The content in short: Process theology views God not as a Being, but as a Becoming. In doing so process thought brings into account some of the issues classical theism. For instance, how can an unchanging God let the pleas of both Abraham (about Sodom) and Moses (about the Israelite people) change his mind? There are some assets with process theology, but my evaluation is that process thought trows away the child with the bath water. What I read, presents an impersonal God – and that while God being Personal is one of the key features of Christianity.
