In Newsweek, Rabbi Jacob Neusner writes about how he would respond to Jesus had he met him personally 2,000 years ago:

I can see myself not only meeting and arguing with Jesus, challenging him on the basis of our shared Torah, the Scriptures Christians would later adopt as the "Old Testament." I can also imagine myself saying, "Friend, you go your way, I'll go mine, I wish you well—without me. Yours is not the Torah of Moses, and all I have from God, and all I ever need from God, is that one Torah of Moses."

We would meet, we would argue, we would part friends—but we would part. He would have gone his way, to Jerusalem and the place he believed God had prepared for him; I would have gone my way, home to my wife and my children, my dog and my garden. He would have gone his way to glory, I my way to my duties and my responsibilities….

Only the Torah is the word of God. I think Christianity, beginning with Jesus, took a wrong turn in abandoning the Torah. By the truth of the Torah, much that Jesus said is wrong. By the criterion of the Torah, Israel's religion in the time of Jesus was authentic and faithful, not requiring reform or renewal, demanding only faith and loyalty to God and the sanctification of life through carrying out God's will. Jesus and his disciples took one path, and we another. I do not believe God would want it any other way.
