ABSTRACT
Nikolaos Nissiotis' important work on the relationship of existential thought and Christian faith first appeared in 1956 in the form of a doctoral thesis submitted at the Theological School of the University of Athens; a second edition appeared in 1969. Nissiotis was a quite well-known Greek theologian and philosopher who also studied psychology and taught not only in Greece but also in Geneva. His work is a fascinating example of interdisciplinary research, where philosophical and theological issues are interwoven and posited in an interesting way. Nissiotis enjoins the orthodox researcher of Søren Kierkegaard's work always to bear in mind that Kierkegaard's stance towards institutionalized Christianity springs from the excesses of his Protestant environment. He acknowledges that Kierkegaard's thought could serve the Christian as an initiative to become more authentic, more active in his or her faith.
