Context: Hebrews 12:22-24 is the climactic positive pole of the Sinai/Zion contrast the author constructs in 12:18-24. Verses 18-21 describe what believers "have not come to" — the terrifying palpable mountain of Sinai, with fire, darkness, storm, trumpet blast, and Moses trembling. Then verse 22 inaugurates the positive pole with a sharp "but" (ἀλλά) and the perfect-tense verb προσεληλύθατε ("you have come"): a completed-action-with-abiding-result declaration that Christian believers have already arrived at Mount Zion, the heavenly Jerusalem. The sevenfold catalog of arrival follows — Mount Zion, city of the living God, heavenly Jerusalem, myriads of angels, assembly of the firstborn enrolled in heaven, God the Judge of all, spirits of the righteous made perfect — and climaxes in the two distinctly christological items: "Jesus the mediator of a new covenant, and the sprinkled blood that speaks a better word than the blood of Abel" (12:24). The author's rhetorical goal within Hebrews is to ground the exhortation of chapters 12-13 (endure discipline, pursue holiness, do not refuse Him who speaks) in the ontological fact that readers have already been admitted to the eschatological city. This is the inaugurated pole of the already/not-yet structure that governs the whole Sarah-heavenly-mother trajectory.

Intertextual Connection: Hebrews 12:22-24 ← Isaiah 2:2-3; Hebrews 12:24 ← Genesis 4:10
Christological Connection: Hebrews 12:22-24's theological meaning is that the cosmic gathering promised to the eschatological Zion is not an exclusively future hope — it is an already-present reality to which believers have come (perfect tense) through Christ. The sevenfold catalog describes a single arrival at a single destination: Mount Zion, which is the heavenly Jerusalem, which is the city of the living God, which is the festal assembly of angels and redeemed saints, which is presided over by God the Judge and centered on Jesus the mediator. The author grounds the arrival in Jesus' two roles: mediator (μεσίτης) of a new covenant, and provider of sprinkled blood that speaks atoningly. These two items are not parallel decorations; they are the mechanism by which the arrival is possible.
Within the Sarah-trajectory, this text functions as the already-pole of the heavenly-mother eschatology. Paul's Gal 4:26 declaration that "the Jerusalem above… is our mother" raises the question: when and how do Sarah's heavenly-mother-children actually arrive at their mother's city? Hebrews answers: they have already arrived through Christ. The barren-matriarch paradigm that Isaiah 51-54 transposed onto Zion and Paul applied allegorically to the new covenant reaches its inaugurated fulfillment in the moment of Christ's cross-and-resurrection, by which believers are constituted "the firstborn enrolled in heaven" (12:23) and given access to "the city of the living God" (12:22). The escalation from the Sinai covenant (which bears children for slavery, Gal 4:24) to the new covenant is accomplished precisely by Jesus' mediation and sprinkled blood (12:24). What the Levitical system could not finally achieve — the people's genuine arrival in the presence of the living God — Christ has achieved through a better mediation and better blood.
The contrast with Sinai (12:18-21) is structurally significant for the Sarah-trajectory. Paul's Gal 4:21-31 argument maps Hagar ↔ Mount Sinai ↔ present Jerusalem against Sarah ↔ new covenant ↔ Jerusalem above. Hebrews 12:18-24 performs the identical mapping on different ground: Sinai (terrifying, untouchable, Mosaic, bearing-for-slavery) versus Zion (joyful, accessible, Jesus-mediated, bearing-the-firstborn-enrolled-in-heaven). The two passages are companion articulations of the same covenantal-ecclesial theology. Paul's allegorical reading in Galatians and Hebrews's contrastive reading in Hebrews 12 converge on the single truth that the new covenant people have their mother and their city in heaven, and have already been admitted there through the mediation of Jesus.
The already/not-yet staging is explicit in the Hebrews text itself. Already: προσεληλύθατε (perfect tense) — believers have come to Mount Zion. This is not aspirational language but a completed-action declaration. The new Jerusalem is already the Christian's home-city in an ontologically real sense, even while the visible world continues under the shaking of 12:26-27. Not yet: the consummate descent of the new Jerusalem as bride awaits Christ's return (Revelation 21:2), at which point the already-present heavenly city is revealed visibly and cosmically. Hebrews and Revelation are not in tension; they are the two poles of the already/not-yet structure of the same eschatological reality. Christ's sprinkled blood — the new-covenant mediation that grants already-arrival — is also the ground of the not-yet consummation. The barren-mother's children, already enrolled in heaven in the already, will be gathered visibly at the descent in the not-yet.
Connection Method(s): Promise-Fulfillment (primary) — Hebrews reads the OT's Zion-eschatology (Isa 2, 25, 60-62; Ps 48; Zech 14) and Jeremiah's new-covenant promise as reaching their inaugurated fulfillment at the cross. The verbal commitments of OT prophecy — nations streaming to Zion, covenant renewed, sins remembered no more — are cashed out in Jesus' mediation and sprinkled blood. Also Redemptive-Historical Progression — the text is a canonical hinge, deliberately positioned against Sinai (12:18-21) to mark the new-covenant stage in the redemptive-historical arc. The "already come to Mount Zion" declaration is a redemptive-historical status claim. Also Contrast — the Sinai/Zion opposition is explicit and structural (12:18-24), and runs parallel to the Hagar/Sarah opposition at Gal 4:21-31. The passage operates substantially through contrast: what believers have not come to (the old covenant's terrifying inaccessibility) versus what they have come to (the new covenant's festal welcome). Also Longitudinal Theme — this is a major node in the Temple-and-Presence / New Jerusalem / Heavenly Mother trajectories, gathering threads from Eden (presence) through Sinai (approach denied) through the earthly temple (mediated access) to Zion-above (perfected access). Typology is not the primary lens (anti-default check): the passage operates through covenantal-eschatological fulfillment rather than type-antitype structural correspondence. Sinai and Zion are not a type-antitype pair in Fairbairn's strict sense but two covenantal economies under contrast; the "heavenly Jerusalem" is not an escalated antitype of an earthly Jerusalem-type but the eschatological reality of which any earthly city is at best a provisional signpost. This matches TT 139's classification of the Sarah trajectory as Promise-Fulfillment + Analogy + Longitudinal Theme + Contrast, without claiming Typology.
