(1) The first fact is Moses own testimony Deuteronomy 12:8 Here we find Moses saying;
"Ye shall not do after all that we do this day every man whatsoever is right in his own eyes.
If an oral law was given at Sinai to explain the written law, Moses would have never made this statement.
(2) In Ezra 3:4 and Nehemiah 8:17 it says they kept the feast of booths as it was written in the Law of Moses and that it had not been kept since the time of Joshua son of Nun. In the Talmud it give specific instruction how to keep Sukkot. If these instructions were orally given at Sinai this feast would not have been lost for 600 years.
(3) Only the Pharisees claimed the oral law was given at Sinai. The Sadducees did not believe in the oral tradition. The Essenes did not follow the oral law. The isolated Jewish communities of Ethiopia and Yemen new nothing of it until the where told they needed to accept it to return to Israel in the last century. If an oral law had been given then the priest of these groups would have surely know of it.
(4) In the oral tradition it has specific instruction for keeping Chanukah the problem with that is, Chanukah is not instituted until 156 B.C. some eleven hundred years after their claim that it was given at Sinai.
(5) Yeshua is critical of the oral traditions in his sermon on the mount. As he is also critical of Chanukah and the priesthood that goes with it. condemning both in parable in the gospel of Matthew. In John he says of those holding that day they are not his disciples.
