'Wherefore, if meat causes my brother to stumble, I will eat no flesh for evermore, in order that I do not cause my brother to stumble.'
Paul's conclusion is therefore that he himself would do nothing that might make another stumble. If his eating of meat would cause another to stumble he will never eat of it for evermore. He would do anything rather than make another stumble, for whatever reason. Thus should we also have concern for the weaknesses of the weak, pandering to them so that they may eventually become strong.
