Religious Studies
Religious studies, alternately known as the study of religion, is an academic field devoted to research into religious beliefs, behaviors, and institutions. It describes, compares, interprets, and explains religion, emphasizing systematic, historically based, and cross-cultural perspectives.
Theology
Theology must be man's critical reflection on himself, on his own basic principles. Only with this approach will theology be a serious discourse, aware of itself, in full possession of its conceptual elements.
Gustavo Gutiérrez, A Theology of Liberation (1971), p. 11.
