"Correct. There is only one spirit. However there is also only 3 spirits that are that one spirit"
How is this not a contradiction?
This is double talk. You don't even have scripture that says this. The scripture doesn't say these three spirits are one. It says these three .
The three are the Father, that's God,The Word, that's God , the holy ghost, that's God.
Now I said God three times but that doesn't mean three Gods. It's one God according to the scriptures, one spirit. So it's three times that one God is being referred to .
Some where along the way people come up with adding spirits like you did, adding persons, adding personalities, that's all made up.
