Now I beseech you, brethren, mark them which are causing the divisions and occasions of stumbling, contrary to the doctrine which ye learned: and turn away from them.
And if he refuse to hear them, tell it unto the church: and if he refuse to hear the church also, let him be unto thee as the Gentile and the publican.
Woe unto the world because of occasions of stumbling! for it must needs be that the occasions come; but woe to that man through whom the occasion cometh!
and that because of the false brethren privily brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:
Take heed lest there shall be any one that maketh spoil of you through his philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ:
Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which they received of us.
They went out from us, but they were not of us; for if they had been of us, they would have continued with us: but they went out, that they might be made manifest how that they all are not of us.
