Dan, I think you know that Jesus used a lot of metaphor and a lot of allegorical language and drama to prove his points. He was not saying at all that Mosaic commandments are no longer applicable or need to be changed--he was saying that they need to be followed more strictly. Correct me if I am wrong, but I believe that Judaism in all forms condemns lusting after women, needless hatred towards anybody, divorce without reason, etc. In this passage, he was criticizing people for not following Levitical commandments, not saying they need to stop following them or follow new ones--in essence, chastising them for not practicing Torah Judaism.
As for the Samaritan parable, yes, the message is that anybody is capable of a righteous act--but moreover, it is a personal challenge to every person to strive to be righteous towards those in need. It is most certainly not a promotion of Samaritans. Since you insist on doubting me, perhaps you can do an online search for some Christian commentaries on the matter.
However this is really besides the point. People have explained to you that this is not what the NT teaches and you still insist on dragging Christianity into the discussion even in places where it has absolutely no place, such as these two Judenrat kapos who feel sorry for Iran. I can guarantee you that Christians (at least conservative evangelicals) want military action against Iran and other enemies of Israel a lot more than most Jews do, right at this very moment in history. You insisting that the NT means what you think it means to the Christians of this forum would be like Gentiles coming to JTF, quoting Tanachic and Talmudic passages, and lecturing Jews as to what they "really" mean, in their eyes, just like that Fakestinian Christian troll Lisa just brought to my attention. It's very offensive. A Christian cannot be an ultimate authority in what some other religion's religious sources state and vice versa. Please try to understand that next time you make a thread that implies that Christianity or the NT is pro-Israeli national suicide or that Lutherans/Presbyterians are the "authentic" Christians and not evangelical, Catholic, Orthodox, etc. Zionists.
