RELEX, an internal centre of excellence in research, investigates how socially excluded people view and relate to religion on a cross-cultural scale using a new mixed-methods framework specifically developed for this purpose. Research is conducted in Ghana, Finland, India, and Peru. In each context, our empirical research focuses on the religious views of persons subjected to three particular forms of social exclusion related to: 1) imprisonment; 2) ethnic minority position; and 3) identification as LGBTQI+.
