Acts 10:37

Peter proceeded to outline Jesus of Nazareth’s career for his listeners assuming some knowledge that was common but adding more details than Luke recorded in Peter’s previous speeches. This is the most comprehensive review of Jesus’ career found in any speech in Acts. These details would have been appropriate since Peter’s hearers here were Gentiles. Peter’s sketch followed the same general outline as Mark’s Gospel, which, according to early Christian tradition, Peter influenced.

Luke undoubtedly summarized Peter’s message, as he did the other addresses in Luke-Acts, and stressed points important to his readers. These points included the fulfillment of Isaiah 61:1 (in Acts 10:38, cf. Luke 4:14-30), the importance of apostolic witness (in Acts 10:39-41, cf. Acts 1:8), and Jesus’ post-resurrection eating and drinking with his disciples (Acts 10:41, cf. Luke 24:41-43). "The thing" to which Peter referred was the earthly ministry of Jesus.
