Understanding the Trinity: A Doctrine I Used to Doubt
That our early Adventist pioneers generally opposed the classical doctrine of the Trinity is a well-documented fact. History shows that Adventists continued to study their Bibles, and gradually adopted a belief in the full divinity of Christ, the personality of the Holy Spirit, and the oneness of three divine Persons. By the 1940s the church had become predominantly Trinitarian.
