Whoaaaaa... nearly burnt my retinas out reading the replys to this question, well I will try to keep 'on topic'
I first came across Doc. Ruckman 15 years ago, I read an article well two actually about him in the 'Sword Of the Lord'. His name had come up a few times, I am a 101% KJV Only-er and I wrote him asking for his side of the criticism made against him. Well his reply sent me on a quest to either prove or disprove his arguments.
That is my point, he is not the fourth member of the Godhead, but he sure makes you work!
Even in the controversial areas and we all know what they are, he at least gives Chapter and Verse for his beliefs therefore we can either take them or seek to answer them ourselves by going to the Scriptures. Thats the rub... he is getting your nose into the Book and not relying on another's interpretation but dig out your own answers....
I hold unashamedly Dr.Ruckman in high regard, he has personally blessed me in many ways, in fact he saved my sanity (but thats a different story

)
Do I think he is infallible?? Nooooooo! he is a man as we are and subject to the same pitfalls as we. I find it interesting that his detractors attack his personal life rather than the issues at hand, perhaps we should poke around in their lives and see what's lurking???
As many have said here 'spit the bones and eat the meat' is sound advice if you cannot agree with him.
