This is the statement on the trinity found in the official website of the Seventh-day Adventist Church website adventist.org/trinity

There is one God: Father, Son, and Holy Spirit, a unity of three coeternal Persons. God is immortal, all-powerful, all-knowing, above all, and ever present. He is infinite and beyond human comprehension, yet known through His self-revelation. God, who is love, is forever worthy of worship, adoration, and service by the whole creation. (Gen. 1:26; Deut. 6:4; Isa. 6:8; Matt. 28:19; John 3:16 2 Cor. 1:21, 22; 13:14; Eph. 4:4-6; 1 Peter 1:2.)
