Ignatius — Epistle to the Trallians 6
I therefore, yet not I, but the love of Jesus Christ, entreat you that you use Christian nourishment only, and abstain from herbage of a different kind; I mean heresy. For those [that are given to this] mix up Jesus Christ with their own poison, speaking things which are unworthy of credit, like those who administer a deadly drug in sweet wine, which he who is ignorant of does greedily take, with a fatal pleasure leading to his own death.
Greek
Παρακαλῶ οὖν ὑμᾶς, οὐκ ἐγώ, ἀλλ’ ἡ ἀγάπη Ἰησοῦ Χριστοῦ: μόνῃ τῇ χριστιανῇ τροφῇ χρῆσθε, ἀλλοτρίας δὲ βοτάνης ἀπέχεσθε, ἥτις ἐστὶν αἵρεσις: οἳ ἑαυτοῖς παρεμπλέκουσιν Ἰησοῦν Χριστὸν καταξιοπιστευόμενοι, ὥσπερ θανάσιμον φάρμακον διδόντες μετὰ οἰνομέλιτος, ὅπερ ὁ ἀγνοῶν ἡδέως λαμβάνει ἐν ἡδονῇ κακῇ τὸ ἀποθανεῖν.
