Jesus quoted the Bible to the Jews that were persecuting him, but told us to beware of the scribes and the Pharisees who knew the truth, but didn't use the truth to be saved.
I simply do not recall reading that Jesus opened his Bible and preached to the masses.
I believe in the teachings of Jesus, as long as I don't have to use Paul to reiterate his teachings. Paul, who murdered Christians, but then magically was transformed on the road to Damascus? No witnesses. And Paul himself said, 1 Corinthians 9:19Though I am free of obligation to anyone, I make myself a slave to everyone, to win as many as possible. 20 To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), to win those under the law. 21To those without the law I became like one without the law (though I am not outside the law of God but am under the law of Christ), to win those without the law.
