This document is a scholarly reply by William Hasker defending the historical development of the Trinity doctrine against Dale Tuggy’s critique, emphasizing biblical and theological evidence.

Disagreements on Definitions of Key Terms

  • The author criticizes Tuggy’s problematic definitions of ‘unitarian’ and ‘trinitarian,’ arguing they distort historical and theological understanding.
  • Tuggy’s broad ‘unitarian’ includes early theologians like Tertullian and Origen, despite their differing views, and his ‘trinitarian’ requires full ontological equality and identification of the Trinity with God, which the author finds overly restrictive.
  • The author emphasizes that these definitions misrepresent historical debates and the development of Christian doctrine.

Historical Development of Trinitarian Doctrine

  • The author presents a narrative that the doctrine of the Trinity developed gradually from the New Testament through early church councils, influenced by worship practices and theological reflection.
  • Tuggy’s account sees metaphysical speculation about Jesus as late and unitarian until the fourth century, with the Trinity as a late innovation enforced by imperial power.
  • The author argues that early Christians recognized Jesus’ divine status and that the development was a dynamic, ongoing process rather than a late invention.

Interpretation of Biblical Evidence

  • The author challenges Tuggy’s interpretation of five ‘facts’ used to support unitarianism, asserting they do not account for the full biblical evidence supporting trinitarian belief.
  • He argues that references to Jesus as ‘God,’ worship practices, and divine attributes are consistent with early recognition of Jesus’ divine nature.
  • The author advocates for understanding divine revelation as a gradual process of spiritual and intellectual discovery, rather than confusion or misinterpretation by early Christians.

The Concept of Divine Attributes and Monotheism

  • Tuggy claims that attributing divine properties to each person implies multiple gods, conflicting with monotheism.
  • The author counters that Christian theology avoids calling each person ‘a god’ to prevent tritheism and that divine essence is better understood as shared by persons, not as separate gods.
  • He criticizes Tuggy’s analytic approach as question-begging and emphasizes the importance of theological language that aligns with biblical and doctrinal contexts.

Biblical Worship and Jesus’ Divinity

  • Tuggy questions whether worship of Jesus indicates divinity, presuming a human-only view of Jesus.
  • The author argues that worship practices and titles like ‘God’ used for Jesus are powerful evidence of his divine status recognized early in Christianity.
  • He suggests that divine worship of Jesus reflects an early acknowledgment of his divine nature, consistent with the development of trinitarian doctrine.

Interpretation of Biblical Texts on Jesus’ Divinity

  • The text discusses how certain New Testament passages, such as John 10:35–36 and John 5:18, are used to argue Jesus’ divine status.
  • It emphasizes that Jesus’ opponents recognized his claims as making himself equal to God, which challenges unitarian interpretations.
  • The author critiques alternative readings that deny Jesus’ divine nature, asserting that the texts imply a divine ontological status for Jesus.

Challenges to Unitarian Exegesis of Key Passages

  • The author critiques Dale Tuggy’s interpretations of Philippians 2:5–11 and John 1:1–18, arguing they distort the texts’ traditional understanding.
  • Tuggy’s view reduces “form of God” and “equality with God” to moral character, which the author finds implausible.
  • The author defends the traditional view that these passages affirm Jesus’ pre-existence and divine nature, contrasting Tuggy’s identity-based interpretations.

Theological and Historical Context of Unitarianism

  • Unitarianism has historically struggled to gain acceptance within Christianity, often suppressed or marginalized.
  • The author notes that liberal Protestantism has been more receptive to unitarian ideas than traditional movements.
  • The limited success of unitarianism is attributed to its lack of spiritual appeal and the divine providence that favors mainstream Trinitarian doctrine.

Implications for Christian Doctrine and Divine Providence

  • The author suggests divine wisdom may have restrained the development of unitarian views to preserve monotheism.
  • He argues that long-held errors in theology can be corrected through divine intervention, which has not yet favored unitarianism.
  • The text emphasizes that most Christians continue to worship the Trinity, reflecting historical doctrinal development.
