In Acts chapter 8 Philip preaches in Samaria where signs and conversions follow, Simon Magus tries to buy apostolic power and is sharply rebuked, and Peter and John bring apostolic authority. The episode shows the church taking shape and the gospel confronting false motives.

An angel sends Philip to meet an Ethiopian eunuch reading Isaiah; Philip explains Jesus as the fulfillment of the prophecy, the eunuch is baptized, and the story highlights the inclusion of the nations and outcasts into God’s promised inheritance.
