Give none offense, neither to the Jews, nor to the Gentiles, nor to the church of God:
Read Chapter 10
Offense is given to the Jews when they see that a Christian, who claims the inheritance of the law and the prophets, is not afraid of idols, which they detest. Offense is given to the Greeks, that is, to the Gentiles, if their sin of idolatry is not only not contested but actually encouraged by people in the church who fail to reject things sacrificed to idols. Commentary on Paul’s Epistles.
Do not be a stumbling block in any way to those you meet. Be cheerful, a lover of the brethren, gentle, humble. Do not demean the aim of hospitality by seeking extravagant foods. Be content with what is at hand.
Do all things decently and according to order for the purpose of edification. The person, the time, the need and the place all should be properly chosen and determined upon. By consideration of all these details every shadow of evil suspicion will be avoided.

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 do you put to flight those whom you ought to draw to you? Since even Gentiles are hurt, when they see us reverting to such things: for they know not our mind nor that our soul has come to be above all pollution of sense.
