U članku se promišlja o vrlo važnoj, ali i zapostavljenoj temi kršćanstva i katoličke teologije, o temi bratstva. Ako neke teološke teme i mogu ostati samo u području spekulativnoga, misaonoga, tema bratstva u svojoj biti traži konkretna ostvarenja i pokazatelje. U članku se, stoga, najprije predstavlja ponovno otkrivanje aktualnosti teme i pojma bratstva u Crkvi i teologiji. Navodi se nekoliko misli općenito o pojmu „brat” i „bratstvo” i predstavlja kršćansko poimanje bratstva. Pokazat će se kako ono, makar u nekim vidovima, može biti i model življenja i razumijevanja bratstva uopće. Potom se, na tragu tih promišljanja, tumači poslanje vjeroučitelja unutar i polazeći od kategorije bratstva. Pokazuje se kako školski vjeronauk može poučavati o bratstvu, kao i stvarati bratstvo. Na kraju se sasvim konkretno navode neka ostvarenja i inicijative po kojima se ostvaruje bratstvo vjeroučitelja u Splitsko-makarskoj nadbiskupiji. The article reflects on a very important but also neglected theme of Christianity and Catholic theology, the theme of brotherhood. If some theological themes can remain only in the realm of speculation, thought, the theme of brotherhood in its essence seeks concrete realizations and indicators. Therefore, the article first presents a rediscovery of the relevance of the theme and concept of brotherhood in the Church and theology. A few general thoughts on the term ‘brother’ and ‘brotherhood’ are given and present the Christian understanding of brotherhood. It will be shown how, at least in some ways, it can be a model for living and understanding brotherhood in general. Then, following these reflections, the mission of religious education teachers is interpreted within and starting from the category of brotherhood. It shows how school religious education can teach about brotherhood, as well as create brotherhood. At the end, someaccomplishments and initiatives are mentioned quite concretelyby which the fraternity of religious teachers in the Split-MakarskaArchdiocese is realized.
