Deacon Greg Kandra has an excellent homily from this past Sunday posted on his blog. It focuses on St. Paul, here is a quote:
"At this moment, Paul – still known as Saul — was a fresh convert to the faith, newly arrived from Damascus. As the account makes clear, many Christians were afraid of him. They knew his reputation – a persecutor, a Christian-hunter. It’s fair to say that, among the Christians in Jerusalem Paul probably wasn’t the most popular kid at the lunch table. Understandably, nobody trusted him.
But one person saw something more."
