What Paul says about koinonia reformation is healthy — wholesome. But some don’t consent to it (v. 3). The false teacher’s empty head does not keep him from being full of himself (v. 4). His heart and tongue are tangled — he has questions and verbal clashes. These produce envy, quarrels, verbal hostility, and jumping to conclusions about the motives of others. These men have bent minds and hearts and so they produce bent disputes. They think that piety is supposed to be a means of personal advancement, particularly theirs (v. 5). Get away from such people. This is a wonderful picture of the rabid revolutionary of the early nineteenth century, and it is a vivid picture of some of the people we had to deal with on our slavery controversy.
