I think post 169 should serve as an answer...thanks!
Blasphemy against the Son can be forgiven, but not against the Holy Spirit ... therefore the Son and the HS are distinct.
Done ... proof complete.
Are you really going to claim that the absence of the HS in a particular passage that has the Father and the Son means He is not a separate person?
It seems logically incoherant to claim a passage that excludes the HS demonstrates your position but passages that include Him are to be ignored or glossed over.
The baptism of Jesus and the baptismal formula in Matt 28 are your judges.
Perhaps your issue is not with the doctrine of the HS ... but with the inspiration of the scriptures.
