To say that Jesus didn't found Christianity would immediately anger many people. However, upon closer inspection of the phrase, it is difficult to say otherwise. The earliest book that came to be in the New Testament was written decades after Jesus' death and the Christian doctrines and creeds were created centuries later. The reality is that Christianity didn't exist until after Jesus' time and therefore couldn't have been created by him. After Jesus' departure, many people took to writing down what had happened and what it meant. The first problems for Christianity arose when these writings turned out to be very different from each other. In fact, the practices and beliefs of people who called themselves Christians during the first three centuries were so varied that the differences between modern Christian sects pale in comparison.
During the second half of the second century, with the growing number of prophetic and perceived heretical movements among Christians, there was great need for a fixed canon. Christian groups such as the Marcionites, the Ebionites, the Gnostics, and the proto-orthodox all insisted that they correctly upheld the teachings of Jesus and were all in competition to become the rightful version that would eventually be adopted by the Roman Empire. The proto-orthodox, named as such because of its eventual victory, was ultimately endorsed by Constantine as the primary religion of the Roman Empire. As the proto-orthodox text “developed into the dominant religious, political, economic, social, and cultural institution of the West”, the other defeated texts were labeled heretical and were “rejected, scorned, maligned, attacked, burned, [and] all but forgotten”.
