Hebrews 1 speaks of the Supremacy of the Son.
Verse 8 says about the Son, "Your throne, O God, is forever and ever, and the scepter of your kingdom is a righteous scepter.
If we include the Holy Spirit, as we have to, the world concludes there are three gods in Christianity. There has to be, because Christians themselves say:
The Father is neither the Son nor the Spirit
The Son is neither the Father nor the Spirit
The Spirit is neither the Father nor the Son
Therefore the Father is one god, the Son is another god, and the Holy Spirit is another god.
This is heresy at it's worst.
