Polycarp to the Philippians

For every one who shall not confess that Jesus Christ is come in the flesh, is antichrist: and whosoever shall not confess the testimony of the Cross, is of the devil; and whosoever shall pervert the oracles of the Lord to his own lusts and say that there is neither resurrection nor judgment, that man is the firstborn of Satan.

Πᾶς γὰρ ὃς ἂν μὴ ὁμολογῇ Ἰησοῦν Χριστὸν ἐν σαρκὶ ἐληλυθέναι, ἀντιχριστός ἐστιν: καὶ ὃς ἂν μὴ ὁμολογῇ τὸ μαρτύριον τοῦ σταυροῦ, ἐκ τοῦ διαβόλου ἐστίν: καὶ ὃς ἂν μεθοδεύῃ τὰ λόγια τοῦ κυρίου πρὸς τὰς ἰδίας ἐπιθυμίας καὶ λέγῃ μήτε ἀνάστασιν μήτε κρίσιν, οὗτος πρωτότοκος ἐστι τοῦ σατανᾶ.
