Can you provide a link to the article written by MLK that supports this?
Yes. These were not articles but the writings of Martin Luther King Jr. while at Crozer seminary. There are several where MLK states that Jesus was not born of a virgin, was not God, did not physically rise from the dead, is not coming again bodily and there is no bodily resurrection. His reasoning is akin to that of liberal theologians (that his disciples could not articulate Christ in any other way, but the expression is not literal to the events). MLK stated that the disciples recognized Christ as "divine" or the "son of God" because he had opened himself up to the "spirit of God" and was Jewish, but did not hold a Jewish mentality about humanity. They, according to MLK, reconciled this biologically because they had no concept of science as we know it.

Here is one example from his writings at Crozer:
"The orthodox attempt to explain the divinity of Jesus in terms of an inherent metaphysical substance within him seems to me quite inadaquate. To say that the Christ, whose example of living we are bid to follow, is divine in an ontological sense is actually harmful and detrimental. To invest this Christ with such supernatural qualities makes the rejoinder: “Oh, well, he had a better chance for that kind of life than we can possible have.” In other words, one could easily use this as a means to hide behind behind his failures. So that the orthodox view of the divinity of Christ is in my mind quite readily denied. The true significance of the divinity of Christ lies in the fact that his achievement is prophetic and promissory for every other true son of man who is willing to submit his will to the will and spirit og God. Christ was to be only the prototype of one among many brothers."
"The Humanity and Divinity of Jesus"
He also preached an Easter sermon at his church (Dexter Avenue in Montgomery AL) where he describes how orthodox Christianity came to hold the myth of a bodily resurrection and eternal life (he attributed bodily resurrection to Hebrew philosophy and an eternal spirit to Greek philosophy brought into the faith by Paul). So MLK could speak of the Resurrection and the Empty Tomb, but his meaning was very different from a Christian meaning. He understood the expression of a bodily resurrection to be a mythological representation of the truths (the "spirit of God") living on after Christ's death. The "second coming" therefore occurs when a man is opened to those truths.
"Whatever you believe about the Resurrection this morning isn’t important. The form that you believe in, that isn’t the important thing. The fact that the revelation, Resurrection is something that nobody can refute, that is the important thing. Some people felt, the disciples felt, that it was a physical resurrection, that the physical body got up. Then Paul came on the scene, who had been trained in Greek philosophy, who knew a little about Greek philosophy and had read a little, probably, of Plato and others who believed in the immortality of the soul, and he tried to synthesize the Greek doctrine of the immortality of the soul with the Jewish-Hebrew doctrine of resurrection. And he talked, as you remember and you read it, about a spiritual body. A spiritual body. Whatever form, that isn’t important right now. The important thing is that that Resurrection did occur. Important thing is that that grave was empty. Important thing is the fact that Jesus had given himself to certain eternal truths and eternal principles that nobody could crucify and escape. So all of the nails in the world could never pierce this truth. All of the crosses of the world could never block this love. All of the graves in the world could never bury this goodness. Jesus had given himself to certain universal principles. And so today the Jesus and the God that we worship are inescapable."
