What are the motifs in A Kierkegaard Anthology by Robert Bretall?

Kierkegaard's favorite writing is the Training in Christianity. He explains this by arguing that his entire life has been about understanding what it means to be a Christian and to be a Christian within a Christian Society. The Training in Christianity directly addresses this question. The core idea of the Training in Christianity is that we only understand Christianity when we are "contemporaneous with Christ." In other words, to be a Christian we must be Christ's contemporary.
