For the past decade, during my visits to Metropolitan John in Athens, he often shared insights from his forthcoming monograph titled "Remembering the Future." He emphasized that his book is intended for those who accept the fact of the Resurrection of Christ and are interested in the logical consequences that follow from this belief: credo ut intelligam. Throughout our discussions, he encouraged us to examine both the foundations and implications of his groundbreaking assertion that "the future precedes the past" from both logical and ontological perspectives. He maintained that Christian theology represents a hermeneutics of Resurrection, a central theme in this book's inquiry. Based on my experiences with Metropolitan John, this presentation aims to present his overall theological work as a holistic Unified Grand Theory encompassing all aspects of theological inquiry within the horizon of eschatology.
