a share in common: the stake two parties both hold in one and the same thing
This word shows up once in the whole New Testament. In 2 Corinthians 6:14 Paul asks what share righteousness has with lawlessness. It is not a real question: the expected answer is none, and the point behind it is that none is even possible.
The noun is rare, but the idea behind it was completely ordinary. It is built on a common verb meaning "to have a part in something" (μετέχω), and everyday Greek business papers use the noun for a share in a piece of property or a partnership in a venture. Treaties use it for two cities holding all things in common. So the question carries the force of asking what business these two could possibly do together, what stake either could ever hold in the other.
The verse opens a run of five questions, each pairing two things that cannot be joined, and each reaching for a different word for having something in common:
- this word, a share held jointly, pairing righteousness with lawlessness
- fellowship (κοινωνία), pairing light with darkness
- accord (συμφώνησις), pairing Christ with the figure Paul calls Belial
- the portion that falls to a person (μερίς), pairing a believer with an unbeliever
- going along with something (συγκατάθεσις), pairing the temple of God with idols
Most scholars read the five as near-synonyms varied for the force of the writing rather than as five finely calibrated terms. Where a shade is drawn between the first two, it is that fellowship leans toward the relationship itself while this word leans toward the stake that any partnership assumes.
The word also has a quiet Old Testament connection. The Greek Old Testament uses it for Jerusalem being knit together as a city (Psalm 122:3), translating a Hebrew verb for being joined or allied (חָבַר), and its close relative for a partner regularly stood in for the Hebrew word for a companion (חָבֵר). That zone of being joined to someone fits the paragraph exactly, since Paul opens it with the picture of two mismatched animals harnessed under a single yoke.
What concrete association the μετοχή of 2 Corinthians 6:14 forbids, i.e. the referent of the ἄπιστοι with whom the readers are not to be ἑτεροζυγοῦντες. William Webb catalogues at least twelve proposals, ranging from Qumran-style total separation through litigation before pagan courts to mixed marriage; virtually all commentators exclude ordinary social contact, since 1 Corinthians 5:9-10 rules that out explicitly.
- contestedThe forbidden sharing is cultic: participation in pagan temple meals and idolatry, the same problem addressed in 1 Corinthians 8-10, supported by the temple imagery of 2 Corinthians 6:16 and by the parallel use of μετέχω at 1 Corinthians 10:21 for the table of the Lord over against the table of demons.; Gordon D. Fee, "II Corinthians vi.14-vii.1 and Food Offered to Idols," New Testament Studies 23 (1977): 140-161
- contestedThe ἄπιστοι embrace not only idol-worshipping outsiders but Paul's Judean opponents in Corinth, the rival apostles of chapters 10-13 who advocate a different gospel, so the forbidden partnership is with them.; Philip F. Esler, "Paul's Explanation of Christ-Movement Identity in 2 Corinthians 6:14-7:1: A Social Identity Approach," Biblical Theology Bulletin 51.2 (2021): 101-118; Novum Testamentum 55.1 (2013): 45-60, on the identity of the ἄπιστοι in 2 Corinthians 6:14
Whether 2 Corinthians 6:14-7:1, the paragraph in which this noun stands, is Pauline. Its light/darkness and righteousness/lawlessness dualisms, the name Βελιάρ, the temple imagery, and its concentration of New Testament hapax legomena (μετοχή, συμφώνησις, συγκατάθεσις, ἑτεροζυγέω, μολυσμός) are the central evidence urged on the interpolation side; the lexical oddity of μετοχή is one plank of that stylistic argument.
- majorityPaul wrote the paragraph. The vocabulary argument is weak: the cognate verb μετέχω occurs five times in Paul, the demand for five parallel rhetorical questions itself drives the search for rarer synonyms, 2 Corinthians carries roughly fifty words found nowhere else in the New Testament, and 7:2-4 resumes 6:11-13 in a way that presupposes an intervening unit.; Margaret E.

- minorityThe paragraph is an interpolation of Jewish, probably Qumran-related, character, inserted by a later hand; in its strongest form the thesis holds it to be positively anti-Pauline.; Joseph A.
