CTF 2025 - Session 2 - Divine Simplicity
Divine simplicity — the doctrine that God is without parts of any kind, physical or metaphysical — is the necessary precondition for God to be the absolute first cause of all things confessed in Romans 11:36. This lecture, drawn from 2LCF Chapter 2 Paragraph 1, works through the logic of composition and dependence to show that any being composed of parts is doubly dependent: upon those parts and upon whatever unifies them, and is therefore disqualified from being the uncreated Creator. Divine infinity is then treated as a corollary of simplicity: because God has no compositional structure of finitude, his being is actual, unbounded, and without lack, which is the only reliable ground for absolute trust and worship.
Divine Simplicity - Of God and the Holy Trinity (2LCF 2.1-3)
Divine simplicity — the classical doctrine that God has no parts, no composition whatsoever, and that all that is in God is God — is examined through its confessional, definitional, historical, and doctrinal dimensions. The 1689 London Baptist Confession's phrase 'without body, parts, or passions' serves as the entry point, with 'without parts' identified as the direct expression of divine simplicity. The doctrine is shown to be the ontological foundation for God's aseity, infinity, immutability, and the unity of his attributes, and is traced through an unbroken stream of witnesses from Irenaeus and Augustine through Aquinas, the Reformers, and the Reformed scholastics. Hearers are pressed to resist any conception of God as a composite being whose attributes are properties inhering in a subject, and to affirm instead that God is identical with his own essence, being, and every perfection predicated of him.
