Explaining a misunderstood term: V. 9. I wrote unto you in an epistle not to company with fornicators; v. 10. yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. V. 11. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner, with such an one no not to eat. V. 12. For what have I to do to judge them also that are without? Do not ye judge them that are within? V. 13. But them, that are without God judgeth. Therefore put away from among yourselves that wicked person.
It was impossible to pursue any avocation at Corinth, without coming into daily contact with immoral, rapacious, idolatrous people. Paul was very well aware of this inevitable intercourse; he was far from suggesting or approving the life of anchorites, hermits, and monks.
But now, in the present epistle, he is couching his admonitions in such language that his meaning is unmistakable. If any one was still in doubt as to the interpretation of the former letter, it would be impossible to mistake his meaning now: If any one calling himself a brother, professing to be a member of the Christian congregation, enrolled as one of their own number, is a fornicator, or avaricious, or an idolater, or a reviler, an abuser of others, or a drunkard, with such a one you should not even eat.
Paul gives only a few examples of flagrant, heinous offenses, which obviously make a person unworthy of belonging to the communion of the Christian brethren. Business transactions a Christian may have with such persons, but to enter into friendly relations of social intimacy with them, to hold fraternal, friendly commerce with men of this stamp, such conduct will never agree with the Christian profession.
So far as the unbelievers are concerned, the Christian congregation has no jurisdiction over them: What business have I to judge those that are without? We Christians know indeed that the unbelievers and gross sinners are under the condemnation of God, and circumstances often arise that we inform them to that effect, but the apostle here speaks of communion, of social intimacy within the congregation, of Christian fellowship.
Since unbelievers are not members of the Christian congregation, the jurisdiction of the congregation does not extend to them. Do not you judge those that are within, while those without God judges? As the Judge of the world, God is taking care of the sentence of those without, of the unbelievers.
So far as the congregation at Corinth is concerned, they should remove the wicked man from their midst, expel him from their communion, and thus preserve the purity of their membership in Christ. The formal expulsion of the malignant sinner must proceed from the congregation as a self-governing body.
Note: The necessity of church discipline is here maintained and must be upheld if the Christian congregation is to fulfill its destiny and purpose.
