Dave Pack promotes himself as the worlds greatest theologian, writer and TV preacher. Pack claims to have written all of the booklets that RCG puts out. When he got humiliated a few years ago for accusations of plagiarism in his blatant copying of HWAs booklets, he set about reediting everything.
One of the booklets he claims to have written was one on the trinity. It is a typical COG mishmash of anti-trinitarian mumbo-jumbo that need serious scholarship updates.
However, Did Dave actually write it? Sources says he did not and has lied about it. The person who rote it has commented on the Rightly Divining The Word of Truth blog. The owner of the blog read Dave's book on the Trinity and wrote a small entry about it. In the comments that followed a person admitted that he wrote it and not Dave.
The person also admits that the research was poor.
