A worthwhile commentary on the book of Acts. There is much to appreciate about the detail and approach. It essentially moves chapter by chapter by going verse by verse, narrowing in on a section of verses, or utilizing bold type to emphasize some of the main historical/theological/translation/interpretation concerns. Often the bold section tackles an issue that stands much broader than the verse(s) at hand, and this is an element that helps distinguish this commentary in its approach.
The book spends a good deal of time reflecting on the theological significance of baptism in the book of Acts by outlining its historical development. As well it has some great pieces on the dual themes of "the kingdom of God" and "angels", along with the weighty focus on the "spirit" of God. I spent a good deal of time reflecting on the questions regarding the place of "resurrection" in Paul's devotion to the Gospel, including the ongoing tension that existed between the Sadducees and the Pharisees. Does the credibility of the resurrection of Christ depend on there being a resurrection for all, or does the resurrection of all depend on the resurrection of Christ? This is one of the questions that tries to navigate some of the tensions that Paul could have been facing. I also appreciated the attention given to interpretations of the term "righteousness". Here he treads in to some of the thoughts that N.T. Wright has brought in to the foreground in recent years regarding "righteousness" as right standing (as opposed to a moral positioning). Pelikan gives some thought to how the interpretation as right standing can help us view the book of Acts.
One of the most impressive things about Acts is its place as a historical study and intentional apologetic. Near the final chapters Pelikan talks about how the tradition of studying scripture has always held a tension between objective commentary and personal investment. Acts offers us an example of how this tension can be held in good form. As well, within the pages of Acts we see its main characters demonstrating this practically as well as they move from and adapt their message to particular audience and settings. They move with conviction but also with an inherent sense of an inclusive Gospel. Paul is not shy to connect his Christian understanding directly in to the world of Jewish worship, while at the same time sees it entirely at home in a pagan/gentile audience in which the gods of worship remain unnamed. It is in fact the powerful trajectory of Acts as literature from the streets of Jerusalem to Rome that sees the movement of Christianity in a sort of sweeping scope. It is at once entertaining, impressive and challenging.
Pelikan sits decidedly on a Lukean authorship, which has been the common understanding. He does mention that there are some that bring question to this conclusion, but the majority appear to accept the Luke-Acts attribution, and reading Acts through that lens can offer some rich study we might otherwise lose.
