5 Bible Verses about Teachers, Of False Doctrines

Brothers, I beg of you to keep your eye on those who stir up dissensions and put hindrances in your way, contrary to the doctrine which you have been taught. Avoid them. Such creatures are no servants of Christ our Lord, they are slaves of their own base desires; with their plausible and pious talk they beguile the hearts of unsuspecting people. But surely not of you!

and men of your own number will arise with perversions of the truth to draw the disciples after them.

and many will follow their immorality (thanks to them the true Way will be maligned);

But in later days, the Spirit distinctly declares, certain people will rebel against the faith; they will listen to spirits of error and to the doctrines that daemons teach

I am astonished you are hastily shifting like this, deserting Him who called you by Christ's grace and going over to another gospel. It simply means that certain individuals are unsettling you; they want to distort the gospel of Christ.
