Summarized

The historical Jesus was Jewish, born into a Jewish family, a fact often overlooked by many Christians. Early Christian depictions of Jesus were not based on historical accuracy but on contemporary Roman, Ethiopian, or Chinese appearances, reflecting the artist's own culture. This practice continued, leading to controversial portrayals like the European-looking Jesus in The Passion of the Christ, where Jewish characters were stereotyped. This perpetuates a long and problematic history of antisemitism within Western Christianity.

Jesus was a marginal Jewish Galilean, likely a woodsmith, from Nazareth, a multi-ethnic region under Roman rule. It is important for Christians to distinguish between the historical Jesus (an academic construct based on literary criticism and history), the Jesus Christ of scripture (a figure depicted in the New Testament and interpreted within the Hebrew Bible), and the Christ of theology (a theological idea of God).

Challenges in reconstructing the historical Jesus include the lack of his own writings or artifacts, the absence of pre-Christian accounts of his movement, and anachronisms in early Christian accounts that reflect the authors' later contexts rather than Jesus's actual time. Our understanding of Jesus comes from Christian sources like Paul's letters, the canonical gospels, and other New Testament writings, all written for purposes other than historical narration. Jesus's teachings, originally in Aramaic, were passed down orally and then written in Greek, making direct access to his original words difficult.

The historical Jesus was a marginalized Jew from Nazareth, a disciple of John the Baptist, who began his own ministry and was crucified by the Romans under Pontius Pilate. Understanding "Jewish" in Jesus's day is crucial. Unlike modern Judaism, which largely descends from rabbinic Judaism (emerging after the destruction of the Second Temple), Jesus lived during the Second Temple period, when the temple was the central focus of Jewish worship. Christianity also grew out of Second Temple Judaism, evolving into an independent religion.

Jewish history and culture were influenced by Mesopotamian, Persian, Greek, and Roman empires. The Hasmonean kingdom, a short-lived independent Jewish state, saw the emergence of key Jewish sects: the Sadducees (hereditary nobility, literal interpretation of Torah, rejected afterlife concepts), Pharisees (scribal class, emphasized purity law, believed in an oral Torah and afterlife), and Essenes (ascetics, apocalyptic, believed in immortality and fatalism).

Jesus was in conflict with the Sadducees due to their wealth and his concern for the marginalized. While he shared some beliefs with the Essenes and Pharisees (like apocalypticism, resurrection, spirits, and angels), he also seemingly rejected asceticism (unlike the Essenes) and the Pharisaic doctrine of oral Torah. However, it's important to remember that these sects represented only a tiny elite, and the vast majority of Jews in Jesus's time didn't belong to any specific school. To understand the historical Jesus, he must be viewed within the context of his Jewish roots and the issues grappling with the diverse forms of Second Temple Judaism.
