(1Co 11:16) “But if any man seem to be contentious, we have no such custom, neither the churches of God.” There are those who no matter what is taught, are resistant to that which goes against their desires (contentious: fond of strife, thus argumentative). Since we are commanded to seek to be at peace with one another (1 Pet 3:11; Eph 4:3), such a one needs to be simply ignored rather than argued with (“we have no such custom”: habituation; responding as they do in the church).
