Aim. The aim of the article is to identify opportunities for religious education in the field of promoting the values of sustainable development. By identifying key concepts, define options for future strategies in the implementation of sustainable development values in school teaching of religious education. Methods. The starting point is the analysis of the current religious education curriculum, which governs the teaching of religious education and is approved by both state and church authority. Based on the analysis, identify strengths and weaknesses and define potential areas within the curriculum where sustainability values can be applied. Results. The values of sustainable development and Christian values are based on a common anthropological platform, which is based on the dignity of the human person. Religious education should also be based on this platform. Conclusion. In order to apply the values of sustainable development, it is necessary to adjust the current curriculum in terms of content and scope of topics. At the same time, it is necessary to innovate in the way of training future teachers. The goal of innovations is the internalization of sustainability values within the value orientation of both teachers and students. Cognitive value. Christian values and the values of sustainable development are not in conflict. The content of the religious education curriculum has the potential to innovate its content to meet the current requirements of the United Nations (UN) agenda as well as the teachings of the Magisterium.

In the recent past, the question of determining the optimal city size in relation to the quality of urban life (QoUL) was raised of city inhabitants. This article has evaluated the correlation of the QoUL index in cities in relation to the number of inhabitants. We also deal with selected variables for which we assume a relationship with QoUL. The authors who calculated the indices of the quality of urban life equated the quality of life with its objective dimension considered as the quality of the place. It turned out that growth in the number of inhabitants of Slovak cities did not correlate with improving quality of life. Our article examined QoUL in two different countries on a scale of 0–10 through questionnaires. The obtained values are a subjective assessment. From a global point of view, one city is small and the other is big. The small city achieved better results in international rankings of quality of life, and it was assumed that this fact would also be reflected in the quantification of the quality of urban life. One hypothesis was that a small city will achieve better urban life quality values than a large city. The paper presents the results of measurement and correlation.

Aim. The article describes the philosophical background of competency education and analyses the weaknesses that are present in curriculum changes, focusing on the absence of dynamic acceptance of otherness. Concept. The starting point is a reflection on the philosophical background of education as a repetition and production of the same. The basic principles of the post-metaphysical approach of education to otherness and the interpretation of the innovation curriculum in relation to these principles are presented. Results. Curricular changes and innovations appear to be cosmetic adjustments in which the traditional philosophical and pedagogical principles of passive reception of knowledge and acquisition of large amounts of knowledge are preserved. Conclusion. Changing the curriculum requires a change in teachers' attitudes as well as a change in the school education system. It is necessary to define who the teacher is, who the pupil is. Parents must identify with curricular reform and see it as a positive change for their children. Cognitive value. Curricular reform cannot be done without systemic changes in education. All participants in the change must be familiar with and identify with the new paradigm and its philosophical background, otherwise it will not be possible to realise the transition to competency pedagogy.

Konštantínove listy/Constantine’s Letters is an international scientific journal which has been published in Constantine the Philosopher University in Nitra since 2008. The main goal of the journal is to present problems and themes intertwined with the cultural and political history of Great Moravia during the 9th century as well as continuity of Cyrillo-Methodian tradition in later times. Next, there is also space for other adjacent topics connected with Slavonic and Byzantine history, philology, philosophy, literature, cultural relations as well as medieval and early modern age ecclesiastical history and iconography.

The study presents the results of research into the current state of selected religiosity phenomena in the Slovak Republic and models possible pathways for the future development of the selected phenomena. The starting point is an analysis of three decades of development of religiosity in the region from 1989 to the present day. The input data were obtained as part of a research project focused on development prospects. The data refer to the second and third decades of the reporting period. The data are subjected to statistical and correlation analyses. Analyses deal with the phenomenon of faith and its content, rational and liturgical interpretations of religiosity, and questions of the meaning of existence and the moral dimension of faith. Thanks to the application of selected religionist theories, this formulates possible paths which the religiosity of the selected region will take, describing the potential as well as the risks of development for individual directions of development.
