We did Acts 8 in house church Bible study a couple of weeks back:

So Philip started speaking, and beginning with this scripture proclaimed the good news about Jesus to him. Now as they were going along the road, they came to some water, and the eunuch said, “Look, there is water! What is to stop me from being baptized?”

Well, where to start? This certainly didn’t take place in a church context, and in fact it doesn’t seem like there were any other Christians around. The eunuch hadn’t written out his testimony and shared it publicly. He hadn’t been through a twelve week baptism preparation course. Worst of all, what about Philip? He was an itinerant evangelist; he did not act with the authority of a pastor in an established church.

What would happen in your church if any one of the members shared the Gospel with their friends and then just went straight on and baptised them?

I wonder if Philip caught hell from his pastor when he got home. Or if, as so often happened in the book of Acts, people rejoiced that the word of God had spread.
