In Bosnia-Herzegovina, the 51^st World Communications Day is celebrated on 24 September, the last Sunday of September, as decided by the Bishops’ Conference in 2003. The Communications Commission of Bosnia-Herzegovina bishops prepared a subsidy for all pastoral operators, and for media workers. The small report includes an introduction signed by President of the Commission Msgr. Tome Vukši, the message of the Pope on the 2017 World Day, a prayer proposal for believers, and an article by Director of the Catholic Weekly Josip Vajdner in “Miranda Prorsus”, the encyclical of Pope Pius XII on cinema, radio and TV, 60 years after its publication. At the same time with the words of Pope Francis, Msgr. Vukšić asked “all media operators” to collaborate with the ones “already spreading hope and trust, without which it is impossible to produce a happy human society”. That is even truer in “complex societies, such as Bosnia-Herzegovina”, where everyone is asked “to build up trust between persons and peoples, to strengthen hope for a better future, fist of all, through mutual respect”, for “identities as well as ethnic, linguistic, cultural and religious diversities,” so as “to promote social integration, cooperation and economic development”.
