A person is a distinct individual having separate thoughts and actions that are uniquely his own.
The thoughts and actions of the Holy Spirit are not separate or uniquely His own, but are the thoughts and actions of the Father and Son.
“We know that we live in Him and He in us, because He has given us of His Spirit.” -- (1 John 4:13).
“For through Him [the Son] we both have access to the Father by one Spirit.” -- (Ephesians 2:18)
The thoughts and actions of the Holy Spirit in us are the thoughts and actions of the Father and Son in us.
How, then, is the Holy Spirit a third individual person if His thoughts and actions are not uniquely His own?
