Acts 8.2-25 - ...in Samaria...

Most Christians know about Samaritans from the picture presented in Jesus' parable. To call someone a Good Samaritan today loses the irony of the situation.  In Jesus' day, to Christ's audience, no Samaritan was good. It was an oxymoron, like "military intelligence" or "old news"
During the persecution of Paul, Philip the deacon took the good news about Jesus to the Samaritans.
What do we really know about the Samaritans? They lived north of Jerusalem, in the remains of the divided northern kingdom of Israel.  The original Jews were removed and then repopulated after being attacked by the Assyrians. The ancient historian Josephus said that the Samaritans responded to their circumstances. They had friendly relations with their Jewish cousins when times were good and denied their common ancestry when times were bad.

There are some 800 Samaritans in modern-day Israel.  On Passover, they sacrifice lambs at Mount Gerizim.
