Christ’s Death and Resurrection
Ignatius of Antioch, Epistle to the Trallians 3.11
So flee from these evil offshoots that produce death-bringing fruit. If anyone tastes it, he dies on the spot. These people are not a planting of the Father. If they were, they would show themselves as branches of the cross, and their fruit would be imperishable. Through the cross, in his passion, he calls you, who are his members. A head cannot come to be without members, since God promises unity, and that unity is himself.
Greek
Φεύγετε οὖν τὰς κακὰς παραφυάδας τὰς γεννώσας καρπὸν θανατηφόρον, οὗ ἐὰν γεύσηταί τις, παῤ αὐτὰ ἀποθνήσκει. οὗτοι γὰρ οὔκ εἰσιν φυτεία πατρός, 2, εἰ γὰρ ἦσαν, ἐφαίνοντο ἂν κλάδοι τοῦ σταυροῦ, καὶ ἦν ἂν ὁ καρπὸς αὐτῶν ἄφθαρτος: δἰ οὗ ἐν τῷ πάθει αὐτοῦ προσκαλεῖταν ὑμᾶς ὄντας μέλη αὐτοῦ. οὐ δύναται οὖν κεφαλὴ χωρὶς γεννηθῆναι ἄνευ μελῶν, τοῦ θεοῦ ἕνωσιν ἐπαγγελλομένου, ὅ ἐστιν αὐτός.
