Library Ignatius of Antioch Epistles (Middle Recension)
Ephesians, Chapter 17: Beware of false doctrines
For this end did the Lord allow the ointment to be poured upon His head, John 12:7 that He might breathe immortality into His Church. Be not anointed with the bad odour of the doctrine of the prince of this world; let him not lead you away captive from the life which is set before you. And why are we not all prudent, since we have received the knowledge of God, which is Jesus Christ? Why do we foolishly perish, not recognising the gift which the Lord has of a truth sent to us?
