John Chrysostom

"Give no occasion of stumbling, either to Jews, or to Greeks, or to the Church of God:" i.e., give no handle to anyone: since in the case supposed, both thy brother is offended, and the Jew will the more hate and condemn thee, and the Gentile in like manner deride thee even as a gluttonous man and a hypocrite.

Not only, however, should the brethren receive no hurt from us, but to the utmost of our power not even those that are without. For if we are "light," and "leaven," and "luminaries," and "salt," we ought to enlighten, not to darken; to bind, not to loosen; to draw to ourselves the unbelievers, not to drive them away. Why then puttest thou to flight those whom thou oughtest to draw to thee? Since even Gentiles are hurt, when they see us reverting to such things: for they know not our mind nor that our Soul hath come to be above all pollution of sense. And the Jews too, and the weaker brethren, will suffer the same.

Seest thou how many reasons he hath assigned for which we ought to abstain from the idol-sacrifices? Because of their unprofitableness, because of their needlessness, because of the injury to our brother, because of the evil-speaking of the Jew, because of the reviling of the Gentile, because we ought not to be partakers with demons, because the thing is a kind of idolatry.
