(Part 1 of 11) Introduction: Why, How, and What is the Study of God?

February 1, 2026 Preacher: Quinn Clement-Schlimm Series: Sunday School: Doctrine of God

Part 1 of 11 in the Doctrine of God series

Augustine: “In no other subject [doctrine of God] is error more dangerous, or inquiry more laborious, or the discovery of truth more profitable.”

  1. Why Study God?

    • Westminster Shorter Catechism Q1: “Man’s chief end is to glorify God and enjoy him forever.”
    • The Church’s Foundations: Scripture: the cognitive foundation & God: the ontological foundation
    • The Challenge of “Theistic Mutualism”: God in our own image
    • Key Point: What we believe about God shapes how we pray, suffer, repent and hope
  2. How Do We Study God? A. With humility and awe as his creatures i. Ad intra vs. Ad extra

    • Ad intra: God as He is in Himself (his attributes, triune)
    • Ad extra: God’s works in creation, providence, and redemption.

    ii. Archetypal vs. Ectypal theology

    • Archetypal theology: God’s (full) knowledge of God
    • Ectypal theology: Our (limited) creaturely knowledge of God

    iii. Limits of language

    • Univocal language: uses the same words in the same sense
      • E.g. I love my Aunt Stephanie and I love my Aunt Caroline
    • Equivocal language: uses the same words in entirely different senses
      • E.g. There’s a lot of bats at the baseball stadium. There’s also a lot of bats in this cave.
    • Analogical language: use the same words but in similar but distinct senses
      • E.g. This food is healthy. This economy is healthy.
    • When we speak of God, we are using analogical language.
      • E.g. God is our rock. The Lord make his face to shine upon you.
      • E.g. Luke 6:36: Be merciful as your Father is also merciful.

    B. With the Church

    • Scripture: Our final authority
    • The Dream Team (Appendix A): Our interpreters
    • Creeds: Our guardrails
  3. What is the Study of God? Theology Proper: the study of God himself; God’s attributes + triune existence Our Structure:

      1. God’s Attributes (also called perfections, virtues, properties, excellencies); both communicable and incommunicable attributes
      1. The Trinity
      1. Anthropology + Christology (Incarnation)

    Appendix A: Our Trinitarian Dream Team

    Theologian Work Difficulty Comments
    Athanasius On the Incarnation Easy A must read devotional classic
    Basil the Great   On the Holy Spirit   Moderate   Another classic 
     Gregory of Nazianzus  Theological Orations (Orations 27-31)  Challenging  
    Gregory of Nyssa  On Not Three Gods Challenging  
    Augustine of Hippo On the Trinity Challenging Profound and foundational but slow and abstract
    Anselm On the Trinity  Challenging  
    Thomas Aquinas Summa Theologica (qq. 27-43) Extremely Challenging Do you like pain? If yes, this book is for you.
    John Calvin Institutes of the Christian Religion Moderate A Protestant Classic
    John Owen Communion with God Moderate Warm devotional but intellectually demanding
    John Gill A Body of Doctrinal Divinity (Book 2) Challenging A great Baptist theologian
    Francis Turretin Institutes of Elenctic Theology (Topic 3) Extremely Challenging Height of Reformed Scholasticism
    Herman Bavinck Reformed Dogmatics (Vol 2) Challenging A great goal to work up towards

Foundational Modern Introductions

Beeke Reformed Systematic Theology (Vol 1) Foundational
