In the Franciscan view, God did not need to be paid in order to love and forgive God’s own creation. Love cannot be bought by some “necessary sacrifice”; if it could, it would not and could not work its transformative effects. Duns Scotus and his followers were committed to protecting the absolute freedom to love in God. If forgiveness needs to be bought or paid for, then it is not authentic forgiveness at all. Love and forgiveness must be freely given or they do not accomplish their deeply transformative healing. Self-serving love does not change the heart. It must be free and undeserved love or transformation does not happen. (Think about that and you will know it is true!)
I’m not sure many Christians recognize the dangers of penal substitutionary atonement theory. Perhaps the underlying assumptions were never made clear, even though thinking people throughout the ages were often repelled by such a crass notion of God. This theory has become a nail in the coffin of belief for many sincere, thoughtful individuals today. Some Christians just repress their misgiving because they think it implies a complete loss of faith. But I would wager that for every person who voices doubt, many more quietly walk away from a religion that has come to seem irrational, mythological, and deeply unsatisfying to the heart and soul. And these are usually not “bad” people!
Christianity can do so much better, and doing so will not diminish Jesus in the least. In fact, it will allow Jesus to take on a universal and humanly appealing dimension. The cross cannot be an arbitrary and bloody sacrifice triggered by a sin that was once committed by one man and one woman under a tree between the Tigris and Euphrates rivers. Frankly, that idea reduces any notion of a universal or truly “catholic” revelation to one planet, at the edge of one solar system, in a universe comprised of billions of galaxies with trillions of solar systems. A religion based on required sacrifices is just not glorious or hopeful enough or even befitting the marvelous creation. To those who cling to Anselm’s understanding, I would say, as J. B. Phillips wrote many years ago, “Your God is too small.” 
World War I and the adversarial mentality.
It’s the eternal argument. When you are fighting a repulsive foe, the ends justify any means and serve as rationale for any selfishness.
Dax’s struggle is not to change the war or to save lives. That’s impossible. The war has won. The struggle is simply to remain a human being, to maintain some contact with goodness in circumstances that are inhumane.
Disillusionment was the classic challenge for the generation that fought and watched that war. Before 1914, there was an assumed faith in progress, a general trust in the institutions and certainties of Western civilization. People, especially in the educated classes, approached life with a gentlemanly, sporting spirit.
As Paul Fussell pointed out in “The Great War and Modern Memory,” the upper classes used genteel words in place of plain ones: slumber for sleep, the heavens for the sky, conquer for win, legion for army.
The war blew away that gentility, those ideals and that faith in progress. Ernest Hemingway captured the rising irony and cynicism in “A Farewell to Arms.” His hero is embarrassed “by the words sacred, glorious and sacrifice and the expression, in vain.” He had seen nothing sacred in the war, nothing glorious, just meaningless slaughter.
.. European culture suffered a massive disillusion during the conflict — no God, no beauty, no coherence, no meaning, just the cruel ironic joke of life. Cynicism breeds a kind of nihilism, a disbelief in all values, an assumption that others’ motives are bad.
Fussell wrote that the war spread an adversarial mentality. The men in the trenches were obsessed with the enemy — those anonymous creatures across no man’s land who rained down death. “Prolonged trench warfare, whether enacted or remembered, fosters paranoid melodrama,” he wrote.
The “versus habit” construes reality as us versus them — a mentality that spread through British society. It was the officers versus the men, and, when they got home, the students at university versus the dons.
George Orwell wrote that he recognized the Great War mentality lingering even in the 1930s in his own left-wing circles — the same desire to sniff out those who departed from party orthodoxy, the same retelling of mostly false atrocity stories, the same war hysteria. As Christopher Isherwood put it, all the young people who were ashamed of never having fought in the war brought warlike simplicities to political life.
.. Some of the disillusioned drop out of public life, since it’s all meaningless. But others want to burn it all down because it’s all rotten. Moderation is taken for cowardice. Aggression is regarded as courage. No conciliatory word is permitted when a fighting word will do.
Today we face no horrors equal to the Great War, but there is the same loss of faith in progress, the reality of endless political trench warfare, the paranoid melodrama, the specter that we are all being dehumanized amid the fight.
