Was Martin Luther King Jr. An Atheist?

Today we celebrate Reverend Dr. Martin Luther King Junior’s birthday. In the spirit of the celebration, the Atheologist performed an online search with these four words: Martin, Luther, King, and hero. One of the websites that came up in the search was, greaterthings.com, in which the supposed owner of the site, Chuck Baldwin states that the good doctor King was:

"a philanderer, a violent person, a plagiarizer, that he was cozy with Communists and worst of all he came to renounce the fundamental tenets of the Christian faith. He rejected Christ's deity, His virgin birth, and His physical resurrection. He also rejected the authority and inspiration of the Holy Bible."

The Atheologist was taken by surprise to say the least, why would Doctor King have rejected the authority of the Holy Bible? Was he an Atheist?
To get some insight into this question the Atheologist turned to Mark Knoll, the well known Bible expert, Mark says:

"Martin Luther King Jr. was not an Atheist; he was an Apostate Minister and the reason that he rejected the authority of the Holy Bible, was mostly due to his incorrect interpretation of it. While it is true that the Bible is full of stories containing cannibalism, child killing, rape…etc, and has rules for keeping and treating slaves, and for a black man in this country, which I believe he was, slavery, was a no-no. There are some parts of the Bible that actually teach us to be nice to one another. Martin Luther King Jr. did not read the bible properly. The proper way to read the Bible and get the most out of it is to skim over and ignore the parts that may cause you to distress or may confuse you and just read the ones you like, or better yet just have your minister, pastor or parish priest read them to you."
