This is a very welcome new translation and, effectively, a new addition to the Lutheran corpus. Other reviewers have already noted it's true strength: the impressively detailed critical apparatus included with each text, which makes the book not simply a joy to read, but a scholarly contribution to our understanding of central texts in Lutheranism.
One might question the insistence by the editor on using gender-inclusive language when translating texts which do not employ that language historically. Although contemporary theology should, quite rightly, be anti-sexist, one cannot help but wonder whether the hermeneutics of the setting in which the original texts were formed may not have been (mis)read by the editor in the light of our 21st Century concern to be gender-inclusive?
One further, minor caveat I have, is that despite the meticulous typesetting and presentation of the texts, I feel the book will be a little over-priced for most students.
Nevertheless, a good and valuable contribution to Lutheran studies, which should be welcomed by scholars and non-scholars alike.
While the editors and translators have done exceptional work in many areas, including critical apparatus and supplemental material, I'm not sold on the gender neutrality that surfaces in several areas. Much of this seems done to support the idea of women in the pastoral office. Also, the choice of "original" texts is questionable in certain cases; perhaps because later modifications put a slightly different spin on certain issues.
But even if you disagree with either a seemingly pro-feminist agenda (in places) or with the choice of sources, this new edition still sparkles. Reading is easy, both because of the writing and editing and because of a good layout and typeface. Notes are copious and background information is well-integrated.
I still await the "perfect" English language version and won't stop using the Triglotta. However, this newest translation has become my first choice for research and has almost completely supplanted the Tappert edition in my reading and studies.
