I would highly recommend this book not only to people who are interested in an introduction to Lutheranism, but to those who fail to understand High Church culture in general. Cooper demonstrates for us that not only is highly Liturgical Worship historical, but it is deeply grounded in what we see in worship throughout the continuity of the Old Testament and New Testament.
If anyone was to say to me, as many have said before, that High Liturgical churches are just about "going through the motions and not having any heart," then I would simply just reiterate the arguments from this book and recommend it to that person. Though that line of argumentation come off as silly, it just goes to show that a book like this needs to be read not just by Lutherans, but by American Evangelicals as well. Not even necessarily to convert them, but merely just to bring understanding in the midst of what is often sheer, unmitigated ignorance about High Church culture. Everything in the Divine Liturgy has deep theological meaning. If you don't get it, then you need to take off your sandals and seek understanding with wonder, rather than starting from a posture of criticism. Once you understand, then you are free to decide if you should be attending High Liturgical church or not.
