This is one of the first articles that I read about SK from a former Lutheran who died a Catholic priest. Anyway, here is a quote:

There are Christians who call themselves Kierkegaardians, much as others call themselves Augustinians or Thomists or Barthians. But Kierkegaard provides no school of thought, and most emphatically no “system,” that can be a secure resting place for one’s Christian identity. Kierkegaard offers only a mode of being, of thinking, of living that has no end other than the end of being “contemporaneous” with Jesus Christ, true man and true God, who has no end. The certifying mark that one has accepted what he offers—or, more precisely, what Christ offers—is martyrdom, and Kierkegaard yearned to be a martyr. The word martyr, one recalls, means witness. If Kierkegaard was not to be given the privilege of literally shedding his blood, he would bear witness in other ways. He welcomed the derision of those surrounding him, recognizing in them the same crowd that surrounded the cross of his contemporary, Jesus Christ.
