25 questions.
Read in order, follow a theme, or begin with the difficulty that matters most to you. Each question includes the full argument, an objection and response, and its sources.
Part 01
Source and divine perfection
What simplicity affirms, how its arguments work, and why fullness requires positive warrant.
- Question 01. What does Catholic faith affirm about simplicity, and what remains a philosophical explanation?A Catholic philosophy of simplicity receives the Church's confession while making its own arguments answerable to reason.
- Question 02. How can divine simplicity be reconciled with Scripture’s descriptions of God grieving, becoming angry, relenting, and answering prayer?Biblical speech reveals God's living goodness through real covenant history, without making creatures the source of his knowledge, love, or perfection.
- Question 03. Why affirm one universal underived source rather than a brute order or several ultimate sources?The ascent from received actuality to one source requires distinct arguments about dependence, scope, and uniqueness.
- Question 04. What does simplicity exclude, and how do its six accomplishments establish that exclusion?Six related inquiries examine whether anything more basic makes the divine source actual, one, existent, determinate, or perfect.
- Question 05. Why is the simple source positive plenitude rather than an unspecified absence of parts?The positive fullness of God requires warranted perfections as well as freedom from constitutive reception.
- Question 06. How can wisdom, goodness, and power differ in meaning while belonging to one divine actuality?Truthful differences of meaning need not divide the divine reality they describe.
Part 02
Participation and divine agency
Created reality, genuinely free action, knowledge, and providence.
- Question 07. How can creatures possess received being without becoming parts, modes, or appearances of God?Participation joins genuine creaturely possession to dependence upon a source that remains distinct from its gift.
- Question 08. What warrants saying that a creaturely manifestation truly discloses God?A created reality can truthfully disclose its source when the relation carrying that disclosure supports the claim made.
- Question 09. How can pure actuality include active power to create otherwise or create nothing?God's complete actuality excludes receptive deficiency while allowing the distinct question of freely exercised productive power.
- Question 10. What makes this creation a freely authored intention rather than an unexplained or random outcome?A possible world becomes a gift through intelligent authorship, not through possibility alone.
- Question 11. Why does necessary divine actuality not make this world necessary?The decisive question is whether God's necessary actuality necessarily entails this particular intention.
- Question 12. Does simplicity require the same intrinsic divine profile across alternative creations?Noncomposition, immutability, and sameness across alternative creations make different claims.
- Question 13. How does God know this actual world without receiving cognitive completion from it?Knowledge of possible worlds must be distinguished from knowledge of this actual creation.
- Question 14. How can divine sustenance support a creature's own action and freedom?A received power can be genuinely possessed and exercised without becoming independent of its source.
- Question 15. How can an eternal God genuinely act in time, answer prayer, and govern history?A timeless source need not make its effects timeless, but temporal knowledge and response require careful explanation.
Part 03
Trinity and personal communion
Real personal distinction within undivided deity.
- Question 16. How can three really distinct Persons subsist without composing or dividing God?Relations of origin distinguish the Persons without distributing divinity among them.
- Question 17. How should identity, predication, and counting be understood in Trinitarian claims?The logic of identity remains binding while theological language requires precise interpretation.
- Question 18. How does the Father's monarchy preserve the Son's and Spirit's full equality?Personal origin distinguishes Father, Son, and Spirit without assigning unequal measures of deity.
- Question 19. What does it mean to call God personal while confessing one divine intellect and will?The real distinction of the Persons does not divide divine knowledge or willing into three independent lives.
Part 04
Love and creaturely fulfillment
Christ, mercy, suffering, sacrament, grace, and the promise of communion.
- Question 20. How can impassible divine love be genuinely merciful and responsive?Mercy can belong fully to God without requiring that creaturely misery first supply a missing divine actuality.
- Question 21. How can the simple eternal Son become human and truly suffer?The Son's humanity is personally his without becoming a constituent that completes or changes the divine nature.
- Question 22. How do evil, suffering, and hiddenness challenge unreceived plenitude?An account of created goodness must explain defect and permission without making suffering an ingredient of divine perfection.
- Question 23. How can material sacraments mediate Christ without dividing God or reducing presence to symbolism?Created signs can truly mediate divine gifts, while the Eucharist requires its own account of substantial conversion and Christ's whole presence.
- Question 24. How do grace, beatific vision, and God all in all fulfill creatures without completing God?Consummation is creation's transformation in communion, not an achievement that supplies a missing perfection to God.
