This is so true...
"The Jewish world began changing dramatically, no longer under the authority of God’s Word, but rather, under independent, creative, and man-made interpretation and application. From that point on, the Rabbinical tradition is called the “Oral Law,” and is “canonized” in the Talmud, which is comprised of the Mishna and Gemara. It is imperative to understand the magnitude and breadth of the change that the Jewish world underwent, when we come to talk about keeping or adhering to Jewish tradition. In this same spirit, Paul speaks of Israel’s zeal to establish a righteousness through man-made rules.
Brothers, my heart's desire and prayer to God for them is that they may be saved. For I bear them witness that they have a zeal for God, but not according to knowledge. For, being ignorant of the righteousness of God, and seeking to establish their own, they did not submit to God's righteousness. For Christ is the end of the law for righteousness to everyone who believes" (Rom 10:1–4)."
