The General Synod of 1820 is the subject of my Master's thesis. I believe that the topic and the sources it reveals are indispensable for the research of the Transylvanian Reformed Church history. I will start from the life of the church in the 19th century and move towards the source that I have uncovered. In the excavated source, points appear which are connected with the liturgical history, the history of the order, and the rules and customs of burial. A slice of this will be presented and unpacked in this essay. The information and the improved readability of the record will be useful for all those who wish to enrich their knowledge of church history.
