Which religious belief most influenced the origins of christanity

The most influential religious belief that influenced the origins of Christianity is Judaism. Christianity emerged from the Jewish religious tradition, with Jesus and his early followers being Jewish. Many aspects of Christian theology and practice are rooted in Jewish beliefs, scriptures, and traditions, including the concept of a single, monotheistic God, the importance of ethical behavior, and the belief in a messianic figure who would bring salvation to humanity. Jesus himself was seen as the fulfillment of Jewish prophecies and teachings, and the early Christian community grew out of the Jewish communities in ancient Israel.
