This book is meant to be a set of questions to lead young people through a Christian catechism of sorts. My advice? Stick to a real catechism.In the preface, Dr. Kreeft introduces his book by telling parents that their teen children will "listen to wisdom better if it doesn't come wrapped in words of parental authority." The difficulty in this statement is that it assumes your teen children will listen to wisdom from pastors or priests or some other adult. If they've rebelled against parental authority, what reason do we have to believe that they will accept any other authority? What do we do if they reject all authority? My suggestion would be to open the book with a Biblical explanation of God's authority, and that God establishes authority like government and the family for our good. The highest paid film star, the poorest beggar, the most talented basketball player are all under authority to someone. Authority is established by God, not by men, so having a snarky comment encouraging teens that it is ok to NOT listen to your parents I think is probably one of the poorest ways to open a book on teaching Christian catechism. I wonder if Dr. Kreeft has read about King Rehoboam, who listened not to the counsel of the older and wiser men, but listened to his young friends and resulted in the splitting of the kingdom of Israel? (see I Kings 12 and II Chronicles 10-12) I Kings 12:8 But he forsook the counsel of the old men which they had given him, and took counsel with the young men that were grown up with him, that stood before him. A second problem I had with this book was the question about whether a Christian can be in the military. The answer Dr. Kreeft comes up with is not a Biblical answer, but a traditional pacifist answer. Nowhere in scripture is a military man ever condemned for his profession. Jesus himself spoke with numerous soldiers, and never once did he tell them to change their occupations. Dr. Kreeft quotes Matt. 26:52 "For all who take the sword will perish by the sword." as the universal condemnation for anyone involved in the military. Unfortunately, Dr. Kreeft is ignoring the context of the passage. There are several interpretations of this passage, but probably the best one is that Jesus is cautioning Peter, the only disciple who attacked those who came to take Jesus. When I skimmed this book, these two issues leapt out at me. If I cannot trust Dr. Kreeft to properly explain God's authority to a teenager, or to allow him to make a teenager who has hopes of serving in the military that his choice will only result in his death, then why should I trust any of the rest of these questions?
