"Knowledge puffs up while love builds up." (1 Corinthians 8:1)
Paul addresses the question of food sacrificed to idols, a major practical issue in the ancient city where most meat sold in the market had been offered at a pagan temple. The Corinthians who are strong in faith and knowledge understand that an idol is nothing, that there is only one God, the Father, from whom all things came and for whom we live, and one Lord Jesus Christ, through whom all things came and through whom we live. Therefore food sacrificed to an idol is just food. Paul does not dispute this theology. But he immediately relativises it: Knowledge puffs up while love builds up. The person who thinks they know something does not yet know as they ought to know. The person who loves God is known by God. The epistemological priority of love over knowledge is one of the great principles of Pauline ethics.
The theological problem is the weak believer whose conscience has not been fully formed. When the weak person, whose conscience is weak, sees the strong eating in an idol's temple, they may be emboldened to eat against their conscience. Their conscience, being weak, is defiled. The weak person is destroyed by the strong person's knowledge. And when you sin against a brother or sister in this way, you sin against Christ. Therefore, Paul concludes, if food causes a brother or sister to fall, he will never eat meat again so as not to cause them to fall. The freedom of the strong is real, but it is subordinated to the love that does not destroy the weak.
Brothers and sisters, knowledge puffs up, love builds up. This single verse judges the entire culture of online theological debate, the parish disputes, the fraternal correction delivered without pastoral tenderness. You may be right. Your knowledge may be accurate. But if the exercise of your rightness destroys a person with a weaker conscience, you have won the argument and lost the brother. Love builds up. Begin there.
Lord God, give us knowledge that serves love and not the reverse. Protect us from the pride of theological correctness that destroys those for whom Christ died. Make us willing to restrict our freedoms for the sake of the weak, as you restricted your own freedom for the sake of all of us. Through Christ our Lord. Amen.
