Yes, Ellen White did explicitly state that the Holy Spirit is a person. Here are her clear statements on this topic:
**Direct Statements About the Holy Spirit's Personality:**
"We need to realize that the Holy Spirit, who is as much a person as God is a person, is walking through these grounds" (Manuscript 66, 1899,
Ev 616.5).
"The Holy Spirit has a personality, else He could not bear witness to our spirits and with our spirits that we are the children of God. He must also be a divine person, else He could not search out the secrets which lie hidden in the mind of God" (Manuscript 20, 1906,
Ev 617.1).
"The Holy Spirit is a person, for He beareth witness with our spirits that we are the children of God. When this witness is borne, it carries with it its own evidence" (
Ev 616.6).
**The Holy Spirit as the Third Person of the Godhead:**
Ellen White also identified the Holy Spirit as "the Third Person of the Godhead, who would come with no modified energy, but in the fullness of divine power" (
DA 671.2).
She further explained: "There are three living persons of the heavenly trio; in the name of these three great powers—the Father, the Son, and the Holy Spirit—those who receive Christ by living faith are baptized, and these powers will co-operate with the obedient subjects of heaven" (Special Testimonies, Series B, 7:62, 63,
Ev 615.1).
**Clarification About the Holy Spirit's Nature:**
While affirming the Holy Spirit's personality, Ellen White also clarified that "The Holy Spirit is Christ's representative, but divested of the personality of humanity, and independent thereof" (
DA 669.2). This means the Holy Spirit is a divine person but not limited by human physical form as Christ was during His earthly ministry.
Ellen White consistently presented the Holy Spirit as a divine person with personality, intelligence, and will - not merely an impersonal force or influence.
