Ignatius of Antioch (; Ancient Greek: Ἰγνάτιος Ἀντιοχείας, romanized: Ignátios Antiokheías; died c. 108/140), also known as Ignatius Theophorus (Ἰγνάτιος ὁ Θεοφόρος, Ignátios ho Theophóros, 'the God-bearing'), was an early Christian writer and Patriarch of Antioch. While en route to Rome, where he met his martyrdom, Ignatius wrote a series of letters. This correspondence forms a central part of a later collection of works by the Apostolic Fathers. He is considered one of the three most important of these, together with Clement of Rome and Polycarp. His letters also serve as an example of early Christian theology, and address important topics including ecclesiology, the sacraments, and the role of bishops.
