“You who boast in the Law, through your breaking the Law, do you dishonor God? ‘THE NAME OF GOD IS BLASPHEMED AMONG THE GENTILES BECAUSE OF YOU,’ just as it is written.””
What worse testament to the world that you serve the One true God then to break the very laws God had given you? This is Paul’s rejection of his readers claim to godliness in connection to the Law. Through the centuries of Israel’s going back and forth between obeying God and breaking His commandments helps us to better understand why Paul is referencing Ezekiel 36:20-21 “When they came to the nations where they went, they profaned My holy name, because it was said of them, ‘These are the people of the LORD; yet they have come out of His land.’ “But I had concern for My holy name, which the house of Israel had profaned among the nations where they went.” The Jew’s boasted in their adherence to the Law, boasted in their reverence to God, boasted in their being the chosen ones and yet they are disciplined and chastised by God for profaning His Holy name by breaking those Laws and their covenant with Him. What mockery they make of the Creator by losing their blessings because of their rebellion. God’s name is smeared in the dirt and looked upon as a synthetic god just as the Gentile gods. God takes so serious the issue of His name being blasphemed. It’s disgusting, it’s undignified and it incurs His righteous anger.
The word blasphemed in the Greek is “blasphemeo” which is related to the railing at that Jesus incurred while on the cross. It’s to speak evil of and to revile against. So, because of the great breach of the Jew’s loyalty to God, God’s name is severely blasphemed among the Gentile nations. This is heavy blow to Paul’s readers as they most likely felt the conviction of the Holy Spirit reveal to them their sin against God.
