I think a few witches blasphemed The Holy Spirit by calling him it or a demon"

A common mistake made with regard to the Holy Spirit is referring to the Spirit as "it," something most translations of the Bible are careful to avoid. The Holy Spirit is a person. He has the attributes of personhood, performs the actions of persons, and has personal relationships.

The Scripture: In Matthew 12:31-32, Jesus says that every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven [0.6.1. 0.6.3].
