Fourthly. These cautions being premised, I say that we are distinctly to worship the Holy Ghost. As it is in the case of faith in respect of the Father and the Son, John xiv. 1, “Believe in God, believe also in me,” — this extends itself no less to the Holy Ghost. Christ called the disciples for the acting of faith on him, he being upon the accomplishment of the great work of his mediation; and the Holy Ghost, now carrying on the work of his delegation, requireth the same. And to the same purpose are their distinct operations mentioned: “My Father worketh hitherto, and I work.” Now, as the formal reason of the worship of the Son is not his mediation, but his being God (his mediation being a powerful motive thereto), so the formal reason of our worshipping the Holy Ghost is not his being our comforter, but his being God; yet his being our comforter is a powerful motive thereunto.
