Acts 10...

It's interesting that the centurion is already a God-fearing man meaning that in its basic definition, he was a Christian. Centurions were Roman soldiers and was rare for Roman citizens to yet be a believer, although there was another recorded in the Bible before this (e.g. at Jesus' crucifixion). I think this chapter shows the heart of a transcultural person. Someone had to have crossed that cultural barrier to convert this Roman centurion to Christianity. And now Peter comes to confirm that call and allow the Holy Spirit to fall on everyone in that household.
