What are unorthodox Jews?

Answer 1

Unorthodox Jew is someone of the Jewish faith that believed that Jesus was the son of god. An orthodox Jew believes there is a profet on its way and the Jesus was an imposter

A different answer:

The word "unorthodox" means unusual, and is not normally used in the above way. Rather, a Jew might be called observant or unobservant, religious or non-religious, Orthodox or non-Orthodox.

Answer 2

There is no group of Jews that calls themselves "Unorthodox Jews". However, those Jews that are not Orthodox are typically considered Liberal Jews. Within Liberal Judaism there are a number of movements also distinguished by their level of integration with the non-Jewish World, their styles of prayer, and their level of conservatism. At the most liberal are Secular Jews who may make Jewish foods and sing Jewish songs, but rarely attend synagogue services and do not perform the daily acts required of Orthodox Jews. In Liberal Judaism there is a question as to how much Hebrew and how much Vernacular should be used in a Synagogue Service. Conservative Jews, on the more conservative side typically prefer more Hebrew, whereas Reform Jews prefer more Vernacular. Liberal Jews are often well-acclimated to non-Jewish society and may have many non-Jewish friends and contacts.
