This study seeks to explore the origin and formation of the so called “Hungarian traditional” theology within the Reformed Church of Hungary from the 1840s till the 1860s. The research paper also throws light on how the new orthodoxy movement of Debrecen grew out of this trend from the 1870s which had an enormous impact on the Protestant theological landscape of Hungary, the largest Protestant community in Central Europe. Hungarian new orthodoxy precedes both the orthodoxy developed by Kuyper and the Barthian neoortodoxy which is a much later theological trend. It also points out that Western European Protestant theological trends did have a great impact on the Hungarian theological context. This work aims to demonstrate how the doctrinal views of Hungarian traditional theology were developed through the works and life of selected influential leaders like Imre Révész senior, Lajos Filó, József Heiszler while debating with liberal theology. Reference will be made to the foreign impact of conservative theologies represented by evangelical, Pietist and mediating theologies of Germany, the Netherlands, Switzerland and Britain. The doctrinal debates appeared in contemporary journals. Analysing the texts, it is possible to delineate what the stance of traditional theology was about: inspiration of the Scripture, the uniqueness of Revelation, the doctrine of original sin, the necessity of atonement, deity of Jesus Christ, the confession of Trinity, faith in the last judgement and Christ’s second return and the reality of miracles.
