Markham tells us that the notion of "Christ the Victor" over evil used to be a very popular Christian conception of how Jesus brings salvation to humankind. Reread Markham's account if you don't remember it in detail. It's all very mythological in character. Cosmic battles between good and evil, tricky ransoms being paid to the Devil, and so on. Perhaps that talk once made sense to people who were deeply rooted in mythological thinking, but I don't see how it is likely to move anyone today.
Yet, as Markham suggests, people today can relate to the notion that there are forces of evil loose in the world. Different people may identify those forces in various ways. Our President some years ago famously identified three nations (Iraq, Iran, and North Korea) as an "axis of evil". That is one example of a contemporary use of the idea of forces of evil. Others would point to the power of greed and selfishness, or to sexism and racism. These are just some examples of how this idea is used.
If the notion of forces of evil does indeed make sense in today's world, then perhaps the notion of Christ the Victor over evil can also make sense somehow. The question will be how such an account might be put together.
Look at it this way: what about the Jesus story might a Christian theology point to as showing
a) how he was confronted by some sort of universal force of evil that afflicts all of humankind, and
b) how features of his life story constitute victory over those forces.
That is where the Borg reading comes into play. Perhaps Borg's understanding of the Jesus story can be the basis of a contemporary understanding of Christ the Victor. So, look for things that Borg says that might help answer (a) and (b) above. Write a paragraph about a possible Borg answer to (a) and another paragraph about an answer to (b).
(Note that you are here being asked to do an exercise in conceptual connecting. You can do this exercise without actually believing that the Jesus story is historically or metaphorically true, and without agreeing with the theological construct you are creating. That is, this is about trying to understand the Christ the Victor approach to Christian soteriology.)
In class we will see what you have come up with. And then we'll try to fill in some of the answers to the questions on the Christian soteriology study guide as they pertain to the Christ the Victor conception.
