Look at this obvious fact. So-and-so is perfectly sure he 'belongs to Christ'? Well then, let him understand, on second thoughts, that I 'belong to Christ' as much as he does.

You put up with it all right, when some interloper preaches a second Jesus (not the Jesus I preached), or when you are treated to a Spirit different from the Spirit you once received, and to a different gospel from what I gave you! Why not put up with me?

I warned you already, on my second visit, and I warn you now before I come, both you who sinned some time ago and the rest of you as well, that I will spare no one if I come back.
