This thesis is devoted to the topic catechetical work with children in the Czechoslovak Hussite Church. After presenting into context depicts the subject from two point sof wiew. The first part is devoted to theoretical catechetics, which describes how the catechesis of children theoretically takes place. The sekond part shows you how it really takes place in Hradec Kralove diocese of the Czechoslovak Hussite Church. These two parts are equally divided into three sections. By comparing these sections it is concluded that in practice the fundamental katechetice coincides with the theory. In a formal katechetics, basic points also coincide, but practice may inspire theory rather than vice verse. The material part is of the biggest contradictions, especially in materials that Czechoslovak Hussite Church does (not) offer. Mismatch in this material part of catechetics is essential, and unless a consensus is reached again, the problems that the practice faces, cannot be solved.
