This study explores how a group of young British-born South Asians understood and defined their religious and linguistic identities, focusing upon the role played by heritage languages and liturgical languages and by religious socialisation. Twelve British-born South Asians were interviewed using a semi-structured interview schedule. Interview transcripts were subjected to interpretative phenomenological analysis. Four superordinate themes are reported. These addressed participants’ meaning-making regarding “the sanctification of language” and the consequential suitability of “the liturgical language as a symbol of religious community”; the themes of “ethnic pride versus religious identity” and “linguistic Otherness and religious alienation” concerned potential ethno-linguistic barriers to a positive religious identity. Findings are interpreted in terms of concepts drawn from relevant identity theories and tentative recommendations are offered concerning the facilitation of positive religious and ethnic identities.
