In the brotherhood book there are detailed descriptions of ceremony of aggregation's introduction to Basilian chapel in Podwale street, election of the brotherhood authorities, the list of items and funds that the confraternity owned. The book contains the information which let us know the names and the functions of monks who lived in the monastery in Warsaw, and it also gives the knowledge about the relationship between monks and the brotherhood members. St Onufry brotherhood had mainly clerical character but its members paid a lot of attention to furnish and decorate the orthodox church.
