Through an exploration of the editions of the hymnal published in 1924 by Márton Pálffi, this study provides insight into the reverence for tradition surrounding the hymnal, as well as the arduous but unsuccessful efforts made by those aiming to rejuvenate it. Politics often encroached upon the life of the Church, evident in the evolution of the hymnal. The changes of political power and country borders, as well as the imposition of communist censorship, have also significantly influenced the Unitarian hymnal. Despite all efforts, errors persisted in editions published post-1989. This research endeavours to trace these changes across a century of history.
