Modern conservative Reformed denominations have a huge problem. It used to be that "Reformed" was short for "Reformed According to the Word." Reformed Christians were the loudest to profess to be "Bible-believing Christians."
Now, however, in many circles, "Reformed" appears to be the proudly worn badge of hyper-traditionalists. For them the supreme judge, by which all controversies of religion are to be determined. . . and in whose sentence we are to rest is no longer the Holy Spirit speaking in the Scripture. No. Now all theological controversies are resolved by an appeal to the authority of the decrees of councils, opinions of ancient writers, and doctrines of men.
If you didn't get the irony of my last two sentences, please read the Westminster Confession of Faith, Chapt. 1, par. 10.
Are we followers of Jesus or not? Did Jesus ever once seek to correct the Pharisees or Sadducees by appealing to their traditions or great teachers? No. Just the opposite. He berated them for their loyalty to tradition. He warned them that their traditions "made void the word of God" (Matt. 15:6). He cited the Hebrew Scriptures. Over and over again.
If the reformation of Jesus was anything, it was fresh return to the Hebrew Scriptures as the authority for his church and kingdom.
In Matthew 19:1-12 the Pharisees lay a trap for Jesus. They ask him a question about divorce designed to make him take sides about what tradition school of thought in their little sect was right. Did Jesus know about their internal squabbles about the grounds for a man divorcing a wife? Sure he did. They expected Jesus to say that one side or the other was correct, but he doesn't. When Jesus answered them he did not ask them if they had read this or that Jewish authority on the subject. He asked them, "Have you not read. . ." And then he directed them to the Scriptures, God's Word. He goes all the way back to Genesis, to what God said and God did in the beginning.
Jesus would be derisively labeled as a "biblicist" by many Reformed partisans.
More often than not theological controversies that Christians fight over, that have divided Christian brothers, are best resolved with a fresh look at God's Word. One comes to God's word not looking for a proof text to back one's tradition or confession, but one examines the Bible for fresh insight, new categories, and an authoritative Word that cuts to the heart of the issue. After all, that used to be what it meant to be "Reformed."
