These two sources are almost opposite species of missions document, and that contrast is itself the most useful thing to see. Also a look at a third source in the DMM approach.
What each one is measuring
Joshua Project’s JP+ report is a quantitative intelligence product. Its unit of analysis is the people group, and its currency is countable things: 2 groups added and 1 removed to the people-group list, a net gain of 1, and 43 added and 17 removed across countries for a net gain of 26. Status changes are tracked as discrete events — five groups moving from unreached to not unreached, the Frontier count rising by four newly classified groups — and even language access is tallied: 498 language resources added and 56 new scripture translations, comprising 7 full Bibles, 21 New Testaments, and 28 Portions. The whole enterprise is built to answer “how many, where, and how confident are we.”
The Basque JOY material has no comparable metric anywhere. It explicitly rejects the JP-style unit: “the framework refuses to measure success by the metrics most ministry frameworks use — attendance, conversions, church plants, organizational growth, budget expansion.” Its evidence isn’t a count, it’s a pattern of qualitative signals — things like whether “at least one Basque participant has felt free enough to tell the catalyst they misread something,” or whether a rhythm “would survive the catalyst’s absence.” Progress is read through convergence of indicators, not tallies.
Methods for establishing confidence
Here the two are structurally closer than they first appear, even though the vocabulary differs completely. JP’s Phase of Engagement system explicitly runs on triangulation: phase assignment comes from organizational bulk submissions, individual field reports, and GAPP activity data, with confidence rising when multiple inputs converge on the same phase rather than accepting the single highest reported number.
Basque JOY’s “threshold discernment” is doing the same epistemic work by a different route: it’s built on convergence between two vantage points — the Basque insider’s terrain-knowledge and the outside catalyst’s cross-cultural pattern recognition — tested in a recurring “debrief” where what each has noticed is compared and held together, explicitly described as “two sets of eyes trained on the same landscape from different angles… learning to trust each other’s sight.” Both systems distrust a single source’s claim and require agreement across independent observers before treating something as real. JP formalizes this into a numeric confidence score; Basque JOY keeps it as a relational practice with no scoring system at all.
Phases/stages as a shared structural device
Both use a phase model to describe progress toward a mature, reproducing indigenous church, and the phase logic is almost parallel:
- JP’s 0–7 Engagement Scale runs from Entry through Evangelism, Discipleship, Local Church, Reproducing Church, Multiplying Church, to Phase 7 Sustained Gospel Presence, with each phase keyed to observable activity types (baptisms, church starts, second-generation plants, cross-cultural sending).
- Basque JOY’s four movements — Reading the Soil, Tending the Soil, Noticing the Kingdom, Building the Trellis — run toward the same endpoint (an indigenous, self-sustaining, sending community) but each transition is triggered by qualitative “indicators of transition” (a list of signs like “new tables forming without the catalyst meeting them”) rather than an activity count crossing a threshold.
So both frameworks think in stages toward reproducing/multiplying indigenous church as the goal, and both treat the outside worker becoming unnecessary as the success condition, but JP operationalizes stage transitions as countable ministry activity, while Basque JOY operationalizes them as relational/trust signals judged communally.
Handling of uncertainty and unknowns
JP is explicit and almost statistical about this: the new UUPG list uses two confidence tiers, strong confidence, where groups have been cross-referenced with partner organizations whose systems specifically record engagement status, and preliminary confidence, where Joshua Project has no, limited, or incomplete reports and defaults to “unengaged” as a conservative starting assumption rather than a verified conclusion. Uncertainty gets a tag, not a narrative.
Basque JOY handles unknowns through posture and humility rather than a labeling system — the catalyst is trained to assume misreading is likely, to seek out “cultural guides who will tell the outside catalyst the truth about when their outside perspective is producing misreadings,” and success in Reading the Soil is partly measured by how often correction actually happens. It’s the same underlying worry (our picture of reality may be wrong) solved by building humility into personal formation instead of into a database schema.
Scale and worldview-diagnosis methods
JP’s Cultural Insights Accelerator formalizes worldview diagnosis into a fixed six-category grid (Theology, Metaphysics, Epistemology, Ethics, Anthropology, History) paired with a lookup table of “fault lines” and matching “Gospel bridges” by religion (Islam → Assurance/Adoption, Buddhism → Dignity/Restoration, etc.) — a reusable, cross-context taxonomy meant to scale across thousands of people groups.
