1 sn The object of these dimensions is not stated in the text. Interpreters have suggested a variety of referents for this unstated object, including the cross of Christ, the heavenly Jerusalem (which is then sometimes linked to the Church), God’s power, the fullness of salvation given in Christ, the Wisdom of God, and the love of Christ. Of these interpretations, the last two are the most plausible. Associations from Wisdom literature favor the Wisdom of God, but the immediate context favors the love of Christ. For detailed discussion of these interpretive options, see A. T. Lincoln, Ephesians (WBC), 207-13, who ultimately favors the love of Christ.
2 tn The meaning of the participle ἀληθεύοντες (alhqeuonte"; from the verb ἀληθεύω [alhqeuw]) is debated. In classical times the verb could mean “to speak the truth,” or “to be true, to prove true.” In the LXX it appears five times (Gen 20:16; 42:16; Prov 21:3; Isa 44:26; Sir 34:4) and translates four different Hebrew words; there it is an ethical term used of proving or being true, not with the idea of speaking the truth. In the NT the only other place the verb appears is in Gal 4:16 where it means “to speak the truth.” However, in Ephesians the concept of “being truthful” is the best sense of the word. In contrast to the preceding verse, where there are three prepositional phrases to denote falsehood and deceit, the present word speaks of being real or truthful in both conduct and speech. Their deceit was not only in their words but also in their conduct. In other words, the believers’ conduct should be transparent, revealing the real state of affairs, as opposed to hiding or suppressing the truth through cunning and deceit. See H. W. Hoehner, Ephesians, 564-65, and R. Bultmann, TDNT 1:251.
