When it comes to VPW and plagiarism, it is easier to list what VP did not steal than what he did. The monograph by Juedes and Valusek "Will the Real Author Please Stand Up?" quotes several examples of plagiarim, with the original author in 1 column and VP in the column next to it. Here are examples in addition to Stiles and RTHST:
+ EW Kenyon, the Father and His Family --- VP How to Be a Christian (New Dynamic Church)
+ EW Bullinger, Selected Writings , How to Enjoy the Buble --- VP, Are the Dead Alive Now
+ Bullinger, The Knowledge of God --- VP, The Counsel of the Lord (The Bible Tells Me So)
+ Bullinger, Figures of Speech Used in the Bible --- VP, Rediscovering Figures of Speech (The Way Mag 1984)
+ Bullinger, How to Enjoy the Bible --- VP, Search the Scriptures (TWM 1984)
+ Bullinger, The Church Epistles --- VP, God's Magnified Word
+ Bullinger, The Giver and His Gifts --- VP, Receiving the Holy Spirit Today
In the case of RTHST, almost the whole book was stolen from Stiles and Bullinger. Juedes also wrote a parallel column comparison showing which chapters were stolen from which authors. RTHST "grew" as he found more authors to steal from, which is obvious if you compare early editions of RTSHT.
It's also clear VP plagiarized from the very beginning (1953 at least) to the very end of his life (1984), a life long lie.
Plagiarism isn't just "learning" from people. It's quoting or paraphrasing them in a book or article without citing the source. The lie is that people think you're an originator instead of a copier. He would have been fired from an faculty; instead he's admired and nearly worshiped by many.
