Nontrinitarianism
Seventh-day Adventists did not believe in the Catholic doctrine of the trinity for the first 50 years of their existence either. The founders of the world wide Seventh Day Adventist Church believed that: "There is one supreme God of the universe and Jesus Christ: The only begotten Son of God!", Statement of Believes, 1873. The change came many years latter, when the founders of the Seventh Day Adventist Church had already 'slept in the Lord"(died).
