Christianity in the ante-Nicene periodChristianity in the ante-Nicene period was the time in Christian history up to the First Council of Nicaea. This article covers the period following the Apostolic Age of the first century, c. 100 AD, to Nicaea in 325 AD. The second and third centuries saw a sharp divorce of Christianity from its early roots. There was an explicit rejection of then-modern Judaism and Jewish culture by the end of the second century, with a growing body of adversus Judaeos literature.

Christianity in the 5th centuryIn the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God.
Christianity in the 1st centuryChristianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (27–29 AD) to the death of the last of the Twelve Apostles (100) and is thus also known as the Apostolic Age.
