Thanks to the resource link by John Roxborogh (from New Zealand) I’ll be checking out this thesis by Michael W. Goheen ‘As the Father has sent me, I am sending you’: J.E. Lesslie Newbigin’s missionary ecclesiology’ definately sometime soon (for a pdf download click here)
Please get in touch as I am trying to write a biography of Lesslie Newbigin. Mike Goheen’s book is extremely good, though defective in biographical information. I take if you already know George Hunsberger’s work? There is also a dissertation in the University of Birmingham Ronald Orchard Centre( where Newbigin’s papers are deposited) by a Father Kelly. (I can look up the precise details if you are interested) It is an early work (1970s) and is quite important for appreciating newbigin’s ecumenical theology.
