01The Outcomes — 5 scenarios, priced by the research

Managed Southern Pivot (modal): a demographically African Church held together by de-escalation38–48%

By 2050 Catholicism remains the world's largest institution and a living tradition, but its center of gravity has moved south: ~1-in-3 Catholics African, Africa past Europe in share and practice, African/Asian clergy backfilling a sacramentally-rationed West propped on the rolls by immigration. No mass-capturing schism. Leo XIV and a likely continuity successor generalize the Querida Amazonia template: receive consultations, decline ruptures, govern by personnel not constitutions. The German Synodal Conference is reined to consultative-only; the China accord limps on; the Latin Mass governed by quiet indult. This ABSORBS two textures the council could not distinguish on 2050 observables: a confident Africa-led conservative orthodoxy (irreformable spine unchanged), and a smaller-but-committed Western remnant if the 2025 plateau holds. Ordination/marriage doctrine formally unchanged.

How this number was derived
Decomposition x continuity floor. Schism leg RE-ANCHORED (Kerr pre-1520 'intact >0.90' DEFEATED by 3 members as wrong-question / mis-coding schism as continuity) to the shared post-1789 count: 2 lasting schisms in 9 windows -> P(no rupture/window) ~0.78. x P(no definitive-doctrine reversal) ~0.85 (Manifold female-priests ~21% YES -> ~0.79 NO) x P(Southern pivot proceeds | already-born cohorts) ~0.92 ~= 0.61 for 'destination holds without rupture.' This bucket SPLITS across managed-continuity (incl. Southern-orthodoxy + West-floor texture, folded in) vs hollowing/fracture/reform. Held 38-48%: the 6-joint deflation to ~30% defeated for treating correlated joints as independent; the 50-62% top trimmed for double-pricing an over-broad 'intact' leg. GMO-of-odds of the five members' continuity-family midpoints ~0.52.

Drivers

  • Driver 1 demographic engine (dominant through ~2040): African +3.31%/yr, share 20.3% past Europe 20.1%; the adults of 2045 already born
  • Papal authority as centripetal COMMON CAUSE (not independent coin-flips): a calm pontificate co-produces no-schism + no-reversal + managed polarization; church-tax money + Roman legitimacy + anti-Pentecostal alliance favor communion
  • Driver 3 priest-shortage stack: Western consolidation + imported clergy absorb the shortage; African seminarians the only growing pool
  • Drivers 5/7: synodality institutionalizes disagreement short of schism; immigration buffers Western decline; Southern agenda-setting is a TEXTURE here, not a separate destination

Signals to watch

  • Leo XIV's first creating consistory (none as of mid-2026): deepen vs rebalance the Global-South tilt
  • Roman recognitio on the German Synodal Conference ruled consultative-only AND accepted
  • ASE data: African share widening past Europe; global total near/above 1.4bn; African seminary ENTRIES still rising
  • No reversal of Ordinatio Sacerdotalis; Manifold female-priests-by-2050 staying ~21%; no signature divisive Leo act
Horizon · through ~2050 (structural horizon; recognitio outcome and first consistory visible by ~2028)
Hollowed Crown: the Southern count holds, the living tradition thins (the LatAm echo, measured late)18–30%

The center-of-gravity shift happens on the books exactly as projected and is partly hollowed underneath. The Vatican count still reads ~1.4bn+ and Africa overtakes Europe by baptized membership (a near-irreversible status Rome counts), but practice, per-capita vocations, and retention erode on both ends: the 2025 Western plateau proves a way-station as cohort replacement resumes, and African/Asian Catholicism begins following the Latin American practice-decline-despite-high-fertility curve, losing the marginal convert to Pentecostal/charismatic and African-Independent-Church competition (Pew Jan 2026: LatAm share down 9-19 pts across six countries; Brazil/Chile to 46%). The 2050 Church is 'demographically African' in the yearbook and contested on the ground — the corpus's single largest acknowledged uncertainty (Open Q1).

How this number was derived
Reference-class transfer (LatAm -> Africa), range WIDENED to preserve the council's largest surviving disagreement, not split it. Two members (contrarian 28-38%, discontinuity 25-35%) vs three (base-rate 13-20%, driver 13-21%, actor 12-18%). Cross-exam TRIMMED the top via Open Q3 (the secularization half is slow to reach a still-Christianizing Africa): 30-40% defeated as conflating 'on the curve' (~0.35) with 'dominant by 2050' (~0.15). It did NOT resolve low: African TFR grows the count while practice falls (a mechanism the 6/6 share-loss class doesn't price). Decompose: P(Pentecostal-portable competition material by 2050) ~0.55 x P(erosion | competition) ~0.70 x P(material not incipient) ~0.55-0.65 ~= 0.21-0.25. The 18-30% band spans both grounded poles; midpoint ~24% matches GMO-of-odds (~0.21) nudged up for the count-vs-practice mechanism.

