I guess you can chew on this while you’re waiting for me, I mean him.
“The doctrine of the Trinity means that there is one God who eternally exists as three distinct Persons — the Father, Son, and Holy Spirit. Stated differently, God is one in essence and three in person. These definitions express three crucial truths: (1) the Father, Son, and Holy Spirit are distinct Persons, (2) each Person is fully God, (3) there is only one God.
The Father, Son, and Holy Spirit are distinct Persons. The Bible speaks of the Father as God (Philippians 1:2), Jesus as God (Titus 2:13), and the Holy Spirit as God (Acts 5:3–4). Are these just three different ways of looking at God, or simply ways of referring to three different roles that God plays? The answer must be no, because the Bible also indicates that the Father, Son, and Holy Spirit are distinct Persons.
For example, since the Father sent the Son into the world (John 3:16), he cannot be the same person as the Son. Likewise, after the Son returned to the Father (John 16:10), the Father and the Son sent the Holy Spirit into the world (John 14:26; Acts 2:33). Therefore, the Holy Spirit must be distinct from the Father and the Son.
In the baptism of Jesus, we see the Father speaking from heaven and the Spirit descending from heaven in the form of a dove as Jesus comes out of the water (Mark 1:10–11). John 1:1 affirms that Jesus is God and, at the same time, that he was “with God,” thereby indicating that Jesus is a distinct Person from God the Father (see also John 1:18). And in John 16:13–15, we see that although there is a close unity between the three persons, the Holy Spirit is also distinct from the Father and the Son.
The fact that the Father, Son, and Holy Spirit are distinct Persons means, in other words, that the Father is not the Son, the Son is not the Holy Spirit, and the Holy Spirit is not the Father. Jesus is God, but he is not the Father or the Holy Spirit. The Holy Spirit is God, but he is not the Son or the Father. They are different Persons, not three different ways of looking at God.”
