The notion of “Western Christianity” appeared in historical and geographical literature in the 19th century. According to Pew Research Center, Christians were the largest religious group in 2015, constituting 31% of the world population. From the research results of this centre it can be inferred that the world is becoming more and more religious: the number of people describing themselves as religious has increased in the world from 82% in 1970 to 88% in 2013 and it will reach 90% in 2020, as it is predicted in the report. The religious vitality among young people is especially important for the future of Christianity in Western Europe as well as more generally – in Europe. Overall, it can be concluded that religion constitutes an unfamiliar aspect of life for most young Europeans. For the future of Christianity in Europe, mainly in Western Europe, it has a pessimistic overtone.