Basque JOY does something structurally similar but deliberately non-transferable: it reads one specific culture’s “soil” (kuadrilla, txoko, Basque refusal of homogenization) as containing “seeds” and, separately, “patterns that need to die” — but it resists turning that into an exportable matrix. It’s a one-culture theological ethnography, not a generalizable diagnostic tool. Where JP is designed for breadth across 10,421+ groups, Basque JOY is designed for depth in one, and explicitly disclaims being “a missional methodology imported from another context and adapted for Basque use.”
Where the underlying tension actually surfaces
Basque JOY’s own “pushback” section names the very gap that separates it from something like JP+: it anticipates the criticism that its framework has “no explicit gospel presentation, altar call, or conversion moment” and no scorecard tied to “quarterly reporting cycles” — which is close to a direct rebuttal of JP’s entire orientation toward countable engagement phases and reportable activity data. JP’s whole raison d’être this quarter is soliciting more numeric submissions (“we need thousands of submissions by year-end”); Basque JOY’s document argues that the crossing from unbelief to faith “is the Spirit’s work, sovereign and often unpredictable” and explicitly refuses to schedule or measure it.
In short: JP+ is a global-scale, database-driven engagement tracker built for prioritization and resource allocation across thousands of groups, using activity counts and multi-source convergence to assign confidence. Basque JOY is a single-culture, relationally-driven formation framework built for depth and indigeneity in one context, using narrative “indicator” convergence and communal discernment instead of any numeric metric — and it treats JP-style metrics as part of the problem it’s trying to avoid.
Discussion Topics
I’d like to set aside time to discuss two mission frameworks that take almost opposite approaches to the same goal, and I think a conversation would sharpen how we think about our own measures of progress.
The two sources:
– Joshua Project’s JP+ Quarterly Report (Phase of Engagement scale, UUPG data, translation counts)
– Basque JOY’s ministry framework (“Raices/Sustraiak” and “Walking the Four Phases”)
A few points worth talking through:
Similarities
– Both use staged models toward the same end goal: an indigenous, reproducing, self-sustaining church.
– Both build confidence through convergence of multiple observers rather than trusting a single report.
– Both treat the outside worker’s eventual unnecessariness as a marker of success.
– Both include a structured way of diagnosing a culture/worldview before acting.
Differences
– JP+ measures with numbers (group counts, translations, phase tallies); Basque JOY measures with qualitative relational signals and explicitly rejects numeric metrics.
– JP+’s confidence system is a formal tiered score; Basque JOY’s is a relational debrief practice with no scoring.
– JP+ is built for breadth across thousands of groups; Basque JOY is a deep, single-culture, non-exportable framework.
– JP+ centers reportable ministry activity; Basque JOY centers posture, presence, and explicitly leaves the moment of conversion unscheduled.
Would love to get a group together to unpack where each approach is strong, where it has blind spots, and what it means for how we track our own work. Let me know a time that works for you.

A Critical Assessment
How JP+’s approach could assist outreach in the Basque Country
- Worldview diagnosis tools transfer well. The six-category framework (Theology, Metaphysics, Epistemology, Ethics, Anthropology, History) and the “fault line → Gospel bridge” method could genuinely sharpen Basque JOY’s soil-reading work. JP+ explicitly develops this for Islam, Buddhism, Hinduism, animism, and secular materialism — that last one is the closest match to a post-Christian, disenchanted Basque context, and having a structured fault-line/bridge pairing (Foundation: “hunger for justice is evidence of the map being denied”) gives Basque catalysts a sharper diagnostic vocabulary than “depleted soil” alone provides.
- Scripture-in-heart-language research is directly relevant. JP+’s piece on trade language vs. heart language vs. local idiom translation maps almost exactly onto Basque JOY’s own emphasis on Euskara — “learning Euskara as an act of love rather than a missional tool.” JP+ adds empirical backing (Kekchi in Guatemala, Muslimani Bengali) that heart-language engagement is what produces durable movements, which strengthens the theological instinct Basque JOY already has.
- The Church Media Kit and Light the Nations prayer map are low-cost mobilization tools Basque JOY could use to raise awareness and prayer support among sending churches without adopting any of JP+’s measurement philosophy.
- The convergence-based confidence model (multiple independent reports before trusting a phase assignment) is a method, not just a metric, and Basque JOY’s own debrief practice could formalize itself further by borrowing this logic even while keeping it qualitative.
