with them the fact that God transcends time; works on different principles and on a vaster scale than the wisdom of time provides; oversteps the conditions and the motives of time; marshals the successive eons from a point outside of time, on lines which run out into his own measureless cycles, and for sublime moral ends which the creature of threescore and ten years cannot grasp and does not even suspect. -DIVIDER-
-DIVIDER-
There is a word for everlasting if that idea is demanded. That αἰώνιος occurs rarely in the New Testament and in lxx does not prove that its place was taken by αἰώνιος . It rather goes to show that less importance was attached to the bare idea of everlastingness than later theological thought has given it. Paul uses the word once, in Romans 1:20, where he speaks of “the everlasting power and divinity of God.” In Romans 16:26he speaks of the eternal God ( τοῦ αἰωνίου θεοῦ ); but that he does not mean the everlasting God is perfectly clear from the context. He has said that “the mystery” has been kept in silence in times eternal ( χρόνοις αἰωνίοις ), by which he does not mean everlasting times, but the successive eons which elapsed before Christ was proclaimed. God therefore is described as the God of the eons, the God who pervaded and controlled those periods before the incarnation. To the same effect is the title ὁ βασιλεὺς τῶν αἰώνων theKing of the eons, applied to God in 1 Timothy 1:17; Revelation 15:3; comp. 2Timothy href="/desk/?q=2ti+1:9&sr=1">2 Timothy 1:9; Titus 1:2), cannot mean before everlasting times. To say that God bestowed grace on men, or promised them eternal life before endless times, would be absurd. The meaning is of old, as Luke 1:70. The grace and the promise were given in time, but far back in the ages, before the times of reckoning the eons. -DIVIDER-
-DIVIDER-
Ζωὴ αἰώνιος eternallife, which occurs 42 times in N.T., but not in lxx, is not endless life, but life pertaining to a certain age or eon, or continuing during that eon. I repeat, life may be endless. The life in union with Christ is endless, but the fact is not expressed by αἰώνιος . Κόλασις αἰώνιος , rendered everlasting punishment (Matthew 25:46), is the punishment peculiar to an eon other than that in which Christ is speaking. In some cases ζωὴ αἰώνιος does not refer specifically to the life beyond time, but rather to the eon or dispensation of Messiah which succeeds the legal dispensation. See Matthew 19:16; John 5:39. John says that ζωὴ αἰώνιος is the present possession of those who believe on the Son of God, John 3:36; John 5:24; John 6:47, John 6:64. The Father's commandment is ζωὴ αἰώσιος , John 12:50; to know the only true God and Jesus Christ is ζωὴ αἰώνιος , John 17:3. -DIVIDER-
-DIVIDER-
Bishop Westcott very justly says, commenting upon the terms used by John to describe life under different aspects: “In considering these phrases it is necessary to premise that in spiritual things we must guard against all conclusions which rest upon the notions of succession and duration. 'Eternal life' is that which St. Paul speaks of as ἡ ὄντως ζωὴ thelife which is life indeed, and ἡ ζωὴ τοῦ θεοῦ thelife of God. It is not an endless duration of being in time, but being of which time is not a measure. We have indeed no powers to grasp the idea except through forms and images of sense. These must be used, but we must not transfer them as realities to another order.”-DIVIDER-
Thus, while αἰώνιος carries the idea of time, though not of endlessness, there belongs to it also, more or less, a sense of quality. Its character is ethical rather than mathematical. The deepest significance of the life beyond time lies, not in endlessness, but in the moral quality of the eon into which the life passes. It is comparatively unimportant whether or not the rich fool, when his soul was required of him (Luke 12:20), entered upon a state that was endless. The principal, the tremendous fact, as Christ unmistakably puts it, was that, in the new eon, the motives, the aims, the conditions, the successes and awards of time counted for nothing. In time, his barns and their contents were everything; the soul was nothing. In the new life the soul was first and everything, and the barns and storehouses nothing. The bliss of the sanctified does not consist primarily in its endlessness, but in the nobler moral conditions of the new eon, - the years of the holy and eternal God. Duration is a secondary idea. When it enters it enters as an accompaniment and outgrowth of moral conditions. -DIVIDER-
