A kairotic moment is a moment that shapes the history of everything that comes after it. In the Old Testament, for example, the exodus was a kairotic moment. In the New Testament, the birth of Jesus, the cross, and the resurrection are all kairotic moments. The closest word we have to this in English is the word historic. Every event that takes place in history is historical, but not every event that takes place in history is deemed historic. To be historic it has to have special significance and special impact on life. So the Bible is the record of God’s historic works of redemption within the context of space and time. 

“Once upon a time . . .” These words signal the beginning of a fairy tale, a story of make believe, not an account of sober history. Unlike beginning with the words “once upon a time,” the Bible begins with the words, “In the beginning God….” This statement, at the front end of the entire Bible, introduces the Pentateuch or the first five books of the Old Testament, and it sets the stage for God’s activity in linear history. From the opening chapters of Genesis to the end of the book of Revelation, the entire dynamic of redemption takes place within the broader setting of real space and time, of concrete history.

The historical character of Judeo-Christianity is what markedly distinguishes it from all forms of mythology. A myth finds its value in its moral or spiritual application, while its historical reality remains insignificant. Fairy tales can help our mood swings, but they do little to give us confidence in ultimate reality. The twentieth century witnessed a crisis in the historical dimension of biblical Christianity. German theologians made a crucial distinction between ordinary history and what they called “salvation history,” or sometimes “redemptive history.” This distinction was based in the first instance on the obvious character of sacred Scripture, namely, that it is not only a record of the ordinary events of men and nations. It is not a mere chronicle of human activity but includes within it the revelation of God’s activity in the midst of history. Because the Bible differs from ordinary history and was called “salvation history,” it was a short step from there to ripping the biblical revelation out of its historical context altogether. No one was more important in the snatching of the Gospels out of history than the German theologian Rudolf Bultmann. Bultmann devised a new theology that he called “a theology of timelessness.” This theology of timelessness is not interested in the past or in the future as categories of reality. What counts according to Bultmann is the hic et nunc, the “here and now,” or the present moment. Salvation doesn’t take place on the horizontal plane of history, but it takes place vertically in the present moment or what others called “the existential moment.”

We might ask the question: How long does a moment last? There is a parallel between Descartes’ concept of the “point” and the existentialist’s concept of the “moment.”
