History of Philosophy Without Any Gaps

Episode 102 – Please Accept Our Apologies: The Greek Church Fathers

Host: Peter Adamson
Date: November 11, 2012

Main Theme & Purpose

This episode explores the emergence and thought of the Greek Church Fathers—primarily Irenaeus, Clement of Alexandria, and Justin Martyr—who helped define Christian orthodoxy in the 2nd and 3rd centuries. Peter Adamson delves into their philosophical responses to Gnosticism, their attitudes toward pagan philosophy, and their pivotal role as early Christian apologists. The episode highlights the dynamic interaction between faith, reason, and philosophy in the formative stages of Christian intellectual history.

Key Discussion Points & Insights

1. The Great Pumpkin, Gnosticism, and Philosophical Satire

• [00:11–04:10]

  • Adamson opens with a humorous analogy: comparing Linus’s faith in the Great Pumpkin (from Peanuts) to religious belief, referencing Alvin Plantinga’s philosophy, and Seneca’s mockery of deification ("Apokolocentosis" or "pumpkinification") to set the tone.
  • Uses these references to introduce the idea of belief, irrationality, and satirical critique, leading into how early Church Fathers opposed Gnostic beliefs.

  “Pumpkinology, then, is different from religion, albeit equally controversial.” (A, 02:10)

2. Irenaeus and the Critique of Gnosticism

• [04:11–13:00]

  • Irenaeus (late 2nd century) combats Gnostic cosmology, which posits a supreme God and lower divinities (Silence, Unity, Truth, etc.), mocking their multiplicity by suggesting they might as well worship a “divinity called Colokunthe—the Greek word for pumpkin.”
  • Gnostics’ elitism and disdain for the material world are perceived as threats to Christian doctrine; Irenaeus accuses them of immoral behavior, but Adamson argues the real fear was that their ideas were attractive and philosophically sophisticated.
  • Irenaeus uses philosophical argument against Gnostic dualism, asserting God’s absolute supremacy and unity, and denying that ignorance or evil could originate from God.
  • Critiques Gnostic appropriation of Greek philosophy, likening their doctrines to garments sewn from old rags of Hellenic ideas.

  "Irenaeus does not just rename the Gnostics’ principles after vegetables. He hopes that by rooting out their heresy, he will plant the seeds of truth in his readers’ minds." (A, 09:40)

3. Irenaeus’ Limited Optimism About Human Knowledge

• [13:01–15:30]

  • Irenaeus asserts that human knowledge is finite; some divine mysteries are simply beyond our grasp and should be accepted as such.
  • Contrasts with the Stoics and Gnostics, who believe perfect knowledge is attainable.

  “Irenaeus denies that men can know everything and gives examples of questions that lie beyond our ken... At a more exalted level, how can humans know what God was doing before he created the world?” (A, 14:10)

4. Clement of Alexandria: Philosophy as a ‘Faithful Friend’ to Christianity

• [15:31–25:00]

  • Clement, teaching in cosmopolitan Alexandria, seeks to integrate Hellenic philosophy into Christian pedagogy.
  • Philosophical truths (especially from Plato) are of divine origin—God first gave wisdom to Moses, then pagans borrowed from it.
  • Describes philosophy as preparatory to faith, extracting kernels of truth from pagan thought.
  • Notably, Clement redefines “pistis” (faith) as conviction rooted in understanding—applicable to both philosophy and religion.

  “Just as a coin retains its value no matter who handles it, so truth can be used to procure happiness, even if it is unearthed in pagan soil.” (A, 20:00)

  • Clement argues faith involves the will and confidence, aligns with Stoic ideas about assent, and reclaims the term “gnosis” for true Christian knowledge, distancing himself from Gnostic elitism.

  “Rather, pistis is distinctive because of one's level of commitment. When we have faith, we believe with confidence, even certainty, because what we believe has become evident to us, as he puts it.” (A, 23:00)

5. Clement’s Approach to Scripture and Allegory

• Clement models his allegorical reading of Scripture on Philo of Alexandria, not the Gnostics; he aims to demonstrate that orthodoxy can match the intellectual rigor of Gnostic or pagan philosophy.

6. Justin Martyr and Judaism vs. Christianity

• [25:01–29:40]

  • Justin, another apologist, stages a Platonic-style dialogue ("Dialogue with Trypho") presenting Christianity as “the true philosophy.”
  • Defends Christian faith with philosophical arguments and biblical exegesis, though sometimes betrays hostility toward Judaism.

  "Justin shares with Clement the idea that genuine philosophy is whatever is true, and therefore goes so far as to claim that Christianity itself is the true philosophy from a philosophical point of view." (A, 27:10)

  • Raises philosophical topics such as the nature of the soul and free will, arguing eternal life is a divine gift rather than intrinsic to the soul.

7. The Problem of Evil and Free Will

• [29:41–35:30]

  • Irenaeus addresses the classic question: if God is all-good and all-powerful, why evil and suffering?
  • He suggests souls must develop and perfect themselves through suffering and freedom—a view diverging from later Augustinian doctrines of original sin.

  “We should thank him for calling us to perfect ourselves and giving us commands we can follow along the way.” (A, 34:20)

  • Adamson notes this as a road “Christianity could have taken, but did not, at least not in the long run.”

Notable Quotes & Memorable Moments

• On irrational belief:

  “Couldn’t someone like Linus rationally believe in the existence of the Great Pumpkin without giving any good reason for that belief?” (A, 01:30)

• On refuting Gnosticism:

  “For Irenaeus, the vine of heresy is rooted in pagan philosophy. He is happy to use philosophical premises in his invective against the Gnostics.” (A, 10:30)

• On the value of pagan philosophy to Christians:

  “He [Clement] provides a detailed chronology to show that Moses lived many generations before even the earliest Hellenic philosophers... lending historical plausibility to his claim that Plato’s political ideas... derive ultimately from the Old Testament.” (A, 22:10)

• On defining faith:

  “When we have faith, we believe with confidence, even certainty, because what we believe has become evident to us.” (A, 23:55)
