This sermon of the famous professor, based on the text of John 14:1, is hardly familiar for readers of Hungarian theological literature. However, it is known that a Hungarian summary was made at the time the sermon was held, and once published, an exact translation of the German text was made. Our aim is to review Barth’s visit to Oradea (Nagyvárad) on 7–8 October 1936, to revisit the above mentioned sermon, as well as the short interview with Barth that was published in one of the local newspapers at that time. This interview reflects Barth’s prophetic vision: Bolshevism and fascism must retreat at the sight of Christian faith. There is no trace of this conversation in the Barth-bibliographies, although this interview is still crucial,even after 78 years.
