1-corinthians 5:10

For then must ye needs go out of the world - What an awful picture of the general corruption of manners does this exhibit! The Christians at Corinth could not transact the ordinary affairs of life with any others than with fornicators, covetous persons, extortioners, railers, drunkards, and idolaters, because there were none others in the place! How necessary was Christianity in that city!

Yet not altogether ... - In my direction not "to company" with them, I did not mean that you should refuse all kinds of contact with them; that you should not treat them with civility, or be engaged with them in any of the transactions of life, or in the ordinary contact of society between man and man, for this would be impossible - but that you should not so associate with them as to be esteemed to belong to them, or so as to be corrupted by their example. You are not to make them companions and friends.

With the fornicators - Most pagans were of this description, and particularly at Corinth. See the introduction to this Epistle.

Of this world - Of those who are out of the church; or who are not professed Christians.

Or with the covetous - The avaricious; those greedy of gain. Probably his direction in the former epistle had been that they should avoid them.

Or extortioners - Rapacious persons; greedy of gain, and oppressing the poor, the needy, and the fatherless, to obtain money.

Or an idolater - All the Corinthians before the gospel was preached there worshipped idols.

Then must ye needs ... - It would be necessary to leave the world. The world is full of such persons. You meet them everywhere. You cannot avoid them in the ordinary transactions of life, unless you either destroy yourselves, or withdraw wholly from society. This passage shows:

(1) That that society was full of the licentious and the covetous, of idolaters and extortioners. (Compare the notes at Romans 1.)

(2) that it is not right either to take our own lives to avoid them, or to withdraw from society and become monks; and therefore, that the whole monastic system is contrary to Christianity; and,

(3) That it is needful we should have some contact with the people of the world; and to have dealings with them as neighbors, and as members of the community. "How far" we are to have contact with them is not settled here. The general principles may be:

(1) That it is only so far as is necessary for the purposes of good society, or to show kindness to them as neighbors and as members of the community.

(2) we are to deal justly with them in all our transactions.

(3) we may be connected with them in regard to the things which "we have in common" - as public improvements, the business of education, etc.

(4) we are to endeavor to do them good, and for that purpose we are not to shun their society. But,

5:10 But I did not mean that you should altogether refrain from conversing with heathens, though they are guilty in some of these respects. Covetous, rapacious, idolaters - Sinners against themselves, their neighbour, God. For thenye must go out of the world - Then all civil commerce must cease.So that going out of the world, which some account a perfection, St. Paul accounts an utter absurdity.
