The Reformation Index

A quantitative analysis of LDS General Conference discourse, 1942 to 2025. Seven metrics across 5,838 talks and 11.1 million words show language drifting toward mainstream Protestant patterns. Nelson is the largest single-era inflection point in 84 years of data, and he named the moment himself.

The dedication of the Rome Italy Temple is a hinge point in the history of the Church.
President Russell M. Nelson, March 2019, Rome Italy Temple dedication weekend (March 9-12, 2019). Reported by Church News and Deseret News. This dashboard measures whether the data agrees.

The Reformation Index

Each of the seven sub-metrics is rescaled 0–100 across all eras, then averaged. The composite ranges from 0 (peak LDS distinctiveness) to 100 (peak Protestant convergence). Read the methodology section below for the exact formula.

What this is, and what it is not. The index is a relative measure across 11 eras of LDS data, not an absolute claim about how Protestant the Church has become. A score of 89 under Nelson means his era sits 89% of the way from the most-LDS-distinctive era in the dataset (G.A. Smith at 4.0) to the most-Protestant-convergent score the data could yield. The composite has no hand-tuned weights and no hardcoded values. The formula is the same one applied to each prior era.

    Section 2

    Living Prophet vs. Joseph Smith

    Per-talk mention rate of the sitting president (matched by full name and "President <Surname>") versus mentions of "Joseph Smith" or "the Prophet Joseph." Quote-attribution rate counts mentions within 80 characters of a quoting verb (said, taught, wrote, declared, testified, counseled, etc.).

    The pattern shifts in magnitude, not direction. Hinckley and Monson were also quoted slightly more often than Joseph Smith (1.18 and 1.59 quotes per JS quote, respectively). What is new under Nelson is the size of the gap: 3.56 quotes per JS quote. Living-prophet quote-attribution is roughly 3x higher under Nelson than under Hinckley. Living-prophet mention rate (not just quotes) crosses the 1:1 threshold against Joseph Smith for the first time in the dataset.

    Mormon Distinctives vs. Protestant Vocabulary

    Distinctively LDS terminology (priesthood keys, plan of salvation, dispensation, sealing ordinance, etc.) versus generically Protestant phrasing (born again, personal relationship with Christ, by grace alone, etc.). Y-axis is the ratio of LDS-distinctive mentions per Protestant mention.

    The shift is additive, not reductive. The ratio narrows because Protestant vocab grows faster than LDS vocab, not because LDS vocab shrinks. Both increase per talk under Nelson. LDS-distinctive vocabulary still dominates Protestant phrasing in absolute terms (8:1 ratio under Nelson). The data shows Christ-centered Protestant-style language being layered onto preserved LDS distinctives, narrowing the gap without erasing it.

    Absolute counts: both vocabularies rising

    Same data, plotted as per-talk frequency rather than ratio. Both Mormon-distinctive and Protestant-style vocabulary increase under Nelson; the ratio narrows because Protestant grows faster, not because LDS shrinks.

    Section 4

    Grace vs. Works

    Grace share of grace+works language. Grace counted as the words grace, gracious, graciously. Works counted via salvation-context phrases only (works of righteousness, good works, obedience, keep the commandments, endure to the end, etc.) to filter generic uses of "work."

    Measures language, not theology. "Grace" appearing more often does not mean LDS theology has adopted Protestant sola gratia. LDS doctrine still teaches works as essential alongside grace. What this metric tracks is rhetorical balance: how much of conference-talk discourse leans on grace vocabulary versus obedience and commandment-keeping vocabulary. The Bednar-led grace push of the 2010s shows up here, then accelerates sharply under Nelson.

    Section 5

    Theosis: Hard Exaltation Share

    Share of "godhood" language that uses hard-theosis or exaltation framing (becoming gods, celestial kingdom, eternal increase, joint-heirs with Christ) rather than soft-theosis ("Christlike," "divine nature") or Protestant-replacement framing ("personal relationship with Christ").

