“Each mature Christian has, of course, the responsibility to ‘test all things.’ But Christian truth is a corporate possession. The church is the context within which we should expect to have wrong ideas gently corrected and right ones gently suggested, and where we in turn may contribute to the same activities. This will mean active membership in a local church and perhaps a variety of Christian groups; it should also involve careful listening to Christians of other backgrounds and periods of history” (N.T. Wright, Colossians and Philemon, vol. 12, Tyndale New Testament Commentaries, gen. ed. Leon Morris,  43).
