The choice of issues and the definition of research objective results from the author’s many years of academic and professional work. The author specializes, among others, in guiding and representing spouses in the divorce process. Years of observation led to the idea to study whether there is a correlation between the trend of secularization, lack of prayer and the increasing number of divorces. In addition to using a method appropriate for a lawyer, i.e. the legal-dogmatic method, surveys were conducted in the planned area on 206 respondents. The research problems were aimed at answering the questions: Does progressive atheization have an impact and correspond with the practice of prayer? Does prayer have an impact on the human condition? If so, what areas of human life benefit from prayer? A key problem was to investigate whether prayer can affect the durability of marriages? It is erroneously assumed that Christian prayer occurs and concerns the inner sphere of man. John Cassian, who lived at the turn of the 4th/Vth century between Egypt and southern Gaul, described the phenomenon of constant prayer. While the spiritual benefits of fasting and prayer may be difficult to measure scientifically, there is evidence to support the view that fasting and prayer can have a positive impact on our mental and emotional well-being. The subject has been researched and presented in relation to the trend of increasing number of divorces in Poland.
