I wholeheartedly agree with the diagnosis, as presented in this book. I agree that social media makes us worse people, that correction is best presented in relationship, and that we should think locally.
I also appreciated the kind tone of this book. It was trying to start a dialogue, and was raising questions and trying to offer some solutions, not just pointing fingers or publicly complaining about an issue that the author feels passionately about.
However, I mostly disagree with the prescriptions offered in this book, and I think they are actually the type of thing that people have been trying for a while. We can try the things in this book, but they won't work in all contexts (which, yes, is actually somewhat the author's point). We can teach and try to engage people all we want, but we can't actually make people believe wholeheartedly and commit to their faith and local church. If parents aren't reinforcing Christ at home, then all our efforts in the church, as pastor or people, will still be unlikely to retain youth. Parents need to be committed if we are going to expect any commitment from their children.
I don't think this book explores all the possibilities when it comes to the pastor shortage. I think it's silly that we have so many of our ordained serving in administrative positions at Synod, CPH, CUS, etc. If those positions actually required an ordained man, then those should be the jobs for when pastors retire from the parish. We have a lot of ordained men serving in positions that could be served by theologically educated lay people. Ordained men under 55 should strive to stay in the parish as pastors. And other countries need missionaries, yes, but maybe our pastors shouldn't be recruited in such large numbers to International Mission, if the US is actually the 3rd largest mission field in the world. Clearly they are needed here. Neither of these things were even mentioned in the book. Plus, we have large churches that have 3 or 4 ordained pastors. Youth don't need an ordained man to serve them specifically, so we could spread out some of our ordained clergy by using the raise up from within model for specific youth ministry, if that's even an appropriate thing to do anymore. Youth should be encouraged to join with the adults in their Bible study and volunteer service, especially if having relationships across the generations helps with youth retention.
Also, if a man feels called into the Office of the Holy Ministry, why is it unreasonable to ask him to overcome the "bottlenecks" as listed in this book? Maybe SMP needs more scholarships, but pastors in the LCMS are expected to be able to take any Call throughout the Synod. So moving across the country shouldn't ever be considered a barrier. I know this world is expensive. But my family has moved around the US to accept a Call 3 times. It can be done. Christ and His Church take care of pastors and their families.
No one "owns" any part of ministry, and serving in the church doesn't have to be teaching oriented. We don't want people serving because they get an ego stroke from it, which makes them feel important. Yes, we want people to be committed and involved in the work of the church, but that should not be framed in language of ownership. It is Christ's Church and His ministry.
Also, Bible study is part of Word and Sacrament, and so are shut-in visits (since the pastor is bringing Jesus through Word and usually Communion to a person who is incapable of coming to Divine Service). We should not be passing those roles off to others. Those parts are the pastor's responsibility. And if we think that that type of service is the only type that fulfills ministry, then we are returning to a Medieval view of vocation, which Luther very strongly spoke against. The Christian garbage collector does as much of a good work for the sake of the community as does the one who preaches and teaches God's Word. Let's not lose our robust teaching on vocation.
This book also needed a proofreader. There were lots of times where there was an extra word or a word missing in various sentences.
