"'faith and love' . . . can be maintained only when docetism is rejected"

"Therefore adopt meekness and be renewed in faith, which is the flesh of the Lord, and in love, which is the blood of Jesus Christ."

ὑμεις οὖν τὴν πραϋπάθειαν ἀναλαβόντες ἀνακτήσασθε ἑαυτοὺς ἐν πίστει ὅ ἐστιν σὰρξ τοῦ κυρίου, καὶ ἐν ἀγάπῃ, ὅ ἐστιν αἷμα Ἰησοῦ Χριστοῦ.

     St. Ignatius, Trallians 8.1, as trans. Kirsopp Lake.  Cf. J. B. Lightfoot, The apostolic fathers:  Clement, Ignatius, and Polycarp 2.2 (1889), 171; Walter Bauer, Die Briefe des Ignatius von Antiochia und der Polykarpbrief, Handbuch zum Neuen Testament, Ergänzungsband 2 (Tübingen: Mohr (Siebeck), 1920), 236; William R. Schoedel & Helmut Koester, Ignatius of Antioch:  a commentary on the letters of Ignatius of Antioch, Hermeneia (Philadelphia:  Fortress Press, 1985), 149-150; etc. (I have not looked for any scholarship on this beyond (but not exhaustively!) the genre of the handy "commentary").  Schoedel & Koester, on the basis of a "study of the linking formula ('which is')":  "The basic concern seems to be the affirmation of the reality of the flesh (and hence of the suffering) of the historical Jesus. And this, in turn, is linked by Ignatius with the maintenance of true obedience and love (Sm. 6.2; cf. Tr. 2.1). For in Ignatius' mind 'faith and love' (cf. Sm. 6.1) can be maintained only when docetism is rejected."
     Cf. Romans 7.2-3, as trans. Lake, modifications mine:

[living (ζῶν)] I write to you[,] desiring [(ἐρῶν)] death.  My [desire (ἐρως)] has been crucified, and there is in me no fire of love [(πῦρ φιλόυλον)] for material things; but only water living and speaking in me [(ζῶν καὶ λαλοῦν, emended by Lightfoot (II.2 (1889), pp. 224-25) to ἁλλόμενον, from Jn 4:14 as interpolated into the long recension, welling up)] in me, and saying to me from within, 'Come to the Father.'  I have no pleasure in the food of corruption or in the delights of this life.  I desire [(θέλω)] the 'bread [(ἄρτον)] of God,' which is the flesh [(σὰρξ)] of Jesus Christ, who was 'of the seed of David,' and for drink I desire [(θέλω)] his blood [(αἷμα)], which is incorruptible love [(ἀγάπη ἄφθαρτος)].
