In the pluralised contexts of many contemporary Australian Catholic schools, cultural and religious diversity is a reality that could be ignored or potentially utilised to enhance learning. This case study probes the perceptions of parents regarding their children's engagement in Religious Education in a Catholic school and in particular, engagement in interreligious learning and teaching. The small qualitative study utilised interviews with parents that were analysed and coded to reveal themes that are then discussed in light of the literature reviewed. Four key themes emerged: engagement, diversity, voice and agency, and identity revealing potential for enhancing partnerships with parents and families in the educative project of growing young Australians into their humanity and working towards the creation of a civilisation of love. The study points to a potential for the 'wider Church' to engage families in dialogue through articulating the why and how of Religious Education in Catholic schools (including interreligious learning and teaching) and enhancing parental engagement in such learning and teaching to resource the spiritual/religious identity of all as they grow into the fulness of life.
