Now about food sacrificed to idols: We know that "We all possess knowledge." But knowledge puffs up while love builds up. Those who think they know something do not yet know as they ought to know. But whoever loves God is known by God. (1 Corinthians 8:1-3)
If we are to be the sorts of people that can engage our changing world with the wisdom and grace of God, we need to be the sorts of people formed into the likeness of God, namely that of Christ Jesus. This is the "growth to maturity" as Christians that Paul talks about elsewhere. It is the formation of Christian character.
In 1 Corinthians 8, Paul shows us how this works with the character trait of love. "Knowledge puffs up while love builds up," he says.
Now, among the clear stances of scripture is the well-deliberated and discerned opinion of the Jerusalem Council in Acts 15 that Gentile believers were to, "abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality."
Paul, upon receiving a question from the Corinthians about food sacrificed to idols then, could have simply reiterated this position of the council, stated "it's clear," and told the Corinthians to obey or else. But he doesn't. It is not the principles of knowledge and obedience that are to be the primary drivers of action in the Corinthian community, but love.
Paul offers a case study. He begins by stating, in effect, that the decision of the Jerusalem Council was wrong when it comes to the capital "T" "Truth" about God. "We know," he says, that an idol is nothing and that there is no God but one. So: "we are no worse if we do not eat, and no better if we do."
But, he continues, "if someone with a weak conscience sees you, with all your knowledge, eating in an idol's temple… this brother or sister, for whom Christ died, is destroyed by your knowledge." This, he says, is a sin against Christ. Now Paul is back in alignment with the Council, and the reason is that Love demands something different than Truth here. And the demand of love is what wins.
Knowledge on its own—even the knowledge of the deepest and truest articles of orthodox Christian belief—leads to pride and the tearing down and "destruction" of many things, including the faith of "weaker brothers and sisters" (vv. 9-11). Knowledge on its own is an "immature" knowledge. A knowledge that does not yet know as it ought.
Love, however, takes a different path and starts in a different place. Love begins with relationship—a love of God. One can know all sorts of things about God without really loving God or having a relationship with him, which is why knowledge is not sufficient.
When someone loves God, it is evidence to them that they are known by God. Their love for God only comes because they have received his prior love for them in Christ. There is a natural humility that arises from this awareness. I only love because God first loved me, a sinner. I am only saved because God has saved me. All Christians stand on this same foundation: not that we know God or have somehow learned enough about him, grabbed hold of him, or acted well enough in response to him, but rather that God has known, loved, and grabbed hold of us—sinners though we (still) are.
The primary driver of action in the maturing community of Christ then, is a love modeled on God's own. We are to lovingly honour the sister and brother for whom Christ died not just as a fellow image-bearer worthy of dignity, but as a family member intimately known and loved by the same God who loves us. To do this is to know God (1 John 4:7-21) in the intimate relationship sort of knowing the Hebrew scriptures speak of. This is a mature knowing—a knowing as we ought.
Truth can only be spoken in a love like this, and indeed as this case in Corinthians shows—sometimes Love determines that some greater Truths of God's Sovereignty are left unsaid and unshown for the sake of building another up in faith and not tearing them down. This quite clearly takes much maturity to apply well.
So, try it out. Practice Christ's love today. How might you lovingly build one another up in Christian faith, rather than tear down?