How JP+’s approach could inhibit outreach in the Basque Country
- Category mismatch at the root. JP+’s entire architecture — Frontier vs. Unengaged, the 0.1% Christian threshold, the UUPG list — is built for populations with near-zero historical gospel access. The Basque Country is the opposite case: over a thousand years of Christian presence, a “depleted, not dead” soil rather than an unreached one. Applying JP+’s classification system risks either mislabeling the region (it likely doesn’t register as Frontier or UUPG at all) or, worse, importing an unreached-peoples urgency and strategy stack that doesn’t fit a post-Christendom deconversion context.
- Metrics-first culture cuts against Basque JOY’s central conviction. JP+ is oriented around reportable activity (baptisms, church starts, second-generation plants) feeding a phase score. Basque JOY explicitly argues that this kind of measurement “creates pressure toward the kind of scale and speed that depletes soil rather than restoring it.” If a sending organization evaluated Basque work by JP+-style quarterly reporting expectations, it would directly undermine the “decades, not quarters” timeline and the refusal to schedule conversion moments that Basque JOY treats as non-negotiable.
- The organizational bulk-submission and GAPP activity model assumes visible, trackable ministry activity(gospel shares, baptisms, discovery groups). Basque JOY’s method is largely invisible by design in its early phases — meals, noticing, small slow steps — precisely the kind of activity that wouldn’t generate the volume of data JP+ needs for a confident phase assignment. Trying to fit Basque work into JP+’s reporting pipeline could pressure the movement toward more legible, scorable activities at the expense of its own theological commitments.
- JP+’s split-by-social-barrier methodology (e.g., Egyptian Arab Muslim vs. Coptic) has no clean analog for Basque identity, which is a linguistic/cultural category, not a genuine intra-group barrier in the same sense — misapplying that kind of splitting logic could fragment rather than clarify the Basque strategic picture.
- Frontier People Group prioritization language (“this deserves utmost priority”) could crowd out a secularized, historically-Christian region entirely in resource allocation decisions if Basque work is evaluated by the same “31% of unreached, 97% Muslim/Hindu” prioritization logic that JP+ uses to argue for where mission dollars should go.
Net effect: JP+’s diagnostic and linguistic tools are genuinely portable and would sharpen Basque JOY’s methodology; its measurement philosophy and people-group classification system are built for a different missiological category of place and would, if applied directly, work against the very posture Basque JOY is trying to protect.
DMM Continues the Conversation
Adding DMM (Disciple Making Movements) as a third lens sharpens the contrast nicely — it sits methodologically closer to JP+ than to Basque JOY, even though its language sounds relational.
What DMM measures
DMM’s core metric is generational multiplication of disciples/churches. The standard definition requires sequential generations of growth — when an original disciple or church produces a new one, that’s one generation — with a movement or church-planting movement (CPM) formally identified only once there are at least four successful direct generations, growing dynamically, and exceeding a scale threshold — roughly 1,000 believers for a DMM or 100 churches for a CPM. Some practitioner networks operationalize this even more tightly: Zúme’s own target is four generations of groups and 75 groups with 500 disciples within three years, and Watson & Watson’s classic CPM definition requires a minimum of one hundred new locally initiated and led churches, four generations deep, within three years. Some agencies add a “multiple streams” requirement so the count isn’t just one lucky chain — many separate branches must independently reach the fourth generation. The overriding practitioner ethos is captured well: DMM strategists are explicitly “not counting Sunday attendance, money in the offering plates, and participation in programs as much as they’re counting generations of disciples” — obedience and reproduction, not attendance.
Where DMM lines up with JP+
DMM is, structurally, a metrics-first framework almost as much as JP+ is — it just counts a different unit (generations and streams instead of engagement phases and translated scripture). Both:
- Define success by a numeric threshold crossed within a bounded timeframe (JP+’s phase scale; DMM’s “4 generations / 100 churches / 3 years” formula).
- Use scale and speed language as a mark of legitimacy — DMM proponents describe their aim in terms of “rapid and exponential increase in disciples making disciples” and “rapid multiplication,” echoing JP+’s urgency around unengaged-group counts.
- Build researcher/network aggregation systems that tally movements globally — Lausanne-affiliated researchers report over 1,950 known mature movements and 100+ million professing disciples, a database exercise very close in spirit to JP+’s people-group tallying.
Where DMM lines up with Basque JOY instead
Despite the numeric backbone, DMM’s process language sounds much more like Basque JOY than like JP+: obedience-based discipleship, indigenous leadership, and the outside worker’s deliberate self-removal once locals are equipped are all named as non-negotiables — for instance, when used cross-culturally locals are encouraged to lead the groups and the one who brought the good news leaves after some time. That’s the same “make yourself unnecessary” success condition Basque JOY and JP+ both share, arrived at through DMM’s obedience/multiplication logic rather than Basque JOY’s soil/trellis metaphor.
