In Paul's context, he was admonishing some of the men in responsible positions in the early congregation, who evidently began taking little advantages..they felt important in the position they held...they felt that it entitled them to a little more than the ordinary member of the congregation deserved...they allowed themselves special privileges, and they expected things of a material nature from the brothers so that they could live a little easier, they could be looked up to as being somebody of importance...that was all they wanted, at first but gradually they and their successors in office became more demanding, more bold, more arbitrary in expressing authority...they deceived and misled the congregation in order to gratify their own selfish desires and "exploited them with counterfeit words"...
Peter also spoke of such men within the congregation...
"Also, they will greedily exploit you with counterfeit words. But their judgment, decided long ago, is not moving slowly, and their destruction is not sleeping." 2 Peter 2:3
As did Jude in Jude 4...
"My reason is that certain men have slipped in among you who were long ago appointed to this judgment by the Scriptures; they are ungodly men who turn the undeserved kindness of our God into an excuse for brazen conduct and who prove false to our only owner and Lord, Jesus Christ."
Paul's admonition has stark warning for us today...do not suffer fools who misuse/misunderstand God's Word for their own selfish purposes...
