This paper deals with the problem of secret non-catholicism in the northeast Bohemia at the end of the first third of the 18th century and its connection with the religions movement of local serfs. It points out the role of reading religious literature like the Bible, prager-books and hymn-books on secret non-catholics meetings. That was an irreplaceable part of their speeches as was the role of religious legates from the milieu of Sorbian pietistical communities. A sudden abnormal concentration of religious emissaries in a small part of Opočno's manor, the spectre of newle smuggled books sold by emigrants even their apparent help with the formulation of requests of serfs to autorities and maybe the autorships of the creed of the religion gives evidence of a strong influence of emigration. In the Memorial's formal dogmatics we can find clear symptoms of the pietistical influence on the formulation of official request. We can assume that the text of the creed of the religion is not a local non-catholics production. It evidently grew out of a remarkably vague awareness of former faith of ancestors influenced by Lutheran pietism in the 18th century. The fading influence of the ideas of Czech reformations of 16th century can be seen even in the structure of non/catholic books. Contraband books prevails at the end of the first third of the 18* century. These books had a great influence on formalization of dogmatic that necessary to refer to the leading local figures of Opočno events that happened in the September of 1732. A use of catholics production was not an Exception. The reading of secret non/catholics in privat and meetings and its structure deals ill-definated dogmatics positions of this rural community.
