The Nicene Creed’s statement about the Holy Spirit has become a point of division between Eastern and Western Christians. English speakers may know the dispute by its Latin name, filioque: “and the Son.” Understanding the Greek verb helps us listen carefully, though the disagreement cannot be reduced to a vocabulary problem.
The Word
ἐκπορεύομαι (ekporeuomai) means to go out from or to proceed. In John 15:26, Jesus uses it of the Spirit’s relation to the Father.
The verb also has ordinary uses. Its presence in a sentence does not automatically turn that sentence into a statement about eternal relations within the Trinity.
Range of Meaning
Matthew 4:4 speaks of what comes from God’s mouth. Revelation 22:1 describes the river of the water of life flowing from the throne of God and the Lamb. John 15:26 speaks of the Spirit who goes out from the Father.
In later Greek theology, the corresponding language of procession acquired a precise use for the Spirit’s eternal origin from the Father. Latin procedere could carry a broader sense of coming forth. Differences in usage matter when comparing formulas, but they do not remove every doctrinal question.
Where You’ll Meet It
Jesus promises:
“When the Advocate comes, whom I will send you from the Father—the Spirit of truth who goes out from the Father—he will testify about me” (John 15:26, NET)
Keep both statements in view. Jesus will send the Spirit from the Father, and the Spirit goes out from the Father. The verse does not contain the creed’s later added words and the Son. Nor should the Son’s sending of the Spirit simply be ignored.
The immediate promise concerns the Spirit’s witness to Jesus. Discussion of eternal procession must remain attentive to that promise rather than treating the verse only as material for an argument.
What Confessional Lutherans Hear
Lutherans receive the Western form of the Nicene Creed, confessing the Spirit’s procession from the Father and the Son. This is the form included in the Book of Concord. It belongs with the confession that the Spirit is Lord and giver of life, worshiped and glorified with the Father and the Son.
The creed associated with Constantinople in 381 confessed procession from the Father without the Western addition. Eastern Christians object both to the addition’s authority and to what they understand it to imply about the Father’s unique place as the Spirit’s source. They do not thereby deny the Spirit’s deity.
Western teaching intends to confess the unity of Father and Son in the Spirit’s eternal procession, not two independent sources producing the Spirit. Eastern concern about origin and Western use of broader procession language need to be represented accurately before either position is assessed.
This history explains why merely supplying an English gloss cannot settle the controversy. There are questions of doctrine and of the church’s authority to alter a received creed. A faithful Lutheran account can state its confession clearly while allowing Eastern Christians to recognize their own concern in the description.
Where People Get It Wrong
The dispute is sometimes told as though one misunderstood word single-handedly divided the church. That is too simple. It is equally misleading to suggest that the Eastern position makes the Spirit less than God, or that the Western confession intends two unrelated causes of his existence.
So What
The Spirit promised by Christ bears witness to Christ. You do not need to master the history of the controversy before receiving that witness through the Word.
Confess the Spirit with the church’s seriousness and speak about other Christians with accuracy. The Spirit who brings you to Christ is not a lesser messenger. He is true God, giving the life and consolation Christ promises.
