A famous megachurch pastor said Rev. Dr. Martin Luther King Jr. was “not a Christian at all.”
LGBTQ Nation reported that 85-year-old white man Grace Community Church pastor John MacArthur made the assertion last month in a sermon. 
Right Wing Watch noted that he chastised Together for the Gospel [T4G] evangelical pastors for commemorating King some years ago.
“[T4G] bought into the deceptiveness of the woke movement and the racial baiting that was going on a couple of years ago, and it literally put them out of existence,” MacArthur added. “The strange irony was a year later, they did the same thing for Martin Luther King, who was not a Christian and lived immorally.”
MacArthur said, “I'm not saying [King] didn't do some social good, and I've always been glad he was a pacifist or he could have started a real revolution. You don't honor a non-believer who slandered Christ and the gospel."
LGBTQ Nation reported that MacArthur stated, “The Bible is abundantly clear — slavery is the heart of what it means to be a true Christian,” adding that Christianity does not release slaves. Christianity does not guarantee equal social rights. Jesus did not advocate equal rights or disrupt the social order. Instead, they all said to submit to your masters with fear of God and respect. You must submit to them, whether they are kind or ridiculous.
MacArthur also denies homosexual people exist.
“Nobody is gay. He told The Friendly Atheist that people commit adultery, homosexuality, lying, stealing, and cheating.
It's like saying, "I keep robbing banks, but I'm a robber." I rob banks. What now? I rob banks. That doesn't excuse your actions, MacArthur said. “Do certain impulses steer people that way? Yes. I think letting individuals describe themselves as gay is deadly.”
