How do knowledge, charity and weak conscience qualify eating?

Concerning things sacrificed to idols, Paul says that they all have knowledge: knowledge puffs up, but charity edifies. The annotation specifies knowledge without charity and humility. Someone who thinks he knows something does not yet know as he ought; someone who loves God is known by him. An idol is nothing in the world and there is one God. Though there are beings called gods in heaven or earth, many gods and lords, the annotation identifies these as those reputed such by the heathen. For the readers there is one God, the Father, from whom all things are and to whom they belong, and one Lord Jesus Christ, through whom all things are and through whom they are.

Not everyone has this knowledge. Some, still conscious of the idol, eat as though the food were sacrificed to it, and their weak conscience is defiled. Meat does not commend them to God: eating gives them no more, and abstaining no less. They should take care lest their liberty perhaps become a stumbling block to the weak. Paul asks whether a weak person who sees someone with knowledge eating in an idol’s temple will be encouraged to eat sacrificed food, and whether the weak brother for whom Christ died will perish through that knowledge. These are conditional warnings, rather than a narrated meal and its result.

Sinning in this way against brethren and wounding their weak conscience is sin against Christ. If meat scandalizes his brother, Paul will never eat flesh, lest he scandalize him. The printed annotation explains scandalizing here as causing the brother to sin. His resolution is conditional on that harm.
