Umm, yes the Holy Spirit is a person, equal to and one with Jesus, who is a person, and God the Father, who is a person. All are one in Essence, but also "God in three persons." (as the hymn, "Holy, holy, holy" says).
The whole doctrine of the trinity is that God is one, in 3 persons. (Not human persons, yes, except for Jesus, but "persons" none-the-less.) The very concept of personhood is derived from the Christian understanding of the 3 persons of the holy trinity, God.
This is basic Christian orthodoxy, which all Christian groups have accepted since AD 381.
If you don't accept it, you're simply not an orthodox Christian.
No, Christianity has accepted that the Father, Son, and Holy Ghost are to be called the “Trinity.”
The idea of God and the Holy Ghost being people is a much newer invention.
Neither calling them “people” or the “Trinity” are stated as such in anyone’s Bible translation.
