Final answer:
The life of Jesus is well-documented in the New Testament, particularly the Gospels, and while his teachings included the notion of a messianic role, the interpretation of this role caused divisions among Jews and early Christians.
Step-by-step explanation:
The life of Jesus spanned from his birth in about 4 B.C. to his crucifixion and subsequent events of resurrection and ascension in A.D. 30. His life included three years of authoritative teaching and working of miracles and was marked by the hostility of the Jewish religious establishment. The major source of information on the life of Jesus is the four Gospels: Matthew, Mark, Luke, and John, which are accounts composed after his death and found in the New Testament. The concept that Jesus was the messiah is a traditional part of Jewish theology; however, not all Jews recognized Jesus as such, particularly because they anticipated a messiah who would liberate them from Roman rule. This expectation was not met in the social-political sense, given Judea remained under Roman control after Jesus's death. Nonetheless, early Christians, guided by Paul's teachings, believed that Jesus's role as the messiah was spiritual, providing a path for salvation and atonement from sin.
