Not true of the Bible though. The Bible says it all.
Three persons "In the NAME of the Father, the Son AND The Holy Spirit" Matt 28
Singular, indicating one, not three. Again the verse says nothing about three separate persons.
"Another Comforter" - John 14... "HE the Spirit of Truth when HE comes HE will guide you into all truth". John 16.
"The Holy Spirit says..." Hebrews 3.
Look at the very next verse:
John 14:18 I will not leave you comfortless:
I will come to you.
And Jesus continued to say
20 At that day ye shall know that I am in my Father, and ye in me,
and I in you.
Who's that comforter? According to Jesus? Himself! Not a spirit that is distinct separate person.
Ellen White confirmed this
"Christ tells us that the Holy Spirit is the Comforter, and the Comforter is the Holy Ghost, “the Spirit of truth, which the Father shall send in My name.” “I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever; even the Spirit of truth; whom the world cannot receive, because it seeth Him not, neither knoweth Him: but ye know Him, for He dwelleth with you, and shall be in you” [
John 14:16, 17].
This refers to the omnipresence of the Spirit of Christ, called the Comforter. ...—Letter 7, 1891.{14MR 180.4}
Who did apostle Paul say is the holy spirit? The spirit of Christ!
Rom 8
8 So then they that are in the flesh cannot please God.
9
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
Gal 4
5 To redeem them that were under the law, that we might receive the adoption of sons.
6 And because ye are sons,
God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
Ellen White calls the Holy Spirit the "THIRD PERSON of the Godhead".
Triniterians like to quote from this one book Evangelism compiled and published in 1956 while ignoring everything else she wrote.
"The testimonies themselves will be the key that will explain the messages given, as scripture is explained by scripture.” {Selected Messages Book 1, p42
Do not take one verse out of context. Allow her own testimonies to explain themselves.
“The Spirit was given as a regenerating agency, and without this the sacrifice of Christ would have been of no avail. The power of evil had been strengthening for centuries, and the submission of man to this satanic captivity was amazing. Sin could be resisted and overcome only through the mighty agency of the third person of the Godhead, who would come with no modified energy, but in the fulness of divine power. It is the Spirit that makes effectual what has been wrought out by the world's Redeemer. It is by the Spirit that the heart is made pure. Through the Spirit the believer becomes a partaker of the divine nature.
Christ has given his Spirit as a divine power to overcome all hereditary and cultivated tendencies to evil, and to impress his own character upon the church.” {Review and Herald, May 19, 1904 par. 3}
“Christ tells us that the Holy Spirit is the Comforter, and the Comforter is the Holy Ghost, "the Spirit of truth, which the Father shall send in My name." …
This refers to the omnipresence of the Spirit of Christ, called the Comforter.” {Manuscript Releases Vol.14, p. 179}
“T
he divine Spirit that the world's Redeemer promised to send
is the presence and power of God.” {E. G. White, Signs of the Times, November 23, 1891}
“
There must be a power working from within, a new life from above, before men can be changed from sin to holiness.
That power is Christ. His grace alone can quicken the lifeless faculties of the soul, and attract it to God, to holiness.” {Steps to Christ, p. 18}
“
The Holy Spirit, which proceeds from the only begotten Son of God, binds the human agent, body, soul, and spirit, to the perfect, divine-human nature of Christ.” {E. G. White, Review and Herald, April 5, 1906 par. 16}
“Christ declared that after his ascension, he would send to his church, as his crowning gift,
the Comforter, who was to take his place.
This Comforter is the Holy Spirit,--the soul of his life, the efficacy of his church, the light and life of the world. With his Spirit Christ sends a reconciling influence and a power that takes away sin.” {E. G. White, Review and Herald, May 19, 1904 par. 1}
Allow EGW to explain herself, the holy spirit is the spirit of Christ and the power and presence of God, not a separate, distinct, co-equal, co-eternal third person.
Not sure why you are calling for Ellen White support here.
Because you quoted from DA. I believe Ellen White was a messenger of God and I take her testimonies as a whole, not just a quote here and there that fit my preconceived ideas.
