This timeline meticulously chronicles the gradual yet decisive separation of Christianity from its Jewish origins, detailing pivotal events and theological developments up to 400 CE. Beginning with the crucifixion and resurrection of Jesus, the narrative highlights critical moments like Paul's mission to the Gentiles and the Council of Jerusalem, which fundamentally established a non-Jewish path to Christian identity. The destruction of the Second Temple in 70 CE profoundly impacted both faiths, forcing Judaism to reform while solidifying Christianity's distinct trajectory. Later, the completion of the New Testament canon and pronouncements by influential Church Fathers like Justin Martyr and Tertullian further articulated Christian doctrines as separate from, and often superseding, Jewish law. Finally, imperial decrees such as the Edict of Milan and the Edict of Thessalonica elevated Christianity to the official religion of the Roman Empire, marking its complete political and theological independence from Judaism
