Also J 6:51–56 urges that one must eat the flesh (and drink the blood) of the Human One or Son of Man (Just., A I, 66, 2; s. TPhilips, Die Verheissung der hl. Eucharistie nach Joh. 1922; Bultmann ad loc.; AWikenhauser ’48, 105f).—His anti-Docetic position also leads Ign. to use the concept ‘flesh (and blood) of Christ’ in other contexts as well ITr 8:1; IPhld 5:1.—For Mt 16:17; Gal 1:16; Eph 6:12; and 1 Cor 15:50 s. 3a.

    α. In Paul’s thought esp., all parts of the body constitute a totality known as ς. or flesh, which is dominated by sin to such a degree that wherever flesh is, all forms of sin are likew. present, and no good thing can live in the σάρξ Ro 7:18 (cp. Philo, Gig. 29 αἴτιον δὲ τῆς ἀνεπιστημοσύνης μέγιστον ἡ σὰρξ καὶ ἡ πρὸς σάρκα οἰκείωσις; Sextus 317 ἀγαθὸν ἐν σαρκὶ μὴ ἐπιζήτει. The OT lays no stress on a necessary relationship betw. flesh as a substance, and sin. But for Epicurus the σάρξ is the bearer of sinful feelings and desires as well as the means of sensual enjoyment: Ep. in Plut., Mor. 135c; 1087bf; 1089e; 1096c αἱ τῆς σαρκὸς ἐπιθυμίαι. Also Diog.

Ps 142:2 πᾶς ζῶν); 1 Cor 1:29 (μή); Gal 2:16.—Though ς. in the foll. passages refers to body in its physical aspect, it cannot be divorced from its conjunction with αἷμα, and the unit σὰρξ καὶ αἷμα (cp. Sir 17:31; TestAbr B 13 p. 117, 26 [Stone p. 82]; Philo, Quis Div. Rer. Her. 57; Just., D. 135, 6) refers to a human being in contrast to God and other transcendent beings Mt 16:17; Gal 1:16; Eph 6:12 (here vice versa, αἷ. καὶ ς.). τὰ παιδία κεκοινώνηκεν αἵματος καὶ σαρκός the children share mortal nature Hb 2:14, but with suggestion of its frailty, as indicated by the context with its ref. to death.

The context of 2 Cor 11:18 includes ancestry as a reason for boasting, but ς. in this pass. applies as well to other aspects of Paul’s career and therefore belongs more properly in 5.

    catalytic converter
    Catalytic converters are designed to clean up the exhaust fumes from petrol-driven vehicles, which are otherwise the major threat to air quality standards in congested urban streets and on motorways. Converters remove carbon monoxide, the unburned hydrocarbons and the oxides of nitrogen. These compounds are damaging to human health and the environment in a variety of ways. The converter is attached to the vehicle' s exhaust near the engine. Exhaust gases pass through the cellular ceramic substrate, a honeycomb-like filter. While compact, the intricate honeycomb structure provides a surface area of 23.000 square metres. This is coated with a thin layer of platinum, palladium and rhodium metals, which act as catalysts that simulate a reaction to changes in the chemical composition of the gases. Platinum and palladium convert hydrocarbons and carbon monoxide into carbon dioxide and water vapour. Rhodium changes nitrogen oxides and hydrocarbons into nitrogen and water, which are harmless.
