So who were the first people called Christians in Antioch? Were they all Jews? UNLIKELY.
Why did the Jews despise the Samaritans?
"The Samaritans occupied the country formerly belonging to the tribe of Ephraim and the half-tribe of Manasseh. The capital of the country was Samaria, formerly a large and splendid city. When the ten tribes were carried away into captivity to Assyria, the king of Assyria sent people from Cutha, Ava, Hamath, and Sepharvaim to inhabit Samaria (2 Kings 17:24; Ezra 4:2-11).
These foreigners intermarried with the Israelite population that was still in and around Samaria. These “Samaritans” at first worshiped the idols of their own nations, but being troubled with lions, they supposed it was because they had not honored the God of that territory. A Jewish priest was therefore sent to them from Assyria to instruct them in the Jewish religion. They were instructed from the books of Moses, but still retained many of their idolatrous customs. The Samaritans embraced a religion that was a mixture of Judaism and idolatry (2 Kings 17:26-28). Because the Israelite inhabitants of Samaria had intermarried with the foreigners and adopted their idolatrous religion, Samaritans were universally despised by the Jews.
From these causes arose an irreconcilable difference between them, so that the Jews regarded the Samaritans as the worst of the human race (John 8:48) and had no dealings with them (John 4:9). In spite of the hatred between the Jews and the Samaritans, Jesus broke down the barriers between them, preaching the gospel of peace to the Samaritans (John 4:6-26), and the apostles later followed His example (Acts 8:25)."