-DIVIDER-
In the present passage it is urged that ὄλεθρον destructionpoints to an unchangeable, irremediable, and endless condition. If this be true, if ὄλεθρος isextinction, then the passage teaches the annihilation of the wicked, in which case the adjective αἰώνιος is superfluous, since extinction is final, and excludes the idea of duration. But ὄλεθρος does not always mean destruction or extinction. Take the kindred verb ἀπόλλυμι todestroy, put an end to, or in the middle voice, to be lost, to perish. Peter says, “the world being deluged with water, perished ” ( ἀπολοῦνται 2 Peter 3:6); but the world did not become extinct, it was renewed. In Hebrews 1:11, Hebrews 1:12quoted from Isaiah href="/desk/?q=isa+51:6&sr=1">Isaiah 51:6, Isaiah 51:16; Isaiah 65:17; Isaiah 66:22; 2 Peter 3:13; Revelation 21:1. Similarly, “the Son of man came to save that which was lost ” ( ἀπολωλός ), Luke 19:10. Jesus charged his apostles to go to the lost ( ἀπολωλότα ) sheep of the house of Israel, Matthew 10:6, comp. Matthew 15:24. “He that shall lose ( ἀπολέσῃ ) his life for my sake shall find it,” Matthew 16:25. Comp. Luke 15:6, Luke 15:9, Luke 15:32. -DIVIDER-
-DIVIDER-
In this passage the word destruction is qualified. It is “destruction from the presence of the Lord and from the glory of his power, “ at his second coming, in the new eon. In other words, it is the severance, at a given point of time, of those who obey not the gospel from the presence and the glory of Christ. Ἁιώνιος may therefore describe this severance as continuing during the millennial eon between Christ's coming and the final judgment; as being for the wicked prolonged throughout that eon and characteristic of it, or it may describe the severance as characterizing or enduring through a period or eon succeeding the final judgment, the extent of which period is not defined. In neither case is αἰώνιος to be interpreted as everlasting or endless.sa180 [source]

Jude 1:8 Dominion - dignities [κυριότητα - δόξας]
It is not easy to determine the exact meaning of these two terms. Κυριότης , dominion, occurs in three other passages, Ephesians 1:21; Colossians 1:16; 2 Peter 2:10. In the first two, and probably in the third, the reference is to angelic dignities. Some explain this passage and the one in Peter, of evil angels. In Colossians the term is used with thrones, principalities, and powers, with reference to the orders of the celestial hierarchy as conceived by Gnostic teachers, and with a view to exalt Christ above all these. Glories or dignities is used in this concrete sense only here and at 2 Peter 2:10. [source]
Jude 1:6 First estate [ἀρχὴν]
The word originally signifies beginning, and so frequently in New Testament, mostly in the Gospels, Acts, Hebrews, Catholic Epistles, and Apocalypse. From this comes a secondary meaning of sovereignty, dominion, magistracy, as being the beginning or first place of power. So mostly by Paul, as principalities (Romans 8:38); rule (1 Corinthians 15:24). Compare Luke 12:11, magistrates; Rev., rulers; and Luke 20:20, power. Rev., rule. A peculiar use of the word occurs at Acts 10:11, “the sheet knit at the four corners ( ἀρχαῖς );” the corners being the beginnings of the sheet. In this passage the A. V. has adopted the first meaning, beginning, in its rendering first estate. Rev. adopts the second, rendering principality. The Jews regarded the angels as having dominion over earthly creatures; and the angels are often spoken of in the New Testament as ἀρχαί , principalities; as Romans 8:38; Ephesians 1:21; so that this term would be appropriate to designate their dignity, which they forsook.
