Lecture 269

269. Purifications of the Old Law: Spiritual and Bodily Uncleanness

Summary
This lecture explores Thomas Aquinas’s analysis of the purifications prescribed in the Old Law, distinguishing between spiritual uncleanness (arising from sin) and bodily uncleanness (arising from contact with sources of corruption). Berquist examines the literal reasons for these purifications—reverence for sacred things, avoidance of idolatry, health considerations—and their figurative meanings as signs of spiritual realities. Special attention is given to the red heifer sacrifice and the Day of Atonement, with detailed exposition of how these Old Law practices prefigure Christ’s passion and the sacraments of the New Law.

Main Topics #

Two Types of Uncleanness in the Old Law #

  • Spiritual uncleanness (maior immunditia): corruption of mind through sin—requires expiation by sacrifice for sin
  • Bodily uncleanness (minor immunditia): from contact with unclean things—requires only sprinkling of water
  • These impede access to divine worship (cultus divinus), either in the mind’s devotion to God or in bodily sacrifices and offerings

Sources of Bodily Uncleanness #

  • Death and corpses: body regarded as unclean because death is corruption
  • Leprosy: from putrefaction of fluids that corrupt the flesh
  • Menstrual flux: women undergoing blood flow considered unclean
  • Male seed: through infirmity, nocturnal pollution, or intercourse
  • Contact with unclean things: whatever touches unclean becomes unclean
  • Inanimate things: houses, vestments, vessels can contract uncleanness from corruption or contact

Literal Reasons for Purifications #

  1. Reverence for sacred things: Just as people do not handle precious objects with soiled hands, the unclean must be purified before approaching divine worship
  2. Avoidance of idolatry: Gentiles used human blood and seed in sacrifices to idols; the law prohibits such practices
  3. Health and contagion: Leprosy and other corruptions spread; the law protects the community
  4. Distinction from defilement: Avoiding association with lepers and infirm peoples whose sickness was abominable

Figurative Meanings of Bodily Uncleannesses #

  • Uncleanness of corpses → uncleanness of sin (death of the soul)
  • Leprosy → heretical doctrine (contagious, mixed true and false like leprosy’s patchy appearance)
  • Menstrual flux → idolatry
  • Male seed → unclean speech
  • Coition → original sin (transmitted to offspring)
  • Contact with unclean things → consent to another’s sin (per 2 Cor 6:17: “Go forth from the middle of them and be separated”)

The Red Heifer Sacrifice (Numbers 19) #

Historical Context #

  • Offered in memory of Israel’s sin in worshipping the golden calf (Aaron’s sin)
  • Performed outside the camp (as Christ suffered outside the gate)
  • Priest (Eleazar) handed the sacrifice to be immolated
  • Ashes collected by a clean man and mixed with living water for purification

Literal Significance #

  • Red color: represents the corruption of idolatry that must be burned away
  • Cedar wood: does not easily corrupt; retains integrity
  • Hyssop: retains odor after drying
  • Scarlet/twice-dipped thread (coccus): dyed in water, signifying the elements
  • Four elements signification: Cedar (earth), hyssop (air via odor), coccus (water via dye), fire (burning)
  • Those who sprinkle become unclean, breaking infinite regress: one who sprinkles must be cleaned by another

Figurative Meanings (Ratio Figuralis) #

  • Red cow = Christ according to His infirmity (feminine sex)
  • Redness = blood of His passion
  • Integral age, no blemish, unbroken yoke = Christ’s perfect operation without sin
  • Cedar, hyssop, scarlet = height of hope, humility/faith, charity—virtues through which we adhere to Christ’s suffering
  • Living water mixed with ashes = baptism receiving power from Christ’s passion
  • Sprinkling seven times = universality (seven days of the week) and perpetuity of Christ’s cleansing power “unto vespers”—until the end of the world
  • Those performing sacrifice become unclean = Jews made unclean by killing Christ, yet through this our sins are expiated

