'Give no occasions of stumbling, either to Jews, or to Greeks, or to the church of God, even as I also please all men in all things, not seeking my own profit, but the profit of the many, that they may be saved.'
For what should be their first concern is to give no occasion for tripping up or stumbling to anyone, whether Jew, or Gentile, or Christian. They are to be like Paul is, not seeking his own advantage or gain, but concerned to be rightfully pleasing and satisfactory to all men, living so as to present to them the best witness and the clearest testimony, so that they might profit, and, best of all, be saved (see 1 Corinthians 9:19-23).
Note the wide range of those who could be affected by the act of knowingly eating meat sacrificed in a temple to idols, each for different reasons, the Jew because the idea is abhorrent to all to which he has been brought up, the Gentile because he judges the eater as giving credence to idols, and the believer because it can raise doubts within him that can be harmful, and even destroy him.
