Though Ellen White never used the word "trinity" regarding the Godhead in her writings, preferring "Godhead," she believed there was a trinity of three eternal persons that made up the Godhead. On this page I share some of those quotes. There are many so the few that are here to begin with are a very limited sampling.—Dan
"Matthew 28:19 "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:"
"Man’s capabilities can multiply through the connection of human agencies with divine agencies. United with the heavenly powers, the human capabilities increase according to that faith that works by love and purifies, sanctifies, and ennobles the whole man. The heavenly powers have pledged themselves to minister to human agents to make the name of God and of Christ and of the Holy Spirit their living efficiency, working and energizing the sanctified man, to make this name above every other name. All the treasures of heaven are under obligation to do for man infinitely more than human beings can comprehend by multiplying threefold the human with the heavenly agencies. {Ms45-1904.17} The three great and glorious heavenly characters are present on the occasion of baptism. All the human capabilities are to be henceforth consecrated powers to do service for God in representing the Father, the Son, and the Holy Ghost upon whom they depend. All heaven is represented by these three in covenant relation with the new life. “If ye then be risen with Christ, seek those things that are above, where Christ sitteth at the right hand of God.” {Ms45-1904.18}
"As the saints in the kingdom of God are accepted in the beloved, they hear: “Come, ye blessed of My Father, inherit the kingdom prepared for you from the foundation of the world.” [Matthew 25:34.] And then the golden harps are touched, and the music flows all through the heavenly host, and they fall down and worship the Father and the Son and the Holy Spirit." Ms139-1906.32
"The Godhead was stirred with pity for the race, and the Father, the Son, and the Holy Spirit gave themselves to the working out of the plan of redemption. In order to fully carry out this plan, it was decided that Christ, the only begotten Son of God, should give Himself an offering for sin. What line can measure the depth of this love?" {Lt12-1901.10}
The three representative powers of the Godhead, the Father, the Son, and the Holy Spirit, were pledged to carry out God’s plan for the salvation of the lost race. Thus fully did the Lord engage the heavenly universe in the work of redemption. How few understand and appreciate this infinite sacrifice!" {Ms139-1907.10}
The pages on the Father, Christ and the Holy Spirit have pages connected to them that are exceedingly valuable to explore.
