The Core Assumption
Meaning lives in the things Scripture narrates as well as in its words, so one passage truly bears literal, allegorical, moral, and anagogical senses.
The Four Assumptions
- Where meaning lives
- Meaning lives in both the words and the things the words signify, since God, the author of Scripture, can make events themselves carry further meaning.
- What the text is
- The text is a divinely authored book in which historical things, as well as words, are signs ordered to faith, morals, and final hope.
- Who may interpret
- The interpreter is the church's trained reader, formed by the liturgy, the fathers, and the schools, who reads within the faith of the whole body.
- What counts as a good reading
- A reading is adequate when all four senses cohere, the spiritual senses build on a sound literal sense, and nothing contrary to faith or charity is concluded.
Genealogy
This method arose in the medieval period (5th century origins, standard from the 12th to 16th centuries).
Key proponents: John Cassian, Gregory the Great, Thomas Aquinas, Nicholas of Lyra.
Key texts: Conferences, Conference 14, by John Cassian; Moralia in Job by Gregory the Great; Summa Theologiae I, q.1, a.10, by Thomas Aquinas.
The Procedure
These are the same steps The Workshop will walk you through.
-
Establish the literal sense
State what the passage says and narrates at the level of words and events.
Why this step matters: Aquinas insists the spiritual senses are founded on the literal sense, and argument proceeds from the literal sense alone.
How to do it: Settle grammar, genre, and historical reference before moving to any spiritual level.
What goes wrong here: Building an allegory on a mistranslation or on an event the text never narrates.
You record: Literal sense. Done well when: The literal statement can be defended from the wording of the passage.
-
Draw the allegorical sense
State what the passage teaches about Christ and the church, the realities of faith.
Why this step matters: The allegorical sense relates the Old Testament's realities to their fulfillment in Christ and his body.
How to do it: Follow the classic example: Jerusalem is historically a city and allegorically the church; test proposed senses against the New Testament's own use of the passage.
What goes wrong here: Assigning Christological meaning to details the tradition and the text give no warrant for.
You record: Allegorical sense. Done well when: The sense concerns faith in Christ and the church and is consonant with the rule of faith.
-
Draw the tropological sense
State what the passage requires of the individual soul's conduct and conversion.
Why this step matters: The moral sense turns the text toward the reader's life, as Jerusalem signifies the faithful soul.
How to do it: Name the virtue to practice or the vice to abandon that the passage's reality figures.
What goes wrong here: Moralizing that ignores the passage and attaches a stock lesson to it.
You record: Tropological sense. Done well when: The required action is genuinely figured by the passage's content.
-
Draw the anagogical sense
State what the passage reveals about the last things and the glory to come.
Why this step matters: The anagogical sense lifts the reader toward eternal destiny, as Jerusalem signifies the heavenly city.
How to do it: Anchor the hope in the passage's imagery and in the church's eschatological teaching.
What goes wrong here: Speculative timetables or details about the end that the text does not supply.
You record: Anagogical sense. Done well when: The sense concerns final glory and stays within the bounds of received eschatology.
-
Order the senses and check coherence
Set the four senses side by side and verify that the spiritual senses rest on the literal and contradict neither faith nor charity.
Why this step matters: The quadriga is a discipline of ordered plurality, not four independent readings.
How to do it: If a spiritual sense cannot be traced back to the literal sense, mark it as a preacher's accommodation rather than exegesis.
What goes wrong here: Presenting all four senses as equally demonstrative in doctrinal argument.
You record: Ordered fourfold reading. Done well when: A reader can trace each spiritual sense to its root in the literal sense.
Inputs Required
- A biblical passage
- The classic fourfold scheme and its Jerusalem example
- Familiarity with the rule of faith and received tradition
Outputs Produced
- A four-level interpretation of one passage
- Material ordered for doctrine, preaching, and contemplation
Quality Criteria
Under this method, a good reading is one that meets these tests:
- Spiritual senses founded on the literal sense
- Coherence among the four senses
- Conformity to faith and charity
- Restraint where the text gives no warrant
Common Errors
- Forcing all four senses out of every verse mechanically
- Arguing doctrine from a spiritual sense alone, against Aquinas's own rule
- Multiplying senses without control from the literal text
Strengths
- It integrated doctrine, morality, and hope in a single act of reading Scripture.
- It gave medieval preaching and contemplation a disciplined way to hear the whole Christ in the whole Bible.
- In Aquinas's version it preserved the primacy of the literal sense for theological argument.
Weaknesses and Critics
- In weaker hands it licensed fanciful senses detached from the text.
- It presupposes a sacramental view of history that historical criticism does not share.
- Requiring four senses of every passage produces padding where a text bears fewer.
Martin Luther: Luther rejected the quadriga as a playground for arbitrary senses, insisting Scripture has one simple literal sense and that the fourfold scheme made the Bible a wax nose. (Lectures on Genesis and An Assertion of All the Articles, by Martin Luther)
John Calvin: Calvin charged that the fourfold method obscured the genuine meaning of Scripture with human inventions and praised instead the lucid brevity of the author's own sense. (Commentary on Galatians 4:22 and the Institutes, by John Calvin)
Internal Schools
Monastic lectio tradition: In monastic use, represented by Gregory the Great, the senses serve contemplation and moral formation more than disputation.
Scholastic regulation: Aquinas and the schoolmen formally subordinate the spiritual senses to the literal sense and restrict doctrinal proof to the literal sense.
Late medieval literalist correction: Nicholas of Lyra's Postilla recentered the literal sense, including its prophetic dimension, and influenced the Reformers.
Exemplar Readings
Cassian's Jerusalem (Galatians 4:22-31 as framework, applied to Jerusalem texts): Cassian's Conference 14 gives the textbook case: Jerusalem is literally the city of the Jews, allegorically the church of Christ, tropologically the human soul, and anagogically the heavenly city.
Gregory the Great on Job (Job 1-2 and throughout the Moralia): Gregory expounds Job's sufferings historically, then allegorically of Christ and the church, then morally of the trials of every faithful soul, modeling the layered reading for medieval preachers.
What This Method Cannot Do
The fourfold sense cannot demonstrate doctrine from its spiritual senses, on its own best theory, since proof belongs to the literal sense. It cannot recover the human author's intention where that intention is a different question from the divine author's ordering of events, and it cannot compel assent from readers who do not share its conviction that God writes with things as well as words.
Site Stance
The site has not yet assigned its stance on this method. The stance assignments wait on the named reviewers, the same naming the Christian Assessment verdicts wait on. The method stands here in full in the meantime: a stance discloses the site's judgment, and it never filters what a reader may read or run. The stance values and their criteria stand on the criteria page.
