On the first Sunday of July every year, Australian Roman Catholic parishes commemorate National Aboriginal and TSI Sunday. This paper explores issues pertaining to this celebration especially: (ii) the norms of liturgical inculturation for the celebration of Roman Catholic liturgy since 1963; (ii) the recently established special celebration on this Sunday; (iii) pope John Paul II’s address in Blatherskite Park, Alice Springs, 1986, to indigenous Australian peoples; (iv) an evaluation of a selection of specially produced liturgical resources for parishes to celebrate this Sunday; and (v) final questions and possibilities for future celebrations.
