Moulton & Milligan — Vocabulary of the Greek NT
σύνσωμος is found in the NT only in Eph 35, and may have been coined by Paul for the occasion. The word is usually understood as ‘‘fellow-member of the body,” i.e. of the Church, but, as Preuschen has pointed out (ZNV7/V i. (1900), p. 85f.), it cannot then be associated with the following gen. τῆς ἐπαγγελίας, nor is there any real sequence of thought in the three epithets συνκληρονόμα.--σύνσωμα--συνμέτοχα. Accordingly, taking σῶμα in its sense of ‘‘slave” (see s.v.), he thinks that we have a term equivalent to σύνδουλος (Col 17, a/.), and that the meaning is that ‘‘the Gentiles are fellow-heirs and fellow-slaves, and so fellow-partakers of the promise.’’
