(Review of the original, unrevised edition.)
As an outsider to the Lutheran tradition, I found Spirituality of the Cross to be an accessible, enjoyable introduction to Lutheran spirituality and life. Rather than taking an approach that is primarily theological, Veith Jr. walks through some of the more spiritual and practical implications of the beliefs of Lutherans on various topics. This isn't to say that the book is devoid of any theological discussion, but instead that most of the conclusions drawn involve application in our spiritual life.
Veith offer great criticism of the various ways the world seeks perfection, enlightenment, and spirituality, and demonstrating the Bible's challenges to them. I resonated a great deal with a lot of what was said, such as personal reliance upon the means of grace to strengthen our faith, increase our assurance, and to see them as acts of God working in us. While our beliefs regarding the specifics of how this is carried out may be different, I still appreciated the sentiment expressed. His words on bearing our cross are equally powerful. The sections on vocation and the two kingdoms provide a clear framework for our view or our place in the world. Much more could be said.
I did experience some awkwardness, however, in the moments where it was implied that some of these ideas were distinctly "Lutheran", and the issues were framed as "Lutherans vs. the rest of Christianity". Ultimately, credit for our doctrinal convictions should be given to the Word of God itself, and not to our traditions, as if it's our own invention. Veith doesn't say any of this outright, but it was hard for me not to get this impression at times. Calling Lutherans the "first evangelicals", while historically accurate, almost undermines the testimony of New Testament church. Were they not as committed to the gospel as the Protestants, if not more so?
Despite this, I'd still give the book a hearty recommendation for anyone interested in an introductory approach to spirituality from a Lutheran perspective, although, don't solely take my word for it, but from Lutherans as well.