The Paradox of Unclean Purification #

  • The priest and those handling the sacrifice contract uncleanness
  • Yet their actions purify others
  • Signifies that Christ’s passion, though appearing as death and corruption, cleanses us from sin
  • The uncleanness remains “usque vespers” (until evening/end of present life) because those treating sacred things for others’ cleansing contract uncleanness themselves

The Day of Atonement (Yom Kippur) #

Ritual Elements #

  • Celebrated on tenth day of seventh month (once yearly)
  • High priest first offers sacrifice (calf) for himself, commemorating Aaron’s sin with golden calf
  • Ram offered in holocaust, signifying priestly prophecy ordered to God’s honor
  • Two goats offered for people’s sins

Purification and Forgiveness #

  • Necessary because priests have weakness and need expiation before offering for people
  • Goats represent the animal suited to bearing sins (as in Luke 15’s parable of prodigal son)

Important Definitions #

Immunditia (Uncleanness) #

Two-fold:

  1. From corruption of mind or body (maior immunditia)—requires sacrifice
  2. From contact with unclean things (minor immunditia)—requires water sprinkling

Cultus Divinus (Divine Worship) #

Two-fold:

  1. Spiritual: devotion of mind to God
  2. Bodily: sacrifices, offerings, and other material actions

Aspersion (Sprinkling) #

The ritual sprinkling of water (sometimes mixed with ashes) for purification; related to reverence and the phrase “casting aspersions”

Examples & Illustrations #

Woman with Hemorrhage (Gospel Account) #

  • Woman suffering menstrual flux approaches Christ and touches His garment
  • Required courage despite being ritually unclean
  • Christ heals her, demonstrating His power to transcend Old Law restrictions
  • Shows Christ’s compassion even for the defiled

Contemporary Jewish Practice #

  • After suicide bombings, Jews collect all body parts to maintain ritual integrity
  • Wear protective coverings not only for sanitation but for ritual purity reasons
  • Demonstrates continuity of purity concern even in modern context

Post-Partum Purification #

  • In 1980s Catholic tradition (especially Maronite), women underwent four-day bathing period after childbirth
  • Mother would come to church for special blessing of child (particularly firstborn)
  • This was the “Purification of Mary” in the Roman ritual
  • Families sometimes brought children specifically to monastery for blessing rather than parish

Handling Sacred Objects #

  • Old pastor objected to lipstick on communicants’ lips during Eucharist, as it soiled altar linens
  • Analogous to reverence principle: precious books should not be touched with soiled hands
  • Example: three editions of texts—pocketbook, desk copy, venerable copy (like Leonine edition of Thomas)
  • Shows how principle of reverence applies to both sacred and precious secular things

Superstitions in Mediterranean Cultures #

  • Lebanese Christians wear turquoise (not blue topaz) to ward off evil eye—superstitious though popular
  • Italian communities retain traditional healing and superstitious practices alongside modern medicine
  • Shows persistence of Old Law-type purity concerns in contemporary folk religion

Questions Addressed #

Why was purification necessary if creation is good? #

  • Purifications address corruption (death, disease, sin), not creation itself
  • They remove impediments to worship, teaching reverence through cleanliness requirements

How does the red heifer paradox work? #

  • Those performing the sacrifice become unclean, yet it purifies others
  • Priest who sprinkles becomes unclean; another must sprinkle him
  • Breaks infinite regress and signifies Christ’s passion (appearing as death/corruption) brings salvation

Why do inanimate things contract uncleanness? #

  • Whatever touches something unclean becomes unclean
  • Applies to houses, vestments, vessels
  • Corruption spreads through contact, requiring destruction (burning) of contaminated articles

Why do those performing sacred functions remain unclean? #

  • Those treating sacred things for others’ cleansing contract uncleanness themselves (Gregory)
  • Remains “until vespers” (usque vespers)—until end of present life
  • Signifies the cost of ministering to others’ spiritual needs

Notable Quotes #

“The body is more fit to be cast out than dung” — Heraclitus (cited by Berquist, discussing bodily uncleanness)

“Go forth from the middle of them and be separated and do not touch the unclean” — 2 Corinthians 6:17 (on avoiding consent to sin through contact)
