One God · three Persons
Classical Protestant teaching rejects modalism and tritheism and confesses one divine essence in three Persons.
Why it matters
This branch belongs to Triune God: 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.

Anonymous early Christian compiler is a source witness for this study: One baptismal name, three distinct Persons.
Having first said all these things, baptize into the name of the Father, and of the Son, and of the Holy Spirit, in living water. But if you have not living water, baptize into other water; and if you can not in cold, in warm. But if you have not either, pour out water thrice upon the head into the name of Father and Son and Holy Spirit.
Passage context and translation
The instruction names Father, Son, and Spirit and prefers living water; it then provides alternatives, including pouring when other water is unavailable. It is an early manual, not a census of all baptismal customs.
Before the excerpt
And concerning baptism, baptize this way:
After the excerpt
But before the baptism let the baptizer fast, and the baptized, and whatever others can
