Among young people, symptoms of social change emerge in a multiple manner. This observation by Karl Mannheim inspired the concept of the survey of social and religious attitudes conducted by the integrated research team of employees of the Department of Sociology of Religion in the Institute of Sociology at Cardinal Stefan Wyszy¿ski University in Warsaw and Institute for Catholic Church Statistics SAC. The title of the book is an intentional reference to the concept of social constructionism. This idea manifests itself in the subjective function of participants of an interaction who reconstruct social contexts in the course of the interaction on the basis of symbolic meanings. The conducted survey is a diachronic measurement with statistical time series of the years 1988 ¿ 1998 ¿ 2005 ¿ 2017. The survey uses the research tool in which dimensions were primarily established by Charles Glock and Rodney Stark and a community component by Ohio Fukuyama. The term ¿global profession of faith¿ was introduced by French sociologists Louis Dingemans and Jean Rémy to describe motivation and dynamics of changes of one¿s individual religiousness and identification of individuals with religious group of reference. In this survey of social and religious attitudes of young university students, religiousness dimensions adopted by forms of activity on the Internet were added to the research tool.
