Christianity 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. Although the use of the term Christian is attested in the Acts of the Apostles (80–90 AD), the earliest recorded use of the term Christianity (Greek: Χριστιανισμός) is by Ignatius of Antioch about 107 AD, who is also associated with modification of the sabbath, promotion of the bishop, and critique of the Judaizers.
