Host: Bishop Robert Barron
Episode: WOF 485: “Ipsum Esse” & Catholic Social Teaching (Part 1)
Date: April 14, 2025

In this episode, listeners hear the first half of Bishop Robert Barron’s lecture delivered at Charles University in Prague. The focus is on St. Thomas Aquinas’s distinctive conception of God as ipsum esse—the sheer act of “to be”—and how this metaphysical insight grounds some of the principal themes of Catholic social teaching. Barron interweaves deep philosophical insights with contemporary implications, outlining why Aquinas’s theology remains vital for engaging issues of social order, law, and political life today.

Key Discussion Points and Insights

1. Thomistic Grounding of Catholic Social Teaching

• Catholic social teaching, as developed by Pope Leo XIII and successors, owes an enormous debt to Aquinas. (00:42)
• While Aquinas did not write a systematic political treatise (except perhaps De Regno), his synthesis of biblical, patristic, and classical wisdom formed a foundation for later Church teaching regarding property, the common good, just war, and more.
• Crucially, Barron suggests that these practical teachings are ultimately rooted in Aquinas’s metaphysics: “We know who we are and how we ought to behave at both the personal and societal level, precisely in the measure that we have an at least inchoate sense of who God is.” (02:09)
• Metaphysics precedes ethics: Understanding being itself (how things exist) shapes ethical and social principles.

2. Who God Is for Aquinas: Ipsum Esse

• Aquinas teaches that God is not one being among many, but being itself (ipsum esse). (03:10)
• Uses both via negativa (negative way)—saying what God is not (infinite, immutable, eternal)—and via positiva (positive way)—saying what God is (good, perfect, omniscient).
• The term “simple” encapsulates much: in God, essence and existence coincide; God is not defined by category or limitation. This connects the negative (undefinable) and positive (fullness of being) paths.
• Using Aquinas’s philosophical distinction:
  • Essence (quiditas): what something is (its “whatness”)—a principle of potentiality
  • Existence (esse): the act of being—an active principle
  • In creatures, these are distinct; in God, they are identical.

3. The Creation Metaphysics

• All things in which essence and existence are distinct depend absolutely on God—the pure act of being (“ipsum esse”).
• Creation is not a one-time event, but a continual act—“Creatio continua”—God sustains the universe at every moment. (08:50)
• Memorable metaphor:
  • Herbert McCabe, as quoted by Barron:

    “Not just like a sculptor who makes a statue and then leaves it alone, but rather like a singer who keeps her song in existence at all times.” (09:26)

4. God’s Transcendence and Immanence

• God is radically “other”—not competing for space or power with creation.
• Neither do they jostle with one another for dominance on the same ontological grid... (11:43)
• Biblical symbol:
  • The burning bush (Exodus) as an image of God’s intimate proximity not destroying or consuming what He is near to—anticipating the Incarnation.
• Avoiding Pantheism: Despite God’s immanence, Aquinas maintains the infinite ontological divide between Creator and creature:

  “Actus puris could never be confused or commingled with beings marked by potentiality.” (12:55)

• Result: This opens up a space for relative independence of creation—“God opens up a space that is proper to the finite order, allowing it its own integrity.” (13:22)

5. Creation as Peaceful Gift and Love

• Genesis stands out from other ancient creation myths: God creates through nonviolent speech, not conquest.
• Augustine’s musical metaphor:
  • Each creature is like a note in a divine melody; things endure only for a moment before giving way to the next (16:30).
  • All creatures are united at the depth of their being in God—“like islands in an archipelago, separate at the surface but joined at the depths.” (17:45)
• St. Francis’s “Brother Sun and Sister Moon”—not just poetry, but metaphysical truth.
• Creation is not perfect yet: God wills the world to evolve toward greater perfection, allowing free process and free will.
• God’s act of creation is utterly generous and without self-interest:

  “He can only will the good of the other, since what is other to him can be of no possible advantage to him.” (14:51)

• Irenaeus’s axiom: “The glory of God is a human being fully alive” (15:32)

6. Implications for Social and Political Order

• Thomistic metaphysics “clears out space for both nature and society.” The act of creation enables both material evolution and voluntary social evolution. (20:23)
• God is not a rival to human freedom or social agency.
• Illustration from 1 & 2 Samuel:
  • God moves history not by crude intervention, but on a qualitatively different dimension, allowing for both secondary causes and the openness of history. (21:11)
• Thomistic moral theory:
  • The will is always moved by values that appear to reason (e.g., preservation of existence, raising of children, pursuit of knowledge).
  • Freedom is not mere self-determination, but “a disciplining of desire so as to make the achievement of these goods first possible and then effortless.” (21:37)
  • Virtue is the result of habituation, informed by a hierarchy of objective values under God—the “supreme, noncompetitive good.”
• Social and Political Life:
  • Human communities form for pragmatic reasons, but ultimately exist for friendship, virtue, justice, peace, and worship of God. (22:19)
  • Law’s purpose is the common good:

    “The first principle in practical matters… is the last end, and the last end of human life is bliss or happiness. The law must needs regard principally the relationship to happiness. Moreover, since every part is ordained to the whole, and since one man is part of the perfect community, the law must needs regard properly the relationship to common happiness.” (23:40, quoting Aquinas)

  • Barron adds:

    “It’s a marvelously pre-modern understanding of law, it seems to me, not just a matter of protection of rights, but of orientation to the ultimate good.” (24:20)

Notable Quotes and Memorable Moments

• On the necessity of starting with metaphysics:

  “As always with Thomas Aquinas, metaphysics comes first and ethics follows accordingly.” (02:28)

• On God’s creative activity:

  “God sustaining the universe moment to moment, as the contemporary Thomist Herbert McCabe puts it: Not just like a sculptor who makes a statue and then leaves it alone, but rather like a singer who keeps her song in existence at all times.” (09:26)

• On God’s non-competitive otherness:

  “Instead, God, the true God, can come intimately close to a creature without compromising its integrity.” (11:49)

• On the purpose of creation:

  “To love is to will the good of the other. If this is the case, then the cause that is fully actualized… can direct his will ad extra only in a completely unselfinterested manner.” (14:45)

• On the unity of all creation:

  “Individual creatures are like islands in an archipelago, separate at the surface but joined at the depths.” (17:45)

• On law and the common good:

  “Law, rightly promulgated, leads to habituation, which leads to virtue, which leads finally to the attainment of a shared happiness or participation in the highest good.” (23:35)

Summary

Bishop Barron’s lecture masterfully demonstrates that understanding Aquinas’s concept of God as ipsum esse is not an abstract exercise, but crucial for grounding Catholic views on the human person, society, and politics. The continual, loving, and non-competitive act of creation roots the dignity and integrity of the human person and the material world, while providing the ultimate rationale for justice, virtue, and the common good. The law, for Aquinas (and for Barron), is more than the protection of rights—it is about orienting society toward its highest flourishing in God.

Listeners are left eager for Part 2, where Barron is sure to dig deeper into how these themes play out in specific political and social doctrines.