    This is the longest-running trend on the dashboard. Hard exaltation language has been declining steadily since Grant. The Snow Couplet (As man now is, God once was; as God now is, man may become), King Follett discourse, and "the Gods" plural references all peak in the 1940s-50s and trend toward zero through every subsequent presidency. Nelson continues a 60-year drift rather than initiating a new one. Where Nelson differs is the substitute he and his apostles use: not soft theosis but explicitly Protestant-replacement language (relationship with Christ, come unto Jesus, my Savior).

    Liturgical Calendar

    References to traditionally Catholic/Protestant liturgical observances (Lent, Advent, Holy Week, Good Friday, Palm Sunday, Ash Wednesday) in conference. Context-aware regex filters out the verb "lent," "advent of Christ" (the LDS sense), and "second advent."

    This is the cleanest Nelson-specific signal on the dashboard. Pre-Nelson, the corpus contains essentially zero references to Protestant liturgical observances across 75 years and 5,330 talks. Under Nelson, in 7 years and 508 talks, there are 43 references. Palm Sunday alone goes from a handful pre-Nelson to 32 mentions in Nelson-era conferences. The shift is not a gradual drift, it appeared with Nelson's tenure.

    Section 7

    LDS Materialism vs. Generic Piety

    Hard-materialist Godhead claims (separate beings, bodies of flesh and bone, three distinct personages, First Vision physicality) versus generic Christian-piety phrasing (personal relationship with Christ, come unto Jesus, trust in the Lord, my Savior).

    Two trends, one accelerating, one slowing. Generic Christ-centered piety language has been rising steadily since McKay. Nelson continues that trend at roughly the same slope. The materialist Godhead claims (separate beings, body of flesh and bones, First Vision physicality) declined slowly through Hinckley and Monson and have nearly halved under Nelson. Per-talk first-vision references and three-distinct-beings claims are at their lowest rates in the dataset.

    Did Individual Apostles Shift?

    For each apostle who has at least 5 talks both before and during the Nelson era, we compare their average grace-share, generic-piety-per-talk, and liturgical-references-per-talk between the two windows. This tests whether the cohort-level shift was driven by individuals changing their language, or by a different cohort speaking under Nelson.

    The shift is uneven across speakers. Most apostles individually moved toward more grace and Christ-centered language under Nelson (Ballard +28pts, Holland +22pts, Uchtdorf +22pts, Andersen +15pts). Several barely moved (Eyring +2, Bednar +6). Notably, Nelson himself barely changed his own language (+0.8 grace points). And several moved AGAINST the trend (Stevenson -24, Oaks -14, Soares -12). The cohort-level shift is real but is not uniform; it is driven by specific apostles substantially changing their rhetoric.

    Each bar is one apostle's change in average grace-share between their pre-Nelson talks and Nelson-era talks (positive = more grace language under Nelson). Counts of talks shown in tooltip. Speakers with fewer than 5 talks in either window are excluded. Listed in order of magnitude.

    Methodology

    Every number on this dashboard is computed in the open. The corpus is the BYU Scripture Citation Index (8,834 talk IDs probed; 5,838 successfully parsed; 1942–2025; 11.1M words). Each talk is attributed to the LDS Church President alive on its conference date, not to its calendar year. Conference dates are the first weekend of April and October.

    Robustness check: does Nelson rank #1 under different weightings?

    Concern: the composite Reformation Index could be sensitive to methodology choices. We tested 8 alternative weighting and inclusion schemes. Nelson ranks #1 across all of them, with composite scores ranging from 92 to 99.

    Schemes 2-4 multiply individual metrics by 6 (vs default 1) so that single metric carries 50% of the composite. Schemes 5-7 exclude specific eras or metrics. Scheme 8 takes the median rank across single-metric rankings instead of using the composite.

    Scaling baseline: 11 prophet eras (Grant through Nelson), Oaks excluded

    The composite uses min-max scaling. The baseline is the range of values observed across the 11 presidencies Grant through Nelson. The Oaks era (34 talks in October 2025, post-Nelson) is computed and shown but is not part of the scaling baseline because it is a successor cell, not a peer presidency. If Oaks were added to the scaling baseline, Nelson's score would compress from 97 to 89, but the rank ordering does not change.

