SDA Belief No.2 - The Trinity:
There is one God: Father, Son, and Holy Spirit, a unity of three co-eternal 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. He is forever worthy of worship, adoration, and service by the whole creation.

(Deut. 6:4; Matt. 28:19; 2 Cor. 13:14; Eph. 4:4-6; 1 Peter 1:2; 1 Tim. 1:17; Rev. 14:7.)
