1 Corinthians 9:19For though I be free from all men, yet have I made myself servant unto all, that I might gain the more.
Romans 14:15-21But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died. Let not then your good be evil spoken of: For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost. For he that in these things serveth Christ is acceptable to God, and approved of men. Let us therefore follow after the things which make for peace, and things wherewith one may edify another. For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence. It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
1 Corinthians 8:9-13But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak. For if any man see thee which hast knowledge sit at meat in the idol's temple, shall not the conscience of him which is weak be emboldened to eat those things which are offered to idols; And through thy knowledge shall the weak brother perish, for whom Christ died? But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ. Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend.
1 Corinthians 10:32Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:
2 Corinthians 8:21Providing for honest things, not only in the sight of the Lord, but also in the sight of men.