    What is "regex"?

    Regex (short for "regular expression") is a precise pattern-matching language used in software to find text. It is how this dashboard counts how many times a phrase like "President Nelson" or "personal relationship with Christ" appears in millions of words of conference transcripts. A regex like \b(grace|gracious|graciously)\b means "match the word grace, or gracious, or graciously, but only as standalone words" (the \b tokens are word boundaries that prevent false matches inside longer words like "disgrace"). Every metric on this dashboard uses regex to count specific patterns, with documented patterns listed in each method block below so anyone can audit or reproduce the counts.

    Composite formula

    Each of the seven sub-metrics is min–max scaled across the 11 prophet eras (Grant…Nelson). Sub-metrics with negative polarity (where higher value = more LDS) are inverted to 100−x. The seven scaled values are averaged with equal weight.

    No hand-tuning, no era-specific weights, no hardcoded values. Formula is identical to the per-year Reformation Index shown on the chart.

    1. Living Prophet vs Joseph Smith

    Living-prophet regex: e.g., \b(?:President\s+)?Russell\s+M\.?\s+Nelson|\bPresident\s+Nelson\b. Joseph Smith regex: \bJoseph\s+Smith(?:\s+(?:Jr\.?|Junior))?|\bthe\s+Prophet\s+Joseph\b (filters out unrelated mentions of "Joseph"). Quote attribution = mention within 80 characters of a quoting verb (said, taught, wrote, declared, testified, counseled, etc.).

    Denominator: per talk.

    2. Mormon vs Protestant Vocabulary

    Mormon distinctives: dispensation, priesthood keys, plan of salvation, sealing ordinance, melchizedek priesthood, aaronic priesthood, first vision, urim and thummim, Book of Mormon, three degrees of glory, premortal, Council in Heaven, Word of Wisdom, etc. Protestant generics: born again, personal relationship with Christ, sola gratia / fide / scriptura, give your heart to Christ, accept Jesus, walk with the Lord, my Savior, etc.

    Denominator: ratio of Mormon to Protestant counts per era.

    3. Grace vs Works

    Grace: \b(grace|gracious|graciously)\b. Works: salvation-context phrases only: works of righteousness, good works, by our works, keep the commandments, obedience, endure to the end, work out your salvation. Generic uses of "work" are excluded.

    Reported as grace / (grace + works) percentage and as works:grace ratio.

    4. Theosis Categories

    Hard theosis: become gods, gods in embryo, the Gods, exalted being, King Follett, Snow Couplet. Exaltation: celestial kingdom, eternal increase, joint-heirs with Christ. Soft theosis: Christlike, divine nature, become like Christ. Protestant replacement: personal relationship with Christ, come unto Jesus, my Savior.

    Reported as (hard + exaltation) share of all four godhood categories.

    5. Liturgical Calendar

    Lent: capitalized only, with verb-form filter (rejects "lent his hand," "had lent") and religious-context boost. Advent: capitalized only, rejects "advent of Christ" (LDS sense) and "second advent." Holy Week, Good Friday, Palm Sunday, Ash Wednesday: literal phrase match.

    Total references and per-talk rate.

    6. LDS Materialism vs Generic Piety

    Materialism: body of flesh and bones, three distinct beings/personages, First Vision, two personages, embodied God. Piety: personal relationship with Christ/Jesus/God, come unto Christ, trust in the Lord, my Savior/Redeemer.

    Per-talk rates, both lines on chart.

    Conference-by-conference attribution (vs v1 dashboard)

    Each talk is attributed to whichever LDS Church President was alive on the conference date. Notable corrections vs the v1 dashboard:

    Known corpus gaps

    1957 October conference is missing entirely from the BYU corpus. Some 1980s April conferences are short by 5–10 talks. BYU appears to exclude sustaining-of-officers, statistical reports, opening/closing prayers, and choir interludes. This is appropriate for word-frequency analysis. The v1 dashboard's count of 6,251 talks likely included non-doctrinal entries; the audited count is 5,838.