Drivers

  • Driver 1's transmission caveat: a large BAPTIZED base is not a large PRACTICING base (Vatican counts baptisms in Africa)
  • Pentecostal/charismatic surge (CSGC >1bn by 2050) taking the marginal Global-South convert; weak density (~5,101 Catholics/priest in Africa)
  • Driver 2 cohort-replacement secularization resuming past the 2025 Western plateau; baptized-vs-practicing gap widening
  • Open Q3 brake: LatAm loss ran to NONES as much as Pentecostals outside Brazil; only the Pentecostal-capture HALF imports fast to a still-Christianizing Africa

Signals to watch

  • First rigorous African Catholic PRACTICE survey (not baptismal): attendance well below baptismal share -> confirms; and WHETHER losses run to Pentecostals (fast) or nones (slow)
  • Pew/CSGC African data replicating the LatAm pattern (>=9-pt drop); Pentecostal/AIC share crossing Catholic in a second country
  • African seminary ENTRIES flattening or falling
  • Pew/CARA: US/European plateau breaking downward post-2027; US Latino Catholic share's 67%->43% slide continuing
Horizon · through ~2050; the African-practice signal resolves slowest and may show only its EARLY phase by 2050 (a 25-40 yr process)
Fractious Transition: regional de facto schism short of formal rupture14–22%

Same demographic destination, disorderly path. Polarization (Driver 5), amplified by the Catholic internet (Driver 6) and a parallel donor-media infrastructure, hardens past containment. The modal form is a DE FACTO partial rupture: a German national church running ahead with a binding lay-bishop Synodal Conference Rome cannot rein in; and/or the SSPX's 1 July 2026 Econe consecrations consolidating a parallel hierarchy rather than re-reconciling; and/or a US diocese breaking communion; and/or — as the center shifts south — an African-conservative bloc breaking from a future progressive Rome (the axis rotates). The center keeps the majority, but Rome's writ is regionally ignored and the fiction of one governance ends. Live flashpoints (Econe, the German recognitio) cluster in 2026-2028.

How this number was derived
Reference-class + market triangulation, broadened to de-facto rupture and TRIMMED for mass-capture. Class = durable fractures after a doctrinal hinge: Vatican I->Old Catholics 1870; Vatican II->SSPX 1988. ~2 of 2 produced a break, but BOTH stayed marginal — ~0 of ~4 hinges captured a national episcopate. So P(some fresh break) is high; P(it captures real mass) is rare (~0.10-0.12 base). The de-facto threshold (a national church running its own discipline) is an EASIER bar, raising at-least-one; multi-conclave exposure adds. Market checks (thin Manifold): US-diocese-break-before-2030 ~19%; German-women-by-2028 ~18%; SSPX-excomm-2026 ~89% (penalty, NOT durable schism). Blending the ~19% proxy (horizon-scaled), the ~22%/horizon base rate, the de-facto uplift, and the centripetal/absorption discount -> 14-22%. The FORMAL version sits ~8-12%; the de-facto regional version carries the weight.

Drivers

  • Driver 5 polarization funded/broadcast by a parallel infrastructure (EWTN/Napa vs progressive; German DBK/ZdK Synodal Conference, 54/81 non-bishop seats)
  • Driver 6 'Catholic internet' magnifying intense factions beyond footprint (TLM ~2% but discourse-dominant)
  • Going-concern flashpoints: SSPX Econe consecrations (1 July 2026; Fernandez's 13 May 2026 'schismatic act' warning) — a 1988 replay; German statutes awaiting recognitio
  • Driver 1 axis-rotation: a confident-orthodoxy Southern pope is the profile that can CAUSE a Western/German de-facto break; Fiducia/SECAM override as precedent

Signals to watch

  • The recognitio decision and whether Woelki-type bishops or the ZdK reject it; the Conference proceeding against a restrictive ruling
  • SSPX Econe consecrations proceeding AND a parallel hierarchy consolidating (vs regularization)
  • Any US/German diocese formally breaking communion (Manifold ~19% by 2030); a second continental override of a Roman document
  • Cardinal-level declarations of a pope's illegitimacy; a diocese dropping the papal name from the Canon
Horizon · through ~2050; flashpoints (Econe, German recognitio) visible 2026-2028, confirmed by early-to-mid 2030s
Forced Adaptation: the priest shortage cracks the celibacy/diaconate discipline8–14%

Against the base-rate grain, the Church makes a discontinuous opening on the MOVABLE margin: by the late 2030s, as the Western imported-clergy buffer drains (visa tightening; a retirement bolus) and Eucharistic famine spreads, Rome opens a REGIONAL married-priesthood path (viri probati made general, breaking the Querida Amazonia template) and/or restores a women's diaconate — the door the Dec 2025 commission left ajar before Study Group 5's March 2026 'new ministries' soft closure. This is DISCIPLINE, not doctrine (23 Eastern Catholic churches ordain married men; Cum data fuerit rescinded June 2014; ex-Anglican Ordinariates), so the barrier is prudential. Women's PRIESTHOOD stays closed (doctrine-locked by Ordinatio Sacerdotalis). Most realizations are incremental (a quiet indult absorbed into Managed Pivot); this is the SCENARIO-DEFINING general version.

