Christianity began as a movement within Second Temple Judaism, but the two religions gradually diverged over the first few centuries of the Christian Era, and the Christian movement perceived itself as distinct from the Jews by the fourth century.[2] Historians continue to debate the dating of Christianity's emergence as a discrete religion apart from Judaism.[3]Philip S. Alexander characterizes the question of when Christianity and Judaism parted company and went their separate ways (often termed the parting of the ways) as "one of those deceptively simple questions which should be approached with great care".[4] According to historian Shaye J. D. Cohen, "the separation of Christianity from Judaism was a process, not an event", in which the church became "more and more gentile, and less and less Jewish".[5] Conversely, various historical events have been proposed as definitive points of separation, including the Council of Jerusalem and the First Council of Nicaea.
Historiography of the split is complicated by a number of factors, including a diverse and syncretic range of religious thought and practice within Early Christianity and early Rabbinic Judaism (both of which were far less orthodox and theologically homogeneous in the first centuries of the Christian Era than they are today) and the coexistence of and interaction between Judaism, Jewish Christianity, and Gentile Christianity over a period of centuries at the beginning of Early Christianity.[6] Some scholars have found evidence of continuous interactions between Jewish-Christian and Rabbinic movements from the mid-to late second century CE to the fourth century CE.[7][8] The first centuries of belief in Jesus have been described by historians as characterized by religious creativity and "chaos".[9][10]
The two religions eventually established and distinguished their respective norms and doctrines, notably by increasingly diverging on key issues such as the status of "purity laws" and the validity of Judeo-Christianmessianic beliefs.[citation needed]

^Cohen 1987, p. 228"The separation of Christianity from Judaism was a process, not an event. The essential part of this process was that the church was becoming more and more gentile, and less and less Jewish, but the separation manifested itself in different ways in each local community where Jews and Christians dwelt together. In some places, the Jews expelled the Christians; in other, the Christians left of their own accord." sfn error: no target: CITEREFCohen1987 (help)
