Of course, the Holy Ghost is the third person of the Holy Trinity. However, the Holy Ghost, like God the Father, has no human nature, He is purely "spiritual" (if that is the correct word). Only God the Son has both a human nature and a divine nature.
You will need to elaborate here.
The reason I posted this was because I just learned that it is Church doctrine that indeed the HS is a person. I think the teaching is important as it helps clarify the relationship between us and the Trinity. Maybe instead of trying to obtain something super-natural with the HS we should be speaking and respecting the HS in the same manner we do Jesus.
There are three persons in the Holy Trinity: God the Father, God the Son, and God the Holy Ghost. They each have a separate "person-hood," but there is only one God.
All three persons of the Holy Trinity are divine in nature (that part is obvious). But, only God the Son also human nature. That is a result of the Incarnation. So, while God the Father and God the Holy Ghost each have their own distinctive divine "person-hood," they do not have a human nature.
While both God the Father and God the Holy Ghost come into the material world, only God the Son took on a human nature when he came into the world.
If it helps, God the Father and God the Holy Ghost could be described as "Divine Persons," while God the Son can be described as a "Divine Person and a Human Person."
