² sn The reason why Paul refers to Epaphroditus as his brother, coworker, fellow soldier, etc., is because he wants to build up Epaphroditus in the eyes of the Philippians, since Paul is sending him back instead of Timothy. This accent on Epaphroditus’ character and service is implied in the translation “For he is…”

¹ sn Epaphras is probably a shortened form of the name Epaphroditus. This is probably the same individual whom Paul spoke of as “my brother, coworker, and fellow soldier” in Phil 2:25 (see also Phil 4:18). He is also mentioned in Col 1:7 and 4:12, where he is a founder of the church in Colossae (BDAG 360 s.v. ᾿Επαφρᾶς).

¹ tn Although 1 Cor 3:9 is frequently understood to mean, “we are coworkers with God,” such a view assumes that the genitive θεοῦ (theou) is associative because of its relationship to συνεργοί (sunergoi). However, not only is a genitive of association not required by the syntax (cf. ExSyn 130), but the context is decidedly against it: Paul and Apollos are insignificant compared to the God whom they serve (vv. 5-8).

² tn The ἵνα (hina) clause indicates the result of such support for the traveling missionaries: The Christian who helps to support them in their efforts thus becomes a coworker in cooperation with the truth. Although the dative τῇ ἀληθείᾳ (tē alētheia) is somewhat difficult to specify, it would appear (corresponding to the σύν- [sun-] prefix of the noun modified) to indicate a sense of cooperation with “the truth” which is at work through the missionaries. There is precedent in the Johannine literature for understanding “truth” as personified (John 8:32, “the truth will make you free”; possibly also 1 John 3:19). More explicitly, 1 John 4:6 identifies the Holy Spirit as “the Spirit of Truth,” a characterization repeated in 1 John 5:6. Thus it seems likely that the “truth” at work through the missionaries here is ultimately the Holy Spirit, who works through their efforts. The Christian who supports them thus becomes a coworker with the Spirit of God himself.
