While there is no intention to advocate that what I wrote somehow recommends that non-theists adopt something along the lines of my post, I cannot take credit for the "happy-clappy spin," as you put it.
Having thoroughly imbimbed and promoted the Kool-Aid of the Governing Body of the Jehovah's Witnesses for two decades, from the 1980s onward, I was totally of the opinion that the JWs had the correct and generally accepted view of the Jesus story, that as the JWs served it, this version of the Christian mythology was generally accepted as a ransom story, about providing a dead victim to set the scales of justice aright before the mighty God Jehovah who was doing this becuase someone ruffled his feathers by challenging his sovereignty.
Around ten years after disassociating from the Jehovah's Witnesses, I came across the annual Christmas prayer of the Catholic pope, who at that time was Pope John Paul II. I believe it used to be printed every year in newspapers, if memory serves me right.
Far more poetic than what I described above, the prayer mentioned these points I touched on and more. He said something along the lines of "God became man in order to sacrifice his life so that man can have the eternal life of God," or something along those lines.
I had never been a Trinitarian, not before becoming a Witness or after leaving. So I only knew what the Watchtower had taught us about the subject. But the prayer of the Pope had me curious. What was he talking about? That was nothing like the Incarnation I had learned from the Watchtower (I still held that some of the views of the Witnesses were true, so at that time I had not bothered to revise my education on what Trinitarians believe).
I wrote the above post because it is what the Trinitarian doctrine is about. I learned that the Witnesses were very off base and liars about even that. Catholics, Orthodox, and Protestants don't believe that Jesus gave up his life as a sacrifice to cover Adam's sin, as a sacrifice to appease God, but as an act of redemption, as an offering to humanity.
The theology is very ancient, but it goes like this: Adam's life led to the death of humanity, but Jesus' death led to their life. Adam died by eating fruit from a living tree, humanity lives by "eating the flesh and blood" from the dead tree of the cross. Adam, in an attempt to be like God, gave death to his children, but God, in his attempt to become human, gave life to humanity. The sacrifice of the Jews were animals offered to God, but the sacrifice of God was the life of his Incarnate Son as an offering to humans.
Again, I am sure many of you believe it is nonsense, either way. And I would not argue with you nor claim your view wasn't right, I was merely pointing out that what the Witnesses believe is so backward and empty compared to actual Christianity, that their exegesis is more ignorant than the mythology. They can't even understand what many consider little more than a fairy tale right. They are like poor readers, unable to understand even the most rudimentary of simple children's tales.
Essentially they have turned what others see as a beautiful story into one of a bloodthirsty divinity who, becuase of his pride being hurt, has to have the most perfect of humans suffer and die. I came up with neither "spin" on the tale, but I am rather embarrassed that for almost 20 years I peddled the stupid version.
