Trinity
Christian teaching confesses one God in three distinct Persons: Father, Son, and Holy Spirit.
Why it matters
The Father's monarchy names relations of origin, not superiority; the Greek conciliar Creed says that the Spirit proceeds from the Father.
Historical context
The Cappadocian Fathers helped stabilize the language of one ousia and three hypostases; later Orthodox teaching receives that grammar within worship.
Tradition note
This is a Chalcedonian Eastern Orthodox introduction. Local usages vary among autocephalous churches.
Memory hook
One essence; three hypostases; the Father is source without being more divine.
Key points
- The unbegotten Father is the personal source of the Son and Spirit, never a higher grade of deity.
- The Son is eternally begotten, not made, and wholly shares the one divine essence.
- The Holy Spirit is fully divine and proceeds eternally from the Father in the Creed's wording.
- One undivided divine essence and three irreducible hypostases guard against both modalism and tritheism.
- God is truly known in revelation and communion yet remains beyond comprehension and creaturely definition.
Common questions
- How is the Father's monarchy different from subordination?
- Why does Orthodoxy retain the Creed without the Filioque?
Practice and discussion
- Pray the Nicene-Constantinopolitan Creed.
- Address prayer to the Father, through the Son, in the Holy Spirit.

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.
