Yes, Ellen White clearly stated that the Holy Spirit is a person. She made several explicit statements about this:
**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" (
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" (
Ev 617.1).
"The Holy Spirit is a person, for He beareth witness with our spirits that we are the children of God" (
Ev 616.6).
**The Holy Spirit as the Third Person of the Godhead:**
Ellen White specifically referred to 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 also wrote about "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" (
Ev 615.1).
**Distinct Personality:**
"The Holy Spirit is the Comforter, in Christ's name. He personifies Christ, yet is a distinct personality" (Manuscript 93, 1893).
**Representative but Distinct:**
While Ellen White described the Holy Spirit as "Christ's representative, but divested of the personality of humanity, and independent thereof" (
DA 669.2), she maintained the personal distinction between Christ and the Holy Spirit throughout her writings.
Ellen White consistently portrayed the Holy Spirit as a divine person - the third member of the Godhead - with His own personality, distinct from but working in harmony with the Father and the Son.
