Date: March 10, 2026
Host: Kevin DeYoung (Crossway)

Overview

In this episode of Doctrine Matters, Kevin DeYoung dives deep into a pivotal and often contentious point in Trinitarian theology: the meaning and implications of the filioque clause. DeYoung unpacks its historical background, the theological debates between the Eastern and Western Church, and its enduring significance for Christians today. He also briefly explores two other important Trinitarian terms—perichoresis and taxis—offering listeners a clearer grasp of complex doctrines that shape Christian belief.

Key Discussion Points & Insights

1. The Trinity as a Central and Mysterious Doctrine

• [00:20] DeYoung frames the Trinity as one of the "most difficult doctrines" of Christian faith, referencing Francis Turretin's opinion and highlighting the necessity and value of precise theological vocabulary to express profound mysteries.
• Quote (DeYoung, 01:09):

  "A mystery is something that there are elements to it that belong to God... a mystery does not mean irrationality, but rather things that, because we're not God, we can't fully comprehend."

2. Defining "Filioque"

• [02:13] The term filioque is explained (“Latin for 'and the Son'”), referring to the clause in the Nicene Creed stating the Holy Spirit "proceeds from the Father and the Son."
• [02:55] Filioque became one of the main points of contention leading to the Great Schism between the Eastern and Western Church.
  • The Western Church added the phrase, likely without intending to innovate, whereas the Eastern Church objected both theologically and procedurally to changes in the Creed.

3. Historical and Theological Background

• [03:44]
  • The Nicene Creed was established in 325 AD, updated at Constantinople in 381 AD.
  • The filioque clause was introduced "a couple hundred years later," and its inclusion intersected with larger disputes about authority and theological precision.
• Eastern Church concern: Undermines unique authority of the Father and introduces possible confusion in Trinitarian relations.
• Western Church concern: Defending the full deity of the Son, especially in response to Arianism.

4. Theological Reasoning for and Against Filioque

• Western Arguments for Inclusion:

  1. Scriptural Reflection
     • John 16:7—the Spirit is sent by both Father and Son.
     • The mission of the Spirit in time reflects its “eternal procession.”
     • Quote (DeYoung, 07:20):

       "When we talk about proceeds from the Father and the Son, we are talking about eternally... the godness of the Spirit proceeds from the Father and the Son."

  2. Spirit of Christ
     • The Holy Spirit is often called “the Spirit of Christ.”
     • If the Spirit is “of Christ,” then not just temporal but eternal origin from the Son is implied.
  3. Glorification & Communication
     • The Spirit glorifies the Son as the Son glorifies the Father; thus, origin reflects this relational dynamic (not creation, but eternal communication).
  4. Christ Breathes Out the Spirit
     • Christ's breathing the Spirit on disciples (John 20:22) points to his role in the Spirit’s procession.

• Eastern Objections:

  • John 15:26: The Spirit "proceeds from the Father" (does not explicitly add “and the Son”).
  • Concern about implying two “sources” or “heads” within the Trinity.

• Doctrinal Nuance:

  • The Spirit does not proceed from two separate sources, or as if the Father passes the Spirit to the Son and then the Son passes it on.
  • The concept of "proceeds from the Father through the Son" was suggested as a possible common ground.

5. Why Filioque Matters

• [10:46] It connects the theology of Word and Spirit, ensuring that worship and understanding are anchored in Christ and the triune God.
• Quote (DeYoung, 11:20):

  "It does tell us something. That the Spirit is the Spirit of Christ. And that means our theology is according to the Word and our worship by the Spirit are always connected."

6. Additional Trinitarian Terms

a) Perichoresis (Mutual Indwelling)

• [12:00]
  • Perichoresis (Greek), or circumincession/circulatio (Latin) refers to the mutual indwelling of Father, Son, and Holy Spirit.
  • Not three entities dancing together, but three persons fully inhabiting one another without blending or confusion.
  • Quote (DeYoung quoting Augustine, 15:35):

    "Each are in each, and all in each, and each in all, and all are one."

  • Clarification: Against common misunderstandings, perichoresis is not about a social dance but about the co-inherence of the divine persons.

b) Taxis (Order within the Trinity)

• [16:50]
  • Taxis means “order”; refers to the relational order of Father – Son – Spirit.
  • Not a hierarchy or ontological subordination, but an order of relations and operations both internally (ad intra) and externally (ad extra).
  • The Father is unbegotten, the Son begotten, the Spirit proceeds.
  • Differentiation is by operation and relation, not by rank or divinity.
  • Quote (DeYoung, 19:50):

    "We can speak of an order so long as we understand... we are talking about Christ's mediatorial office and his earthly mission, not about His Divine Person being inferior or subjugated to the Father."
