This Reprint provides an interdisciplinary platform showcasing the latest research related to the social dimensions of prayer. The collected chapters examine the impacts of prayer on quality of life and its role within public, cultural, and economic contexts, highlighting how religious practices evolve in response to technological and cultural challenges. The Reprint comprises 13 chapters. It begins with a theoretical article reviewing religiosity and prayer through the framework of actions and products developed by Kazimierz Twardowski. The subsequent section shifts the focus towards empirical analyses, including studies on the use of Artificial Intelligence (AI) in prayer practices, the validation of the Prayer Importance Scale, the impact of prayer on human development through choral singing, and the role of prayer in consumption. Further chapters explore African religiosity through the lens of "violent prayer" in Nigeria and highlight the importance of prayer in literary studies through the works of Felix Timmermans and 20th-century Russian Orthodox culture. The Reprint also investigates interactions between prayer and the socio-economic sphere, addressing the management, financing, and multifunctional use of sacred sites, as well as the institutional-economic framework of the Church in Germany. The concluding reflections explore the existential and systemic significance of prayer, demonstrating how spiritual values translate into the theoretical and practical foundations of economics, from the scholastic inspirations of free-market economics to the concept of the common good in Catholic social teaching.
