What event influenced the developments of Christian doctrines in the time of Ignatius of Antioch?

One event that influenced the developments of Christian doctrines in the time of Ignatius of Antioch was the persecution of Christians by the Roman Empire. Ignatius himself was a victim of this persecution, as he was arrested and eventually martyred for his faith. This persecution forced early Christians to clarify and articulate their beliefs in the face of opposition, leading to the development of more formalized doctrines and beliefs within the Christian community. Additionally, the need to defend and explain their faith to non-believers and critics also contributed to the development of Christian doctrines during this time.
