Type: supporting argument (off-timeline) · Assessment: plausible — the historical thesis weighed here is that, alongside the well-documented contraction of the rite's recipient (healing→dying — see the narrowing thesis), the Latin West also contracted its minister: where the earliest authoritative gloss let "all Christians" anoint with the blessed oil in necessity (Innocent I, echoed by Bede), the medieval and Tridentine church reserved the anointing to the ordained priest alone ("The minister of this sacrament is the priest"). A real and datable contraction of who may administer does occur — but it is narrower and more qualified than the recipient-narrowing, and it is overstated if pressed into "the church took away James's own provision," since James 5:14 itself names the elders of the church, not any Christian. Coherent and grounded, but short of the airtight, self-reversed certainty of the recipient thesis (plausible).

James 5:14 has the sick person "call for the elders of the church" to anoint and pray. In the early centuries the oil, once a bishop had blessed it, could be applied even by lay Christians "in their own necessity or in that of their [people]" — so the pope himself ruled, and Bede three centuries later repeated it. The medieval West then progressively reserved all anointing with the holy oil to the priest, until Florence and Trent defined the minister as the priest and read James's "elders" as ordained presbyters, "not the elders by age, or the foremost in dignity amongst the people." The Latin church, on this thesis, contracted the who-may-administer of James's rite just as it contracted the to-whom: a second, independent narrowing.
The point is drawn straight from the primary texts by liturgical historians of the sacrament (Frederick Paxton on the reform books that reserve anointing to priests; Paul Meyendorff on the lay-anointing tradition Innocent attests), and it is the natural companion to the recipient-narrowing that the Catholic Church itself conceded at Vatican II. Unlike the recipient-narrowing, though, this one was never reversed: current Catholic law still restricts valid anointing to a priest, so the thesis is a claim about a completed contraction, not a there-and-back arc.
The early permission is broad. The earliest authoritative gloss on James 5:14, Innocent I to Decentius of Gubbio (416), rules that the blessed oil "it is permitted not only to priests but also to all Christians to use for anointing in their own necessity or in that of their [people]," the "elders" being named only because bishops "cannot go to all the sick." Three centuries later Bede (c. 710) copies the permission verbatim into the standard Latin commentary on James: "Not only the presbyters, but as Pope Innocent writes, also all Christians are permitted to use the same oil to anoint in their own or their relatives' necessity, though this oil may only be consecrated by bishops."1 The reservation to priests is legislated and then dogmatized. The Carolingian reform assigns the rite to presbyteri as a standing duty (the Council of Chalon, 813: "the sick ought to be anointed by priests"); the scholastics make the priest the sole minister (Aquinas: the minister is a priest, "not a layman, not a deacon"); and the councils define it — Florence (1439), "The minister of this sacrament is the priest," and Trent (1551), "the proper ministers of this sacrament are the Presbyters of the Church; by which name are to be understood, in that place, not the elders by age, or the foremost in dignity amongst the people, but… bishops, or priests by bishops rightly ordained."2 Between Innocent's "all Christians" and Trent's "priests… rightly ordained" the field of who may lawfully anoint demonstrably contracts.
What holds. The administrative contraction is real and datable. A permission that Innocent granted and Bede transmitted — lay application of the episcopally-blessed oil in necessity — is simply gone by the high middle ages, closed off by a priest-only rule that Florence and Trent then defined. That much is documented from the sources and is not seriously in dispute; it is a genuine second axis of the Latin narrowing, distinct from the shift in recipients.
What would overstate it. Three cautions keep the thesis honest, and together they pull it below the "sound" of the recipient-narrowing. (1) James named the elders. The proof-text itself says "call for the elders (presbyterous) of the church," so the priest-only endpoint tracks James's own words — it is Innocent's broad lay-permission that is the departure from James, an emergency extension beyond the apostle's "elders," never a lay celebration of the full rite. Framed as "the church contracted James's provision that any Christian may anoint," the thesis is false: James gave no such provision. Framed as "the church contracted the wider lay-administration that Innocent and Bede attest," it is true.3 (2) Even the early permission reserved the core. Innocent and Bede allow laity to apply the oil, but only oil a bishop has consecrated, and only "in necessity" — the blessing of the oil, and the elders' proper rite, were episcopal-and-presbyteral throughout. The narrowing is of a real but limited lay privilege, not of the sacrament's ordinary ministry, which was clerical from the start. (3) No Eastern control case, and no reversal. The recipient-narrowing is sealed by two facts this one lacks: the Greek euchelaion is a control that never narrowed the recipients, and Rome itself reversed the contraction at Vatican II. On the minister question neither holds — the East, too, reserves the anointing to priests (ideally seven), so there is no non-narrowing control, and the Latin priest-only rule was never undone: current Catholic law still provides that "every priest, and a priest alone, validly administers the anointing of the sick." The absence of a reversal is not evidence the contraction did not happen, but it removes the church's-own-admission that made the recipient thesis airtight.4
Plausible. A real contraction of the rite's minister did occur in the Latin West — from the lay-anointing permission Innocent granted and Bede transmitted to the priest-only rule of Florence and Trent — and to that extent the thesis of a second, minister-narrowing holds and is worth setting beside the recipient-narrowing. But it should be held to its true and modest claim. It overreaches if pressed into "the church narrowed James's own allowance that any Christian may anoint," for James named the elders; the thing that contracted was a qualified patristic-Latin lay permission (application of already-blessed oil, in necessity), and the endpoint actually aligns with James's "elders." With no Eastern non-narrowing control and no self-reversal to seal it — the two props that make the recipient-narrowing sound — the minister-narrowing is coherent and grounded but short of that certainty (plausible).
