Ignatius of Antioch, Epistle to the Magnesians 8
There is one God. He has made himself known through Jesus Christ, his Son, who is his Word, come forth from silence, and who in every way pleased the One who sent him (John 8:29).
Greek
εἶς θεός ἐστιν, ὁ φανερώσας ἑαυτὸν διὰ Ἰησοῦ Χριστοῦ τοῦ υἱοῦ αὐτοῦ, ὅς ἐστιν αὐτοῦ λόγος ἁπὸ σιγῆς προελθών, ὃς κατὰ πάντα εὐηρέστησεν τῷ πέμψαντι αὐτόν.
