From the ethical point of view, eating is something completely neutral, but not all believers have the same level of theological knowledge, which is why Paul exhorts, then, some new converts were not sure of the power of their ancient pagan gods; others did not know that idols had no influence on their lives.
Human knowledge exhibits two limitations: it tends to focus on itself, and can not serve as a foundation for interpersonal relationships. The duties of love are the determining factor in questions of moral significance, since the principle of love limits freedom of the individual conscience, and we must take into account that, although an idol is nothing like the simple product of the human imagination, some of the so-called gods, are demonic beings that operate in the middle of the worship of idols.
Therefore @relicuary and beloved community, we must be careful with the idolotria, because there is only one God, lord of the universe, which we must worship for ever and ever.