How this number was derived
Market-anchor + base-rate ceiling, sized to the SCENARIO-DEFINING general opening. Priesthood near-excluded (OS infallible note) ~0.05-0.10 despite Manifold female-priests ~21%. Reachable legs are DISCIPLINE, pricing higher: P(regional married-priest opening by 2050) ~0.18 + P(restored women's diaconate) ~0.20, near-independent -> P(at least one) ~1-(0.82x0.80) ~0.34. But most is INCREMENTAL (a quiet indult absorbed into Managed Pivot); discount for Rome's Querida-Amazonia decline-rupture reflex and the Southern-conservative drag (x ~0.30-0.45) -> ~0.09-0.13. Range 8-14%. This decomposition survived cross-examination unrefuted (contrarian: 'no rival landed a hit'); the only move was trimming the discontinuous top vs absorbing incremental versions into the modal. GMO-of-odds of members' reform midpoints ~0.11.

Drivers

  • Driver 3 as forcing function: US ~1-in-4 priests foreign-born plus a flagged visa 'serious new crisis'; the retirement bolus; sacramental rationing
  • Celibacy is changeable DISCIPLINE (Eastern Catholic married priests; Cum data fuerit rescinded 2014) — a lever Rome can pull
  • Women's-diaconate 'remains open' (Synod 2024) but redirected to 'new ministries' (Study Group 5, March 2026) = soft, not hard, closure
  • A reformist conclave + Global-South pastoral need (Amazon) as the least-polarizing first venue; offset by the Southern-conservative College as the center shifts south

Signals to watch

  • Any regional viri-probati / married-priest indult (Amazon, Pacific, parts of Africa) — the clearest single trigger
  • A papal ruling admitting women to the diaconate vs soft-closing via 'new ministries'
  • A diocese/conference formally petitioning Rome for married priests; Manifold celibacy/diaconate proxies above ~25%
  • A reformist pope elected before the Southern-conservative majority consolidates (watch Leo's age/health and cardinal-creations)
Horizon · through ~2050; a regional opening plausible late 2030s, most actionable in the next 1-2 conclaves
Discontinuity Tail: geopolitical, financial, or governance rupture4–8%

A residual of low-base-rate, high-variance discontinuities no smooth demographic curve predicts: the Vatican-China accord collapses and re-divides the ~10-12m Chinese Catholics if Beijing's unilateral appointments break the secret provisional deal; a financial rupture (the unaddressed 1.5bn-euro+ pension liability, a fresh post-Becciu corruption blow, the abuse-litigation wave maturing in Global-South tort regimes); a sharply discontinuous conclave moving against the College's grain; or an ecumenical breakthrough (the 2025 Nicaea-1700 Leo-Bartholomew 'full communion' rhetoric converting to substance). Driver 8 is the forecast's main fat-tail source: it rarely moves the aggregate count but can produce large, discrete, hard-to-forecast outcomes. Conservative succession variance and de-facto-fracture mass are booked elsewhere, keeping this tail genuinely residual.

How this number was derived
Disjunction of low-probability tails, each market/base-rate-anchored, HELD at 4-8%. The discontinuity member's standalone Succession Shock at 12-20% was DEFEATED as double-counting: a conservative-Southern pope reasserting is spine-continuity (S1), and a rupture-conclave feeds Fractious Transition (S3) — so most succession variance is re-homed, and P(sharp REFORM departure against a Francis-built ~48%-Global-South College | new pope) is rarer than the claimed ~0.30. Remaining disjuncts: China-accord rupture over 24 yrs given a deal Beijing has already breached ~a few %; a Vatican financial rupture ~a few %; Catholic-Orthodox FULL communion by 2050 (Manifold reconciliation ~17%, full communion lower) ~low single digits. Net of succession variance in S1 and de-facto fracture in S3, the genuinely-novel residual over 25 yrs ~= 4-8%. Acknowledged, not modeled.

Drivers

  • Driver 8 geopolitics: the China accord (renewed 4 yrs Oct 2024, secret text, Beijing already breaching) as the single-event-risk driver
  • Driver 4 abuse-litigation/finance tail: pension bomb unaddressed, insurer retreat, the reckoning deferred to (not avoided in) the Global South
  • Pontificate contingency: a reform-against-the-College swing (vs a conservative-Southern swing, which is spine-continuity in Managed Pivot)
  • Ecumenical momentum (2025 Nicaea-1700 Leo-Bartholomew pledge) as a low-odds UPSIDE discontinuity

Signals to watch

  • China accord non-renewal/collapse or Beijing installing bishops Rome rejects en masse
  • A Vatican financial event (pension default risk; a new corruption indictment); first major abuse judgments outside the West
  • Leo XIV health/continuity (Manifold gone-before-2030 ~19%; still pope 2038 ~29%); a contentious next conclave
  • Concrete Orthodox steps (common Easter date, a primacy formula) beyond rhetoric