The tension DMM makes visible that neither other document states outright
DMM has attracted the same internal critique Basque JOY levels preemptively at itself. Critics argue the focus on speed and scope makes DMMs vulnerable to patterns of thinking shaped by Western secularism, and that setting hard numeric targets risks implying that slower, more traditional mission approaches were simply deficient — almost verbatim the objection Basque JOY raises against JP+-style reporting pressure. So DMM is a useful third point precisely because it shows that “counting generations instead of counting engaged people-groups” doesn’t escape the metrics-vs-relationship tension — it just relocates it. Basque JOY’s approach reads as a more thorough rejection of any numeric threshold, including DMM’s, since a depleted-soil, post-Christendom, generational-trauma context is arguably the least suited of all mission fields to a 3-year/4-generation growth clock.
One likely discussion flashpoint
Basque JOY would almost certainly object to DMM’s obedience-based, rapid-reproduction model as still too speed-oriented for Basque soil — but DMM’s insistence on indigenous leadership and worker withdrawal is arguably its strongest overlap with Basque JOY’s own convictions. That makes DMM a good test case for the group: does Basque JOY reject DMM’s numeric thresholds while still borrowing its discipleship mechanics, or does it consider the whole DMM package too tainted by the metrics culture it’s built around?
Name the funding/accountability question directly
This is the real pressure point, so let’s work it directly rather than leave it as a discussion prompt.
The core bind
A sending agency’s board, by default, wants JP+-style reportables: engaged/not-engaged status, activity counts, phase progression, something that trends upward on a quarterly cadence. Basque JOY’s own document names the danger explicitly — pressure toward “the kind of scale and speed that depletes soil rather than restoring it” — and treats decades, not quarters, as the honest unit of time. Those two clocks don’t reconcile on their own terms. Forcing the work into quarterly reportable metrics either produces false positives (activity inflated to satisfy the report) or honest reports of “nothing measurable happened,” which erodes donor confidence over time even when the work is sound.
Where DMM actually offers a partial answer
DMM’s generation-counting is closer to Basque JOY’s timescale problem than JP+’s phase scale is, because a generation is a real event, not an activity tally — but DMM still assumes multiplication will be visible within a few years, which doesn’t fit depleted-soil, post-Christendom terrain either. So DMM isn’t a ready-made solution, but its instinct — track discrete real events, not activity volume — points toward a workable compromise.
A practical way to satisfy accountability without distorting the work
- Report process indicators, not outcome metrics, on the quarterly cycle. Basque JOY’s own “indicators of transition” (new tables forming without the catalyst present, a Basque participant correcting the catalyst’s misreading, a rhythm surviving the catalyst’s absence) are discrete, nameable, dateable events. They can be logged quarterly like JP+ data points without being outcome-inflated, because they describe posture and trust-building, not conversions.
- Separate the reporting cadence from the evaluation cadence. Log qualitative indicators quarterly (for continuity and donor engagement), but set the actual strategic evaluation — is this working, should it continue — on a multi-year horizon that matches the soil-restoration timeline. This mirrors how JP+ itself distinguishes engagement-phase updates (frequent) from a Frontier/UUPG designation (which persists for years).
- Use JP+’s confidence-tiering logic, inverted. JP+ tags data as “strong confidence” vs. “preliminary confidence” rather than forcing everything into one certainty level. A Basque JOY report could do the same — tag each quarter’s update as a “signal” (something noticed) versus a “milestone” (something confirmed through two-source convergence in the debrief practice) rather than presenting all updates as equally weighted outcomes.
- Pre-negotiate the metric with the sender before the term begins, not during it. The distortion risk is highest when a worker discovers mid-term that the board expects JP+-style numbers and scrambles to produce them. If the qualitative indicator set is agreed as the reporting standard up front, with an explicit rationale (citing the depleted-soil framing), the worker isn’t retrofitting an answer to a mismatched question each quarter.
- Give the sender a small number of hard trip-wires, not a scorecard. Rather than many soft metrics, agree on 2–3 concrete signals that would indicate the work should be reconsidered (e.g., zero relational access after X years, no local person willing to host a gathering) — this gives the funder a genuine accountability mechanism without requiring the worker to manufacture positive-sounding activity data every quarter.
