I don't think there is a scripture calling the Holy Spirit --Holy Mystery by Name ---
I think the only person I have heard that from is jimkenney12
My view
The Holy Spirit is a person ---the 3rd person of the triune God ------the Scripture reveals the Mystery OF the Holy Spirit who is a Person called the Spirit of Truth -----He is never referred to as the Holy Mystery for His Name in Scripture ==The Holy Spirit reveals the Mystery of the Scripture by and through enlightenment to the true Believer ------
