Three Persons
The Persons are really distinct by relations of origin and wholly possess the one divine nature.
Why it matters
This branch belongs to Triune God: The Latin Filioque is read as safeguarding the communion of Father and Son without making two causes of the Spirit; Eastern Catholic expression has its own legitimate idiom.
Historical context
The Catholic account receives Nicaea and Constantinople and develops Latin reflection on relations, procession, and one divine essence.
Tradition note
This is a Catholic introduction. Latin and Eastern Catholic churches share communion while differing in liturgical and theological expression.

Primary sources

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
