Here is a starting point. It is a YouTube clip that I have adapted to suit our needs. The statements made are relevant to a Catholic understanding of salvation history, that is, they are to be viewed from within the knowledge community we call the Catholic Church. Outside that community, the statements are debated.
As you watch the video, make notes to help you remember what the term "salvation history" means.
Look at the graphic below. I found it by googling "salvation history". What can you learn from the image? Which words are meaningless?
When we focused on the video clip above, we started with the notion that salvation history can be represented by a straight line starting with the Fall and ending with the end of time. The Jesus event would be in the middle of the line, much like the graphic above.
I then introduced the idea that Jesus is "the still point of the turning world." So now we have history as a cyclical thing, that is, as Tarley stated, history can (and does) repeat itself. In fact, that is how the Jews view life. Each person experiences Exodus in their lives. The Catholic Church has its liturgical calendar, with its cycle of "seasons".
For the time being, let us consider it as a straight line. What events, people, words and actions do we place along the line? And what is the motive for putting them there?
The answer lies in the word "covenant". God made covenants with people over a long period of time. Covenants are characterised by divine promises. The readings we looked at early in the week identified some of the promises.
