Diakonia Studies closes Collins' groundbreaking account on 40 years of involvement in linguistic research and argumentation concerning the nature and functioning of Christian ministry.Dispute has ranged around the Greek term diakonia for 50 years. Once seen as enshrining the New Testament value of loving Christian service - what Murphy-O'Connor called "one of the dogmas of New Testament scholarship" - the word was exposed by Dieter Georgi in 1964 as arguably meaning somethingquite different. In 1974 John N. Collins published his first paper on the issue, pointing to inadequacies in Georgi's brief account, and in 1990 published his extensive semantic survey Diakonia: Re-interpreting the Ancient Sources.Collins' re-interpretation was variously hailed as "devastating," "provocative," "unfashionable," and "a scholarly avalanche whose conclusions are inescapable." Since the review by Hans-Jurgen Benedict in Germany in 2000, the book has been the center of "the Collins-Debate." Meanwhile, Collins'findings have been incorporated in the Danker Greek-English Lexicon of the New Testament.Studies in the second section rehearse in a non-technical way (i.e., without appeal to particulars of Greek) the reasons why theologians need to review not only cherished readings of leading New Testament passages but also reassess what some passages might really be saying about the nature anddelivery of ministry. These third millennium issues are the matter of the final papers, reminding churches of the ministry they have received and of their filed-away commitments to an ecumenically charged ministry. Discussion embraces ordained and lay ministries, the tension between office andcharism, and prospects for deacons when a diakonia of loving service no longer defines their call.
