Is the Holy Spirit a what or who? Well, we have good news, he's a who. Usually, it's kind of hard to keep this straight because whenever we use the word spirit, we think of a what, a thing. So we say: I've got school spirit or something like that. Well, that's a thing. It's not necessarily an object. But, it's still a thing, and usually when you say you’ve got spirit or you’re spiritual, it means something you can feel like an emotion. But, here, at Pentecost, the Holy Spirit really is a person and we know that because of the way that the Holy Spirit has been given to us, which happens first in baptism: I baptize you in the Name of the Father, Son, and Holy Spirit.
