Which is why only the authentic Jewish Tradition can interpret the Bible.
The official body to decide such matters hasn't sat for about 1700 years. 1930 years if you don't count the post-Temple period.
What capacity does any individual Jew have to decide what is or is not in accord with tradition? What is or is not authentic? Rabbis have their opinions. Sometimes they even contradict each other. But only the duly constituted Sanhedrin decides for good. And until it does, the field is open.
You don't get much more authentic than Jesus and His disciples - ALL Jews! However, we have the witness of another Jew, Saul of Tarsus, who adamantly set out, filled with great religious fervor, to stop the spread of theis 'christian heresy'.
Acts 9:1-5, "But Saul, still breathing threats of slaughter against the disciples of the Lord, went to the high priest and asked him for letters to the synagogues at Damascus, that if he found any men or women belonging to this Way (a word used for Christianity), he might bring them in bonds to Jerusalem. And as he went on his journey, it came to pass that he drew near to Damascus, when suddenly a light from heaven shone round about him; and falling to the ground, he heard a voice saying to him, "Saul, Saul, why dost thou persecute me?" And he said, "Who art thou Lord?" And He said, "I am Jesus whom thou art persecuting.""
