Although Jesus could have been a member of one of the many and competing sects of Judaism that then existed, an that sect could have espoused celibacy the reverse is equally plausible.For centuries, the traditional understanding has been that Judaism came before Christianity and that Christianity separated from Judaism some time after the destruction of the Second Temple in 70 CE.
Starting in the latter half of the 20th century, some scholars have begun to argue that the historical picture is more complicated. In the 1st century, many Jewish sects existed in competition with each other. These sects are detailed in the article on Second Temple Judaism. The sects which eventually became Rabbinic Judaism and Early Christianity were but two of these. Some scholars have begun to propose a model which envisions a twin birth of Christianity and Judaism rather than a separation of the former from the latter. For example, Robert Goldenberg (2002) asserts that it is increasingly accepted among scholars that "at the end of the 1st century CE there were not yet two separate religions called 'Judaism' and 'Christianity'."
