Is God against knowledge? We can see that is not what Paul is talking about here, because elsewhere in Scripture it says:
The heart of him who has understanding seeks knowledge, but the mouth of fools feeds on foolishness. Pro 15:14
For the earth will be filled with the knowledge of the glory of the Lord, as the waters cover the sea. Hab 2:14
Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord, as His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue, by which have been given to us exceedingly great and precious promises, that through these you may be partakers of the divine nature, having escaped the corruption that is in the world through lust. But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge, to knowledge self-control, to self-control perseverance, to perseverance godliness, to godliness brotherly kindness, and to brotherly kindness love. 2 Pet 1:2-7
The issue in question facing the church was whether someone, eating meat sacrificed to an idol, had broken the commandment to not commit idolatry. We have to remember that in the 1st century of the Roman Empire, where Corinth was, every butcher shop in the Empire procured its meat from the temples of the idols and the false pagan gods. There was no meat that had not been first offered to an idol as an animal sacrifice. So this created a dilemma among the formerly pagan believers in Jesus outside of Judea: if we eat meat which has been offered to an idol, are we breaking the commandment, Do not commit idolatry? This is a gray area, a dispute over a doubtful thing (Rom 14:1).
The short answer is, No, idolatry is not being committed, but … are you loving your brother by not putting a stumbling block in front of him? If you do not worship idols because you love God, then you certainly ought to love your brother because you love God – you ought not to put a stumbling block in front of him. Someone can have superior knowledge of the proper application of Torah in all matters, and still violate Torah, if they allow Knowledge rather than Love to determine their decisions. Love is the fulfilling of the Torah!
