Intercultural contemporary societies pose challenges to modern citizens, as ancient Greco-Roman Empire posed to Jesus and his first followers many centuries ago. Globalization, migrations and colonialism, among others issues, bring about nowadays problems and possibilities similar to those faced by the first Christians. Jesus of Nazareth offered answers based in his religious experience, which produced a new representation of the God of Israel. His understanding of Yahve boosted him to reformulate basic principles of his own religion, such as purity, holiness or ethnicity. In addition, he created new intercultural spaces in which those excluded by the religious authorities could encounter God face to face.
