Foundations of Christian Ethics – Comprehensive Study Notes

Triple Foundations of Christian Ethics

  • Discipline draws from three converging wells:
    • Greek philosophy ➔ provides rational, teleological & virtue-based frameworks
    • Hebrew–Christian Scriptures ➔ reveal God’s covenantal, historical & moral will
    • Christian theology ➔ synthesises revelation with reason, shaping distinctive Christian moral reflection
  • Together these strands establish the three-fold foundation on which modern Christian Ethics is taught & practised.

Philosophical Ethics (Greek Lineage)

  • Core presupposition: human beings possess a unique rational capacity able to govern emotions & appetites.
  • Ethical method is teleological – every act seeks a specific telos (end/purpose).
  • Ultimate end (summum bonum) = Eudaimonia (happiness, well-being, pleasure).
  • Happiness secured through cultivation of cardinal virtues: wisdom, moderation, courage & justice.

Platonism (Plato)

  • Happiness = harmonious, well-ordered personality; reason rules emotions & appetites.
  • Wisdom = highest virtue; crown of moral life & integrator of all other virtues.
  • Introduces eros – mutual, intellectual love that propels soul toward the Good.
  • Practical implication: ethical life ≈ quest for inner harmony using rational insight.
  • Connection to Christian thought: anticipates Augustine’s ordered love & the notion that dis-ordered desires produce sin.

Aristotelianism (Aristotle)

  • Eudaimonia = “activity of the soul in accordance with reason.”
  • Good life achieved when one’s actions express natural capacities & energies.
  • Key virtue: moderation (temperance) ➔ the “golden mean.”
  • Unhappiness arises when we act against our nature or capacities.
  • Ethical formula:
    Happiness \Rightarrow \text{Harmony with human nature} + \text{Moderate living}
  • Influence on Aquinas: natural law, virtue taxonomy & nature/grace dialectic.

Epicureanism / Hedonism (Epicurus)

  • Reality governed by two experiential poles: pleasure vs. pain.
  • Pleasure = "absence of bodily pain & mental turmoil" (ataraxia).
  • Rational calculation (hedonic calculus) guides choices.
  • Emphasises egoistic pursuit; later followers drift to crude sensualism.
  • Ethical yardstick:
    Good \equiv \text{What increases pleasure}\;\;(\alpha\;\Omega)
  • Contrast with Christian agapē: self-giving vs. self-serving pleasure.

Stoicism (Zeno & Epictetus)

  • Virtue = supreme good; all virtues inter-dependent.
  • Signature virtue: courage – inner resolve to align with universal Reason (Logos).
  • Motto: “Live consistently with nature.”
    • Conform human will to the rational, benevolent order of the cosmos.
  • End state: apatheia / euthymia – spiritual peace when soul mirrors divine rationality.
  • Ethical portrait: autonomous, uniform, benevolent character akin to God.
  • Seeds of Christian ideas: Logos theology (John 1), moral fortitude amidst persecution.

Transitional Figure – Augustine of Hippo

  • Bridges classical philosophy & medieval theology.
  • Integrates Neoplatonism with biblical narrative of creation-fall-redemption.
  • Key emphases:
    • History has a linear plot; God directs its beginning & culmination.
    • Salvation = synergy: grace initiates, human will cooperates.
    • Quest for truth fuels his conversion; sees God as the highest Beauty & Good.
  • Legacy: father of medieval Catholicism & fountainhead for Reformation soteriology.

Medieval Scholasticism – Thomas Aquinas

  • Apex of scholastic method; harmonises Aristotle with Christian doctrine.
  • Epistemology:
    • Senses provide raw data; reason abstracts universal truths.
    • Faith supplements reason; grasps revealed truths inaccessible to natural intellect.
  • Anthropology: human = natural & supernatural creature.
  • Ultimate happiness = beatific vision (contemplating God).
  • Strong doctrine of prevenient grace: enables repentance, new birth, good works.

Modern Ethical Systems Influencing Christian Discourse

Utilitarianism (Bentham & Mill)

  • Principle: “Greatest pleasure for the greatest number.”
  • Moves from egoism to collective hedonism.
  • Recognises qualitative hierarchy of pleasures – mental > animal.
  • Formula (Mill’s refinement):
    Good\;Act \Rightarrow \max{population} \sum Pleasure{quality,quantity}
  • Ethical tension: communal calculation vs. inherent dignity of the individual (Christian personalism).

Kantianism – Ethics of Duty

  • Sole unconditional good = goodwill (autonomous moral intention).
  • Categorical imperative – unconditional moral law:
    1. “Act as if the maxim of your action were to become a universal law of nature.”
    2. “Act only according to that maxim which you can at the same time will to be universal.”
  • Truth-telling example: lying fails universalizability test.
  • Resonates with Christian respect for universality of moral law (e.g., Golden Rule) yet rooted in pure reason, not revelation.

Existentialism (Kierkegaard, Sartre, Bultmann)

  • Existence precedes essence – humans craft their own meaning.
  • Radical freedom ⇒ anguish/dread but also authentic responsibility.
  • Good act = one performed in good faith, granting meaning now.
  • Ethical vision: mutual openness, treating neighbor as a person (I–Thou) & openness to God.
  • Christian adaptation: authenticity before God; Bultmann’s demythologizing of New Testament calls for existential decision.

Social-Adjustment / Pragmatism (John Dewey)

  • Rejects fixed absolutes; morality = dynamic social experiment.
  • Good conduct = successful adjustment within democratic society.
  • Values always provisional; revised through communal problem-solving.
  • Contrasts with immutable divine commands but shares theme of ongoing discernment (Acts 15 council model).

Christian Attitudes Toward Philosophical Ethics

  • Incorporation without discrimination
    • Risk: dilutes Christian distinctiveness; can yield mere “coalition ethics.”
  • Total rejection (e.g., Tertullian: “What has Athens to do with Jerusalem?”)
    • Fear of non-biblical foundations; may impoverish rational clarity.
  • Sympathetic yet critical appropriation
    • Recognises truth as God’s common grace; philosophical insights become servants to revealed morality.
    • Aligns with historical practice (Paul at Mars Hill, Augustine, Aquinas).

Integrative Takeaways & Exam Pointers

  • Trace how each school defines the summum bonum:
    • Plato: harmonious soul
    • Aristotle: activity according to reason (moderation)
    • Epicurus: pleasure (absence of pain)
    • Stoics: virtue aligning with cosmic reason
    • Augustine: ordered love of God
    • Aquinas: beatific vision through grace
    • Utilitarians: maximal collective pleasure
    • Kant: goodwill / universal law
    • Existentialists: authentic self-chosen meaning
    • Dewey: adaptive social function
  • Observe shifts from egoistic → altruistic → deontological → existential → pragmatic frameworks.
  • Relate to biblical teachings:
    • Virtue lists (Gal 5:22-23) mirror Greek virtues.
    • Beatitudes (Mt 5) invert pleasure-centric ethics.
    • Love-command integrates duty (Kant) with teleology (Aristotle) & relational authenticity (Kierkegaard).
  • Ethical implications:
    • Role of grace (Augustine/Aquinas) vs. autonomous reason (Kant/Stoics).
    • Community calculus (Utilitarianism/Dewey) vs. individual conscience (Existentialism).
  • Practical exam tip: be able to compare & critique each philosophy from a Christian standpoint, noting both appropriation and tension.
