Can anyone withhold baptism? Reflection on Acts 10:47-48

In this passage from Acts, baptism is preceded by the receiving of the Holy Spirit. But, in Acts 8:14-24, the Samaritans were baptized before receiving the Holy Spirit.

I don't think that which came first is as important to Luke as that they both do, and, even more important, that they both come to people that the rest of us might not have thought likely or even worthy.

Methodists believe baptism is the beginning but not the end. See this overview of the United Methodist  understanding of baptism.
