Douglass was a prominent figure in the 1970s advocating
Last Generation Theology, publishing articles in what is now the
Adventist Review supporting LGT, along with editor
Kenneth H. Wood. He was a leading theologian within the Adventist church. A key contribution to LGT by Douglass was his articulation of what came to be known as "The Harvest Principle". Herbert E. Douglass developed essentially the very same concepts but independently of Andreasen. Douglass was writing his editorials in the Review in favor of the same belief, but he had never read Andreasen. Finally, after these editorials he read Andreasen's views and did find much commonality. But Douglass had developed his concepts, just as Andreasen had, via his careful study of Scripture and reading of Ellen G. White's writings. Douglass taught that Christ's victory over temptation was not on the basis of His divinity but was due to His reliance upon prayer, the study of the Scriptures and reliance upon His Father. This victory was gained in Christ's humanity and His method is available to all men. In this way Christ had no basic advantage over fallen man, according to Douglass, except that man has sinned and Christ has never fallen. This whole emphasis on the humanity of Christ and His identity with the sinner played a vital role in Douglass' theology. Douglass believed that the example of Christ's humanity is vital for the solution to the "great controversy" between Christ and Satan. God is waiting for the possible to happen when a whole generation of fallen men and women will follow the example of Christ, live as He lived in His humanity and finally vindicate the character of God. A key contribution by Douglass was his articulation of what came to be known as The Harvest Principle. Douglass believed that man's performance has not always equaled that of Christ. The time will come at the end when fallen man will reduplicate the life of Jesus. In the 'harvest' principle Douglass had found an answer to the problem of man's apparent inadequacy. Just as the plant grows from the seed to the stalk and then to the full grain, so Douglass saw each generation of believers growing and developing until we come to a generation which has achieved maturity and perfection. Pointing to and , Douglass argued that God is waiting for a ripe harvest, and as soon as that harvest "is fully ripe", He will thrust in His sickle and reap the earth - the
