Ignatius to the Trallians

I exhort you therefore-yet not I, but the love of Jesus Christ-take ye only Christian food, and abstain from strange herbage, which is heresy:

Παρακαλῶ οὖν ὑμᾶς, οὐκ ἐγώ, ἀλλ̓ ἡ ἀγάπη Ἰησοῦ Χριστοῦ: μόνῃ τῇ χριστιανῇ τροφῇ χρῆσθε, ἀλλοτρίας δὲ βοτάνης ἀπέχεσθε, ἥτις ἐστὶν αἵρεσις:

for these men do even mingle poison with Jesus Christ, imposing upon others by a show of honesty, like persons administering a deadly drug with honeyed wine, so that one who knoweth it not, fearing nothing, drinketh in death with a baneful delight.
