La disputa al concilio di Basilea tra Giovanni da Ragusa e Giovanni da Rokycana

The study is aimed to sketch the dispute which took place on the Council of Basle between the representatives of Czech Church and Roman Catholic Church, namely between John of Rokycany and Ivan of Dubrovnik. The theme of the discussion was mainly the question of communion under both kinds for the laity, which could be regarded just as a disciplinary matter. In: reality, both disputers show that there are ecclesiological consequences: How should the Church be understood? What is Jesus’s relation to this church? The dispute thus reflected the Church reform initiated by John Wycliffe and advanced by John Hus. The question of communion under both kinds for laity provided an opportunity to rethink the nature of the Church, the role of authority in it and the relation between the Church and Eucharist. This would, however, presuppose a certain way of perceiving the Eucharist (a sacrament or a sacrifice?), which both theologians present to justify their notion of the Church. In: order to resolve these questions, it was necessary to face a methodological problem: How to interpret the Bible and who is the supreme authority to offer an authentic interpretation? According to John of Rokycany, it is the Church while Ivan of Dubrovnik claims that it is the authority of the Church. The dispute is thus an example of the relation between the mysteries which theology should pursue.
