The subject of the analysis is the spirituality of hidden religious life and its conditions. The truth about hidden God fascinated Honorat Koźmiński, a Capuchin who lived at the turn of the 19th and 20th centuries. He initiated more than 20 male and female religious congregations whose members did not wear uniform clothing and experienced their consecration in hiding from the world. Not wearing the habit, according to the plan of the Founder, was not determined solely by the socio-political situation. The article shows hiding as a special lifestyle characterized by humility, quietness, diligence and Franciscan minoritas. The article reflects on the commitment of the Capuchins and their formation work among men and women in socio-political and ecclesial conditions of the second half of the 19th century.
