The aim of the presented study was to diagnose the role of religious engagement in the social attitudes of young Silesians, operationalized on the continuum of closeness vs. openness in three areas: (1) community engagement, (2) approval for religion’s interference in the public space, and (3) accepting Catholic Church hierarchs’ views on problems such as euthanasia, artificial contraception, homosexual relationships and in vitro fertilization. The group defined in the presented study is young (age: 16-19) Silesians from Śląskie (Silesian) Province, for whom religion is one of the fundamental values and is regarded by scholars as the core of their identity (N=567). The results of the study confirm that religious engagement is a significant predictor of a closed social attitude in two out of three areas proposed in the model. Higher religious engagement promotes the desire to incorporate the approved religious principles into the secular space. Religious engagement is also a significant predictor of acceptance of Catholic Church hierarchs’ views on underlined problems. The analysis did not show any significant relationships between religious engagement in community engagement of young Silesians.
