Our God is One, but manifested in three persons • the Father, the Son, and the Holy Spirit. (Philippians 2:6; John 14:21-26)

God the Father is greater than all • the Source of the Word (Logos) and the Begetter. (John 14:28; John 16:28; John 1:14)

The Son is the Word flesh-covered, the One Begotten, and has existed with the Father from the beginning. (John 1:14; John 1:18; John 1:1)

The Holy Spirit , Who is eternal, proceeds forth from both the Father and the Son.
(John 15:26)
