Lecture 283

283. The Fulfillment and Containment of Old Law in New Law

Summary
This lecture examines how the New Law fulfills the Old Law through the distinction between perfect and imperfect, exploring whether the New Law is contained in the Old and how Christ’s teaching perfects the precepts of the Law. Berquist analyzes three primary questions: whether the New Law fulfills the Old, whether the New Law is contained within the Old as a seed contains a tree, and how apparent contradictions between the laws are resolved through careful theological distinctions.

Main Topics #

The Fulfillment of Old Law by New Law #

  • The New Law fulfills the Old Law as perfect fulfills imperfect
  • Fulfillment occurs in three distinct ways:
    1. By justification through Christ’s passion: The Old Law promised justification but could not effect it; the New Law achieves this through Christ’s power
    2. By revelation of promises: The New Law shows what the Old Law merely promised in words
    3. By completion of figures: The New Law completes what the Old Law figured in its ceremonial precepts
  • Ceremonial precepts are not eliminated but fulfilled—their signification is completed
  • Moral precepts are deepened and internalized rather than contradicted

The New Law Contained in the Old Law #

  • The New Law is contained in the Old Law in potentia (in power), not in actu (in act)
  • Three senses of “in” are operative:
    1. Physical location in place
    2. Part in whole
    3. Genus containing species, cause containing effect
  • The relationship is analogous to:
    • A tree contained in a seed: fully present but requiring development
    • Fruit contained in the ear of grain: herb → ear → full fruit (progression from natural law through Mosaic law to Gospel)
  • All things to be believed in the New Testament are treated in the Old Testament implicitly under a figure rather than explicitly
  • The precepts of the New Law are greater in explicit manifestation but all are substantially contained in the Old Law

Christ’s Fulfillment Through Teaching and Deed #

  • By deed: Christ observed the legal observances of his time (circumcision, etc.), fulfilling them in act
  • By teaching: Christ fulfilled the precepts in three ways:
    1. By expressing true understanding: Interior acts fall under the law’s prohibition (e.g., anger under homicide, lust under adultery)
    2. By ordering safer observance: The New Law requires abstaining from swearing except in necessity (vs. Old Law’s prohibition of perjury)
    3. By adding counsels of perfection: Commands to go beyond precepts (e.g., selling all possessions)

The Apparent Burden of the New Law #

  • The New Law appears heavier because it prohibits interior motions of the soul
  • However, the actual difficulty is twofold:
    1. On exterior works: The Old Law is much heavier (many ceremonies); the New Law imposes few exterior works
    2. On interior acts: The New Law is heavier for those without virtue, but easier for those with virtue
  • The grace of the Holy Spirit makes observance easy and delightful for those who love God
  • Augustine’s principle: “My commands are not grave to the one who loves, but to the one not loving, they are grave”

Key Arguments #

The Objections Against Fulfillment #

  • Objection 1: The New Law is not totally fulfilling because the judicial and ceremonial precepts are not mentioned

    • Resolution: Ceremonial precepts are fulfilled through exclusion of observance; judicial precepts teach the intention of justice (not private revenge) which remains in the New Law
  • Objection 2: The New Law contains things not in the Old (e.g., faith in Trinity)

    • Resolution: These are contained implicitly in the Old Testament, not explicitly; all things to be believed are treated in the Old Testament “under a figure”
  • Objection 3: The New Law cannot be contained in the Old if having the Old means one has the New

    • Resolution: Something is contained in another in power (as effect in cause, genus in species) as well as in act; the greater is contained in the lesser in potentia

The Apparent Weight of the New Law #

  • Objection 1: The New Law prohibits interior acts (anger, lust) which the Old did not; therefore it is heavier
  • Objection 2: The Old Law promised prosperity; the New Law promises tribulation
  • Objection 3: The New Law makes additions to the Old Law’s precepts (e.g., oaths, divorce), making it more difficult

Against all: Christ says “My yoke is sweet and my burden is light” (Matthew 11:30)

Resolution: The distinction between exterior and interior difficulty is crucial. The New Law is lighter overall despite appearing heavier in interior acts.

Important Definitions #

Key Distinctions #

  • In actu (in act): Explicitly present and manifest
  • In potentia (in power): Present implicitly, requiring development
  • Substantia (substance): The essential meaning or content
  • Figura (figure): A figurative or shadowy representation
  • Precepts: Commands binding on all; the precepts of the natural law remain in the New Law

The Two-Fold Difficulty of Virtue #

  1. Exterior difficulty: The actual external work and its execution
  2. Interior difficulty: The internal act of will, emotion, and motive—doing something “promptly and with delight”

Examples & Illustrations #

The Seed and the Tree #

  • A tiny seed contains a great tree in power, not in act
  • If someone showed you an acorn and said a massive oak tree could grow from it, you’d rather take the acorn than wait for the full tree
  • The New Law is similarly contained in the Old Law as potential awaiting actualization

The Ear of Grain #

  • Chrysostom’s progression: First the herb (legi naturae—natural law), then the ear/spicae (Mosaic law), then the full fruit (Gospel)
  • Each stage develops what was present in potentia in the previous stage

Interior vs. Exterior Precepts #

  • Old Law: “You shall not commit adultery” (exterior act)
  • New Law: “You shall not desire your neighbor’s wife” (interior act)
  • Old Law: “You shall not kill” (exterior act)
  • New Law: “You shall not be angry with your brother” (interior act)
  • The New Law deepens the understanding of what the law truly prohibits

Virtue and Ease #

  • Aristotle teaches that the just man does just things easily and with pleasure
  • Doing such things without justice is valde difficile (very difficult)
  • A mother changes diapers with ease because of love for her child; for those without such love, it would be burdensome
  • Similarly, the precepts of the New Law are easy for those with charity and virtue

Notable Quotes #

“The new law is compared to the old as the perfect to the imperfect. But everything perfect fulfills that which is lacking in the imperfect.” — Thomas Aquinas (Berquist’s exposition)

“The new law is contained in the old as fruit in the ear of grain.” — Thomas Aquinas / Chrysostom (Berquist’s key illustration)

“My yoke is sweet and my burden is light.” — Christ in Matthew 11:30 (cited as resolution to the apparent weight of the New Law)

“My commands are not grave to the one who loves, but to the one not loving, they are grave.” — Augustine, cited by Aquinas and Berquist

“Come to me, all you who labor and are burdened.” / “My yoke is sweet and my burden is light.” — Matthew 11:28-30 (cited as authoritative against the claim that the New Law is heavier)

Questions Addressed #

Does the New Law Fulfill the Old Law? #

  • Answer: Yes, through justification, revelation of promises, and completion of figures
  • The Old Law promised what the New Law effects through Christ’s passion
  • Ceremonial precepts are fulfilled in their completion, not abolished
  • Moral precepts are deepened, not contradicted

Is the New Law Contained in the Old Law? #

  • Answer: Yes, in power (potentia), as a tree is contained in a seed and fruit in the ear of grain
  • All things to be believed are in the Old Testament implicitly under a figure
  • The precepts are greater in explicit manifestation but substantially contained in the Old Law
  • The greater can be contained in the lesser when understood in terms of potency

Is the New Law More Burdensome than the Old? #

  • Answer: No; it is lighter overall, though it appears heavier in interior prohibition
  • The Old Law is much heavier in exterior observances (many ceremonies)
  • The New Law is heavier for those without virtue, but easier for those with virtue and charity
  • Grace makes the precepts easy and delightful for those who love God
  • The difficulty lies not in the law itself but in the interior condition of the observer
