Kalniuk, Jan2023-01-162023-01-162008Polonia Sacra, 2008, R. 12 (30), Nr 23 (67), s. 43-60.1428-5673http://theo-logos.pl/xmlui/handle/123456789/3123The Eucharist on Sunday and on other festive days, which has been passed on to us by tradition, holds an enormously rich content of both spiritual and pastoral nature. For the first Christians it was unthinkable not to participate in a Holy Mass on Sunday and not to commune, and not because it was a duty, but out of one's own will. For centuries the Church has attached a great importance to keep Sunday as the Lord's Day and the Church discipline treats it as a sacred duty. However, participation in the Holy Mass on Sunday and on other festive days should not be treated as an order, but first of all as a need inscribed in the very essence of Christian existence. Each Christian should realize that he or she cannot live the faith and fully participate in the life of the Christian community if they do not participate in the Eucharist gathering on regular basis.plAttribution-NonCommercial-NoDerivs 3.0 Polandhttp://creativecommons.org/licenses/by-nc-nd/3.0/pl/wychowaniewychowanie religijnemoralnośćEucharystiaMsza świętaniedzielaświętanabożeństwaświętowaniechrześcijaństwowspólnotapobożnośćwiaraupbringingreligious upbringingmoralityEucharistMassSundayholidaysreligious servicescelebratingChristianitycommunitypietyfaithetykaethicssacramentssakramentyArticle
