Greek Key Terms:
Context: Mark 7:14-23 is the climactic half of a single unified controversy story (Mark 7:1-23) in which the Pharisees and scribes confront Jesus over His disciples' failure to observe ceremonial handwashing ("the tradition of the elders"). Jesus replies first by exposing the traditions as human additions that nullify Scripture (vv. 6-13, citing Isa 29:13 and the Corban example). Then, summoning the crowd (v. 14), He issues a saying so programmatic Mark marks it with "Hear me, all of you, and understand" — formal revelation language: "There is nothing outside a person that by going into him can defile (koinōsai) him, but the things that come out of a person are what defile him" (v. 15). The disciples in private ask for the "parable" (v. 17), and Jesus explains: external foods enter the stomach and pass out — they cannot reach the heart where defilement lives. "Thus he declared all foods clean" (katharizōn panta ta brōmata, v. 19) — Mark's parenthetical editorial note making explicit the saying's dietary-code implication. Jesus then lists twelve heart-evils (vv. 21-22): six plural nouns of destructive action (sexual immoralities, thefts, murders, adulteries, covetings, wickednesses) followed by six singular vices (deceit, sensuality, envy, slander, arrogance, foolishness) — a comprehensive taxonomy covering sin against self, neighbor, and God. The capstone (v. 23): "All these evil things come from within, and they defile (koinoi) a person." The κοινόω verb, used seven times in 7:15-23, is the LXX/Jewish-Hellenistic technical term for ceremonial defilement (cf. Acts 10:14-15, 28; 21:28) — Jesus is not using general "make-dirty" language but the precise cultic vocabulary of Leviticus 11-15 and Numbers 19, now explicitly relocated from food-and-body to heart-and-action. The geographical context matters: Mark 7 occurs just before the Gentile-mission narrative (Mark 7:24-8:9 — the Syrophoenician woman, the Decapolis deaf-mute, the Gentile feeding of 4,000). Jesus's declaration that "all foods clean" is the theological precondition for the Gentile mission that occupies the rest of the chapter — a narrative arrangement Mark preserves and Luke will develop into Acts 10's full-scale dietary-code reversal.
Connections:
Connection Method(s): Contrast (primary — Fairbairn's reversal-not-escalation rule; Greidanus Method 7). Mark 7:14-23 does not amplify the dietary code but reverses it — the direction of defilement runs opposite to Leviticus 11's schema. Where Leviticus 11 taught that certain external foods defile those who eat them, Jesus teaches that external foods cannot defile the heart; defilement moves from inside out, not outside in. Mark's parenthetical "Thus he declared all foods clean" (v. 19) categorically abolishes the dietary distinctions Leviticus 11 and Deuteronomy 14 spent chapters establishing. This is not typological escalation (the NT antitype greater than the OT type); it is dietary-code supersession — the precise profile of Contrast in Greidanus's taxonomy. Fairbairn's methodological rule applies: when the NT reverses rather than amplifies the OT pattern, the connection is Contrast, not Typology. Hebrews 8:13 confirms: the first covenant is "obsolete." Typology contributes secondarily — the dietary code's purpose (teaching defilement's seriousness and holiness-through-separation) is fulfilled, not cancelled, in the heart-level moral cleansing Christ supplies; the code pointed beyond itself to an internal reality. Promise-Fulfillment also contributes — Ezekiel 36:26's new-heart promise presupposes exactly the diagnosis Jesus is giving (the problem is the heart, not the food).
Christological Connection: Mark 7:14-23 is the hinge on which the Ceremonial Uncleanness trajectory turns — the moment the dietary half of the Levitical code is authoritatively reversed by the Lord who gave it. Five Christological implications follow. First, Jesus's authority over the Torah is explicit. Only the Lawgiver can declare the Law's own distinctions superseded. Mark's parenthetical "Thus he declared all foods clean" — katharizōn panta ta brōmata, present participle modifying Jesus as the subject of the preceding saying — is a staggering christological claim. The same God who through Moses said "You shall not eat" of the unclean animals now says through the incarnate Son "all foods clean." Either Jesus is the Lord whose authority over Torah is the Torah's own authority, or He is a rogue blasphemer. Mark leaves no middle ground. Second, the relocation of defilement from outside to inside is not novelty but prophetic recovery. Psalm 51:10 had already located cleansing in the heart; Ezekiel 36:26 had already promised heart transplant; Jeremiah 31:33 had already prophesied law written on hearts. Jesus is not breaking with the OT; He is surfacing the OT's own self-interpretation against the Pharisees who had settled for surface observance. The defilement diagnosis — "from within, out of the heart of man, come evil thoughts…" — is what the Levitical code was trying to teach all along. Ceremonial external categories imaged real moral internal categories. Jesus declares the images fulfilled and the reality itself the operative concern. Third, the twelve-item heart-vice catalogue is a diagnosis no ceremony can treat. David's prayer in Psalm 51 made this discovery in a single autobiographical case; Mark 7 generalizes it. Murder, adultery, theft, covetousness, arrogance — these do not wash off with water, wait out until evening, or resolve with a heifer's ashes. Only a cleansing that reaches the heart can cleanse the heart. And only Christ supplies it. "The blood of Jesus his Son cleanses (katharizei) us from all sin" (1 John 1:7) — the same verb Mark used in "declared all foods clean" is now applied to Christ's own blood cleansing the conscience (Heb 9:14) that the dietary code could never reach. Fourth, the dietary-code reversal opens the Gentile mission. Mark 7:24 immediately sends Jesus to Tyre and Sidon, where He heals the daughter of a Syrophoenician Gentile woman — the narrative consequence of the dietary declaration. Acts 10:15 will extend the principle to people: "What God has made clean, do not call common (κοινόω — same verb as Mark 7:15, 18, 20, 23)." Peter's rooftop vision is the Acts fulfillment of Jesus's Mark 7 declaration; Paul's "nothing is unclean in itself" (Rom 14:14) is the Pauline application. The dietary boundary that separated Jew from Gentile is dissolved precisely because the defilement-diagnosis has been relocated — what defiles is not Gentile food but Jew-and-Gentile hearts equally, and Christ's blood cleanses equally. Fifth, Hebrews 8:13 finalizes the contrast. The first covenant is "obsolete," not fulfilled-by-escalation but categorically set aside in its ceremonial dimensions. The ceremonial code's purpose (teaching defilement's seriousness, holiness-through-separation) is preserved in new-covenant moral terms (the pattern continues by analogy, as the IP to 2 Cor 6:17 shows); the specific regulations are obsolete because Christ has made them so. This is the Fairbairn rule at work: where escalation obtains, read typology; where reversal obtains, read contrast. Mark 7:14-23 is the clearest reversal in the NT's treatment of the Mosaic ceremonial code, and for that reason it is the trajectory's hinge. The Levitical purity system was never the final word; it was teaching material pointing to a greater cleansing. When the greater cleansing arrives in the person of Christ — who cleanses hearts, not stomachs — the teaching material is released from its pedagogical duty and the trajectory moves forward, toward the consummate purity of Revelation 21-22 where nothing unclean ever enters, because in Christ nothing unclean remains.
