Jesus also said that if they will not listen to you, leave their city or home and shake the dust off your feet.
Paul said, “as much as it is possible,” to live at peace with one another.
It seems that we are fast approaching a time when it is no longer possible to live at peace with them.
good answer as well...
Shaking the dust off one’s feet is a different gesture than burning books. Shaking the dust off one’s feet is to be done after one has made a sincere effort to witness to a particular group, and the gospel has been rejected.
Unless you have evidence that this has occurred with the church in question, there is no reason to believe that principle applies in this particular case.
