Trinity
Classical Protestant confessions receive the Nicene doctrine of one God in three coequal Persons and treat Scripture as its final norm.
Why it matters
Most historic Protestant churches inherited the Western Filioque, but no Protestant magisterium settles every account of procession.
Historical context
Lutheran, Reformed, and Anglican confessions explicitly retain catholic Trinitarian teaching; later non-Nicene groups should not be treated as representative of classical Protestantism.
Tradition note
Protestantism has no single worldwide teaching office. This map distinguishes major confessional families and cannot represent every independent church.
Memory hook
Reformation did not mean rejection of Nicene Christianity.
Key points
- The Father is fully divine, unbegotten, and not a greater grade of God than Son or Spirit.
- The eternal Son is fully God, consubstantial with the Father, and mediator of creation and redemption.
- The Spirit is fully divine; many confessions retain procession from Father and Son while Protestant explanation varies.
- Classical Protestant teaching rejects modalism and tritheism and confesses one divine essence in three Persons.
Common questions
- Which creeds does this church confess?
- How does it understand the Filioque?
Practice and discussion
- Use the ecumenical creeds where the church receives them.
- Distinguish classical Protestantism from non-Trinitarian restorationist movements.

Primary sources
Basil writes in On the Holy Spirit:
Basil gathers scriptural divine names for the Holy Spirit, including the Spirit who proceeds from the Father.
It is called “Spirit of God,” “Spirit of truth which proceeds from the Father,” “right Spirit,” “a leading Spirit.”
Passage context and translation
Basil gathers the Spirit's scriptural names while explaining the Spirit's divine dignity and sanctifying work.
Before the excerpt
First of all we ask, who on hearing the titles of the Spirit is not lifted up in soul, who does not raise his conception to the supreme nature?
After the excerpt
Its proper and peculiar title is Holy Spirit; which is a name specially appropriate to everything that is incorporeal, purely immaterial, and indivisible.
