Origins of Christianity

Early Christianity and Early Rabbinical Judaism were significantly influenced by Hellenistic religion and Hellenistic philosophy. Christianity in particular inherited many features of Greco-Roman paganism in its structure, its terminology, its cult and its theology. Titles such as Pontifex Maximus and Sol Invictus were taken directly from Roman religion. The influence of Neoplatonism on Christian theology is significant, visible for example in Augustine of Hippo's identification of God as summum bonum and of evil as privatio boni. Striking parallels between the New Testament account of Jesus and classical gods or demigods such as Bacchus, Bellerophon or Perseus were recognized by the Church Fathers and termed "demonic imitation" by Justin Martyr in the 2nd century.

Hellenistic culture had a profound impact on the customs and practices of Jews, both in the Land of Israel and in the Diaspora. The inroads into Judaism gave rise to Hellenistic Judaism in the Jewish diaspora which sought to establish a Hebraic-Jewish religious tradition within the culture and language of Hellenism.
