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:
- 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
- By revelation of promises: The New Law shows what the Old Law merely promised in words
- 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:
- Physical location in place
- Part in whole
- 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:
- By expressing true understanding: Interior acts fall under the law’s prohibition (e.g., anger under homicide, lust under adultery)
- By ordering safer observance: The New Law requires abstaining from swearing except in necessity (vs. Old Law’s prohibition of perjury)
- 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:
- On exterior works: The Old Law is much heavier (many ceremonies); the New Law imposes few exterior works
- 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 #
- Exterior difficulty: The actual external work and its execution
- 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
