Using the example of the Catholic Church in Papua New Guinea (PNG), I detail how, through praxis, it has brought to life a living theology of HIV and AIDS. In this way, the Catholic Church in PNG is responding faithfully to the epidemic. As a Christian country with a generalised HIV epidemic, where the body of an individual is reconstituted through the liturgical practices of baptism and Eucharist, theologically, in PNG the body of Christ has AIDS. In order to examine the ways in which the Catholic Church in PNG has responded faithfully to the Christian body with AIDS, I do so in relation to the three theological virtues of faith, hope and love.
