Show me in the Scripture where Jesus plainly said that He was the Holy Spirit. You can't, because He never said it. I will answer a few of your comments to the best of my ability and direct you to some links. By keeping the Godhead as One Being, we do not minimize the Holy Spirit of God. This denotes personality.
Personification is a common feature of the ancient languages.
You can only lie to a person. God is pure or Holy Spirit. Therefore, to lie to the Holy Spirit is to lie to God is to lie to the Spirit of the Lord. Now, there are not three Spirits but One. If God has a Spirit, Jesus has a Spirit and Holy Spirit has a Spirit then this makes six, not three, gods.
