Which is it? He NEVER spoke to Gentiles or there was an exception and He spoke to a Gentile?? You made an absolute statement that wasn't true. For all we know, Jesus spoke to lots of Gentiles.
John 21:25
And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen”
Also, Jesus did a lot of things that were considered "forbidden" or taboo. Such as speaking to the Samaritan woman alone, at the well. Where were his messengers or intermediaries there?
OK...for a more precise description of the things that happened we always go to the Gospel of Luke to see how things really happened. The story of "The Faith of the Centurion" is an example of this...there weren't two different centurions...this is just a retelling of the same story from a more Roman perspective which will include such things as messengers. In Hebrew it is considered "of course" type of information and because of the cost of ink and paper the information is left out. There is some of that "of course" type information left out of Roman style of writing but it is usually a different list of things. (different culture...go figure eh?)
Now the story of the Samaritan woman is different.
Samaritans were Jewish...and if you will let me explain...
Way back when the nation of Israel was divided into two nations and the nation of Aram was harassing the northern tribes of Israel. (which is why everyone spoke Aramaic) The Nation of Assyria rose up and actually were the ones that Conquered the Northern tribes of Israel(as well as Aram). They hauled everyone who was a somebody in Israel back to Assyria to become a slave of the Assyrians. (Judah and Jerusalem and Assyria were later conquered by Babylonians) The ones that were left were the very poor and those who had not recorded their births in the Temple. These people later married the Assyrians and Arameans that were used to replace the Israelites that were taken away as slaves to Nineveh (yes, where Jonah went)
So...when the Israelites came back to occupy the land during the Persian Empire as allowed by Xerces in the book of Ezra and etc those Jews who remained this whole time wanted to worship God too. But the Israelites/Jews didn't want them to use "their Temple" because their parentage was highly in question. And there was a huge racial and religious divide between them. In fact the civil war between the Samaritans and the Jews was so bad that they often fought during things like Passover...which when the Romans caught them they went in and killed everybody. Copies of the Torah also were very expensive...like a person's whole year's salary expensive. And when these Torah scrolls were purchased and paid for they Samaritans discovered that the Jews had deliberately changed the words to keep the "Samaritans" out of Jerusalem during the religious festivals.
But Jesus was not a racist...However under OT law He needed to undergo purification rituals that lasted a week before He was considered "clean" once again from talking directly to people that were "unclean".
So...When I say that Jesus didn't speak directly to the Gentiles...aka Goyim (which is a bad, Yiddish word) I mean just that.
Now...
The show has some good points and some bad points. I do love some of the scenes that they create. But I wish that they were more anthropologically correct with some of the scenes that they portray as well.
I know that a person might come to the conclusion that I hate the show...I don't. But I just want people to be aware that there are some differences between what is portrayed and reality too.
