Orthodox Christianity Recommended Resources
Ignatius of Antioch, Letters
Composed while en route to his martyrdom in early second-century Rome, Ignatius’s letters offer our earliest window into post-apostolic Christianity. Ignatius’s passionate defense of church unity, his rich eucharistic theology, and his understanding of episcopal authority would profoundly shape Orthodox ecclesiology.
Melito of Sardis, On Pascha
This dramatic paschal homily, probably delivered around AD 170, exemplifies how early Christians read Scripture and celebrated their liturgical mysteries.
Irenaeus of Lyons, On the Apostolic Preaching
This catechetical work by one of the faith’s most important early theologians presents a comprehensive vision of salvation history centered on Christ. Writing against Gnostic interpretations that would separate the Old Testament from the New, Irenaeus demonstrates the profound unity of Scripture and tradition.
