1Cor 8:10

“What schoolmaster, without a table of the seven idols, will yet frequent the Quinquatria? The very first payment of every pupil he consecrates both to the honour and to the name of Minerva; so that, even though he be not said "to eat of that which is sacrificed to idols" nominally (not being dedicated to any particular idol), he is shunned as an idolater.”

“What sense is there in discussing the merely accidental, when that on which it rests is to be condemned? Do we believe it lawful for a human oath to be superadded to one divine, for a man to come under promise to another master after Christ, and to abjure father, mother, and all nearest kinsfolk, whom even the law has commanded us to honour and love next to God Himself, to whom the gospel, too, holding them only of less account than Christ, has in like manner rendered honour? Shall it be held lawful to make an occupation of the sword, when the Lord proclaims that he who uses the sword shall perish by the sword? And shall the son of peace take part in the battle when it does not become him even to sue at law? And shall he apply the chain, and the prison, and the torture, and the punishment, who is not the avenger even of his own wrongs? Shall he, forsooth, either keep watch-service for others more than for Christ, or shall he do it on the Lord's day, when he does not even do it for Christ Himself? And shall he keep guard before the temples which he has renounced? And shall he take a meal where the apostle has forbidden him? And shall he diligently protect by night those whom in the day-time he has put to flight by his exorcisms, leaning and resting on the spear the while with which Christ's side was pierced? Shall he carry a flag, too, hostile to Christ? And shall he ask a watchword from the emperor who has already received one from God? Shall he be disturbed in death by the trumpet of the trumpeter, who expects to be aroused by the angel's trump? And shall the Christian be burned according to camp rule, when he was not permitted to burn incense to an idol, when to him Christ remitted the punishment of fire? Then how many other offences there are involved in the performances of camp offices, which we must hold to involve a transgression of God's law, you may see by a slight survey.”

“Let us expand this thought so as to say: "If someone sees you who have knowledge of piety passing the whole day in those senseless and harmful associations, will not the conscience of the weak man be emboldened to pursue such actions more earnestly?" That blessed apostle said this to keep in check those who were heedless, even after having knowledge of piety, who were exposing themselves to places of idolatry and causing scandal to the rest.”

“"For if a man see thee who hast knowledge, sitting at meat in an idol's temple, will not his conscience if he is weak, be emboldened to eat things sacrificed to idols?" After having said, "Take heed lest this your liberty become a stumbling-block," he explains how and in what manner it becomes so: and he continually employs the term "weakness," that the mischief may not be thought to arise from the nature of the thing, nor demons appear formidable. As thus: "At present," saith he, "a man is on the point of withdrawing himself entirely from all idols; but when he sees you fond of loitering about them, he takes the circumstance for a recommendation and abides there himself also. So that not only his weakness, but also your ill-timed behavior, helps to further the plot against him; for it is you who make him weaker."”

“That is: if someone weak sees you, who call yourself perfect, eating food offered to idols, will he not find all the more reason to eat food offered to idols himself, and will he not be even more confirmed (this is what "dispose" means) in the opinion that an idol is something? For, not knowing your thought with which you do this, he will undoubtedly regard your action as an encouragement.”
