This is what the Bible affirmed about
1. The nature of God:

1. God is one.
2. God the Father is God.
3. God the Son is God.
4. God the Holy Spirit is God.
5. God the Father, God the Son and God the Holy Spirit is distinct.

2. The nature of Christ:

1. Jesus is wholly God.
2. Jesus is wholly Man.
3. Jesus is one.
