Its amazing the false things you can read on the internet. SDA;s do not believe in 3 gods.
2. The 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.)
People have gotten to a point that whatever they believe in their head, somehow makes it true. A false witness is something we should take seriously.
