By the Trinity is meant the unity of three persons in one Godhead; Father, Son, and Holy Spirit.
Representing God as one, the Scriptures also ascribe divinity to Father, Son and Holy Spirit.
Course of the Argument by H. B. Smith
a. God is one. Unity is ascribed to God.
b. The Father is divine a distinct person.
c. The Son is divine a distinct person.
d. The Holy Spirit is divine a distinct person.
e. The Father, Son, and Holy Spirit are classed together, separately from all other beings.
(See passages cited under Attributes, Unity.)
b. The Father is divine and a distinct person. The Word "Father" is used in the Scriptures in a two-fold sense in relation to the Godhead sometimes as equivalent to God, sometimes to the first person of the Trinity.

Result of the Biblical evidence in respect to the divinity of the Father, the Son, and the Holy Spirit.
1. That the Father, Son, and Holy Spirit are personally distinguished from each other. There is recognized throughout a personal relation of the Father and Son to each other. So of the Holy Spirit to both.
2. They each have divine names and attributes.
