How careful is the apostle’s language – ‘If any man that is called a brother’: he professes, he claims to be a brother. Of course, he may not be really, but if he claims to be, and yet he is a fornicator, unrepentant and engaged in that, then he must be put out of the church.
We challenge our hearts. Watch out for covetousness. Watch out for the love of more getting hold of you, looking special, feeling good because of your possessions or your position, ambition for the sake of it. These are very challenging passages.
It is terrible if railing gets into somebody, particularly in marriage. It can do; people can nag at each other and be critical. And the enemy of souls will egg you on, and it will become a habit. Life is crammed full of irritations, and we as people are all potentially irritating to each other. One person likes to put a thing in one place; another person tends to put it in another place. You go and look for that thing, and it is in the place the other person put it. And the devil comes in and lobs a thought into your mind, ‘Isn’t he irritating? Isn’t she irritating? Little by little, he gets you into grumbling, criticising, despising, then expressing it, then becoming highly critical, and then deeply unpleasantness.
But what if he has repented? If a sinner has repented then we may associate with him, but maybe not in the church for a while, because the honour of Christ must still be established. So even if the sinner repents, he may be gated from the church for a while, for a term, that the honour of Christ may be established and everything may be made clear, and he may be further helped. But associating with that person is not under the same rule, ‘not to keep company if anyone who is a brother.’
