Romans 8:16 the spirit ITSELF bears witness. Not the spirit himself. Not a separate person but the spirit that is God. John 16:18 he will reprove the world. He is God not a separate spirit. I Cor 12:11 the spirit divides to every man. The spirit that is God. No need for a separate person. Mat 28:19 Baptize in the name of the Holy Spirit. When the police arrest someone they arrest in the name of the law. Which means by the power or authority of the law. A person is baptized by the power or authority of God. No need for a thirg person spirit.Luke 3:22 the spirit descended like a dove. The spirit of God and some separate person. God is a spirit. Wht can't that spirit descend like a dove? Sorry but none of these verses prove that the spirit is a distinct person. They refer to the one spirit that is God and since only God is holy that is the one and only Holy Spirit.The Spirit is referred to as a distinct person, Romans 8:16, John 16:8, 1 Corinthians 12:11, Matthew 28:19, Luke 3:22.
