Thanks to Holger Szesnat for drawing my attention to this journal:
Word and World
This quarterly journal of theology is based at Luther Seminary, St Paul, MN, USA and it is "meant for readers throughout the church who are concerned for Christian ministry in and to the world". There is detailed information and full text availability on many back issues, all of which are helpfully indexed by theme and author. There is lots of interesting material here and I hope to draw attention to some of the interesting articles in the near future. But in the mean time, do browse around it. I've also added it to my Journals page.
