The major research with a theological and developmental psychological perspective on the meaning and development of faith has been produced by James Fowler of Emory University and the Candler School of Theology. In this paper, I will present challenges by important critics who pose a significant question. Is this faith of the faith development research Christian faith? To provide an initial answer to the question, I will offer brief summaries of some of Fowler's writings that he has listed as most important for responding to the question. I will also present evidence from his writings and from the writings of other authors that he is indeed interpreting Christian faith.
