The text describes the ecumenical atmosphere at the Jircháře seminary building in Prague during the 1960s. Following World War II, the building was owned by the Evangelical Church of Czech Brethren but hosted students from various Protestant denominations, reflecting the ecumenical spirit of the Comenius Faculty. A significant development was the establishment of the "Jircháře Thursdays," seminars that initially fostered cooperation between the Comenius and Hus Faculties. Under the leadership of figures like Jiří Němec, this platform eventually expanded to include Catholic intellectuals such as Jan Sokol and Karel Floss. Despite opposition from conservative Catholic circles who reported these activities to Archbishop Tomášek, a breakthrough occurred when J. L. Hromádka and other key initiators were invited to the Archbishop's palace. This meeting resulted in a "nihil obstat," effectively legitimizing inter-confessional dialogue. This period represents a crucial chapter in Czech ecumenical history, characterized by the breaking down of historical barriers and profound intellectual exchange between Protestant and Catholic thinkers in Czechoslovakia.