What this doesn’t solve
No version of this fully removes the tension — a board that fundamentally wants JP+-style growth numbers will eventually be dissatisfied with “we had a good conversation and someone corrected our assumption about kuadrilla dynamics” as a quarterly update, no matter how well-framed. The honest answer for the discussion is probably: this only works with senders who’ve already bought into the depleted-soil framing theologically before the reporting relationship starts. Reporting design can reduce distortion, but it can’t substitute for the sender agreeing in advance that the clock is decades, not quarters.
Reflection: The Unique Situation in Approaching Basque Culture
There’s a paradox at the center of Basque ministry that most mission frameworks aren’t built to hold: this is not virgin soil, and it is not settled soil either. It’s something in between that resists both of the categories missiology usually reaches for.
Neither frontier nor fully reached. Every framework surveyed in this conversation — Joshua Project’s Frontier/UPG thresholds, Moody’s unreached-peoples urgency, WEC’s “no opportunity to hear” rationale — is built around a binary: either a people has meaningful gospel access or it doesn’t. The Basque Country breaks that binary. There’s a thousand years of Christian presence, an indigenous saint (Ignatius of Loyola) born from this exact soil, and church buildings in every town. And yet the JP+ report’s own honest admission — that Phase of Engagement data doesn’t even exist yet for most of Western Europe — points at something real: institutional presence and living gospel movement are not the same measurement. JOY’s phrase for this is the sharpest one available: depleted, not dead. That’s a category most frameworks don’t have room for, because most were built for either “reached” or “unreached,” not for “once reached, now cooling.”
The identity fault line isn’t the usual one. Nearly every worldview-diagnosis tool in this conversation assumes the fault line runs through belief — assurance in Islam, dignity in Buddhism, grace in Hinduism. Basque culture’s fault line runs somewhere else: through belonging. Centuries of political suppression, a language with no linguistic relatives on earth, a fierce, specific refusal to be absorbed into something generic — this is an identity built on survival against erasure, not a theology in need of correction. That changes what “good news” even sounds like. A Gospel bridge built on assurance-before-God lands as an abstraction. A Gospel bridge built on belonging that survives, that isn’t absorbed, that doesn’t erase you — that’s the shape of what this culture is actually straining to hear. JOY’s instinct to build around kuadrilla and txoko rather than doctrine-first isn’t a theological softness. It’s a recognition that the wound and the hunger here are relational before they are propositional.
The very asset that makes evangelism possible is what makes it slow. The kuadrilla’s lifelong loyalty is precisely why it’s such a promising analog for church — and precisely why nothing shortcuts trust inside it. A culture that has survived by tightly guarding who’s in and who’s out will not fast-track a stranger’s message, no matter how urgent that stranger’s sending agency considers the need. This is where Moody’s dispensational urgency and JOY’s “the oak doesn’t grow in a day” conviction genuinely collide, and neither one is simply wrong. The Great Commission’s urgency is real. So is the fact that trust in this specific culture is not extractable by urgency — it has to be earned at the culture’s own pace, over years, inside relationships that already existed before the missionary arrived.
Language is doing more work here than almost anywhere else in this report. In most frontier contexts, the missing ingredient is any translation at all. In the Basque Country, Euskara Bible resources already exist. The gap isn’t access to Scripture — it’s whether ministry actually happens in the heart language or defaults, out of convenience, to Spanish or French, the trade languages surrounding it on both sides. That’s a subtler failure mode than “no Bible in their language.” It’s the failure of comprehension standing in for transformation — exactly the trap the Phases of Engagement Toolkit warns about — but here it’s compounded by the fact that Euskara isn’t just a heart language. It’s a four-thousand-year-old marker of not being conquered. Ministering in Spanish, however fluent, risks quietly repeating the very cultural absorption Basque identity has spent centuries resisting.
What this means for anyone measuring “progress.” Every metric this conversation has touched — Christian Adherent percentage, Phase of Engagement, baptism-to-leadership ratios — assumes forward motion is visible on a normal mission timeline. Basque ministry may be the case where the metrics themselves need the longest possible patience before they mean anything, not because the field is unusually resistant, but because what’s being asked of the culture — to receive something new from outside without it costing them their distinctiveness — is a genuinely harder question than “will you believe this,” and it is answered, if it’s answered at all, one kuadrilla and one generation at a time.
The unique situation, in the end, is this: Basque ministry doesn’t need a better argument or a faster strategy. It needs someone willing to stay long enough, in the actual language, inside the actual kuadrilla, for the culture to test whether this Jesus can be received without being erased by him. That is a different kind of task than reaching an unreached people, and it may be a harder one — closer to re-earning trust than to first contact.
