As Pentecostals develop their own approach to theological ethics, the Catholic tradition may
turn out to be their most promising dialog partner. As Pentecostals appropriate their own quirky catholicity bequeathed by Wesley, they have much to learn from the narrative of Catholic moral theology given by Servais Pinckaers in The Sources of Christian Ethics . Negatively, Pentecostalshave already developed some of the same destructive tendencies in their short history that took
centuries for Catholic moral theologians to develop. Yet while the story of Catholic moral theology will at times be a cautionary tale, there is equal potential to shape Pentecostal ethics constructively, as exemplifi ed by Pinckaers, Pope John Paul II and ultimately Herbert McCabe.
