1 Corinthians 10:29

"Conscience, I say, not thine own, but the other's." But perhaps some one may say, "The brethren indeed, as is natural, thou sparest, and dost not suffer us to taste for their sakes, lest their conscience being weak might be emboldened to eat the idol sacrifices. But if it be some heathen, what is this man to thee? Was it not thine own word, 'What have I to do with judging them that are without?' Wherefore then dost thou on the contrary care for them?" "Not for him is my care," he replies, "but in this case also for thee." To which effect also he adds, "For why is my liberty judged by another conscience?" meaning by "liberty," that which is left without caution or prohibition. For this is liberty, freed from Jewish bondage. And what he means is this: "God hath made me free and above all reach of injury, but the Gentile knoweth not how to judge of my rule of life, nor to see into the liberality of my Master, but will condemn and say to himself, Christianity is a fable; they abstain from the idols, they shun demons, and yet cleave to the things offered to them: great is their gluttony." "And what then?" it may be said. "What harm is it to us, should he judge us unfairly?" But how much better to give him no room to judge at all! For if thou abstain, he will not even say this. "How," say you, "will he not say it? For when he seeth me not making these inquiries, either in the shambles or in the banquet; what should hinder him from using this language and condemning me, as one who partakes without discrimination?" It is not so at all. For thou partakest, not as of idol-sacrifices, but as of things clean. And if thou makest no nice enquiry, it is that thou mayest signify that thou fearest not the things set before thee; this being the reason why, whether thou enterest a house of Gentiles or goest into the market, I suffer thee not to ask questions; viz. lest thou become timid and perplexed, and occasion thyself needless trouble.
