The Father, Son, and Holy Spirit are distinct persons
The Bible says that the Father is the “one God”, (1 Corinthians 8.6) not “one distinct person of God”. That’s a later formulation that tries to obscure the fact the Trinity contradicts what the Bible says. The Bible doesn’t say anything about God consisting of different “persons”. In fact it assumes and sometimes explicitly states the opposite.
Galatians 3.20 But a go-between is not needed when only one person is involved; and God is one.
