Because The Spirit of Prophecy, volume 4, was called for in the European languages, Ellen White felt she must write out more fully the controversy scenes involving places in Europe. The result was the book known today as The Great Controversy, first published in 1888. EGWBB 7.3
Back again in the United States, Ellen White made her home at Healdsburg, California, but attended the General Conference session of 1888 in Minneapolis, Minnesota. In the following months she traveled and preached, seeking to unify the church on the doctrine of righteousness by faith. During this same period she worked on Patriarchs and Prophets, which appeared in the year 1890. EGWBB 7.4
