“…Studies on religion may focus either on the systemic or public sphere (Furseth, 2018b) or on the level of individual religiosity (Allport and Ross, 1967, Glock and Stark, 1965, Jong et al, 1976, Gorsuch and Venable, 1983, Gorsuch and McPherson, 1989, Genia, 1993, Lemos et al, 2019. Individual religiosity is itself a multidimensional concept (Mueller, 1980), but the number and nature of these dimensions are still open to debate (Lemos et al, 2019). The 'believing'-'belonging' paradigm (Davie, 1990) is often adopted as an analytical framework in secularization studies, although some authors proposed that individual religiosity should include three aspects, belonging, behaving, and believing, which must be considered together for defining a unified scale of religiosity (Keysar, 2014).…”
