Library Ignatius of Antioch Epistles (Middle Recension)
Trallians, Chapter 10: The reality of Christ's passion
But if, as some that are without God, that is, the unbelieving, say, that He only seemed to suffer (they themselves only seeming to exist), then why am I in bonds? Why do I long to be exposed to the wild beasts? Do I therefore die in vain? Am I not then guilty of falsehood against [the cross of] the Lord?
