What about the rule of Deuteronomy 25:5?
Without the Oral Torah, the Written Torah is nothing but a string of consonants with no vowels or punctuation. Every translation of the Bible into any other language assumes the accuracy of the Oral Torah in getting the vowels and punctuation right. If you are going to reject the Oral Torah, you'll have to throw all your Bible translations away.
You're in someone else's house of worship on this thread. If you wish to dispute or criticize the Oral Torah or the rulings of the Sages, please do so on another thread, not this caucused one.
