"Luther on the Reform of Worship" by Helmar Junghans
This article, graciously made available by Lutheran Quarterly, provides an overview of Luther's criticism of Eucharistic sacrifice and his own liturgical proposals. LQ offers a few articles and rotates them so this link may fail. If so, the article may be found in Lutheran Quarterly 33 (1999) 315-333. Please check out this journal for great theology, history, and other issues of contemporary Lutheran concern.
