You must balance Sermon on the Mount Idealism with the PRACTICAL instructions of Jesus given just a few chapters later when He was sending His beloved disciples out on missionary journeys. Note first that He told them to be SELECTIVE with who they preached the Gospel (Matt 10:5). He also told them, "If anyone will not welcome you or listen to your words, shake the dust off your feet when you leave that home or town. (Equivalent to a curse in those days. Even today if you show the sole of your sandal/shoe to most middle easterners it is taken as an extreme offense.) I tell you the truth, it will be more bearable for Sodom and Gomorrah on the day of judgement than for that town. I am sending you out like sheep among wolves, there fore be SHREWD as snakes and INNOCENT as doves. Be on your guard against men;..." (Matt 10:14-17a) and "When you are persecuted in one place, flee to another." (Matt 10:23a) and "Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword." (Mat 10:34) ALL verses NIV. I could and will show much more if necessary to show Jesus' NON-pacifist behavior and admonitions. In the Sermon on the Mount I believe that Jesus was speaking in idealistic terms; in terms which would shock His listeners and get them to think about all of the Jewish legalistic rules which had them bound all up; bound up in a way that not even a priest or legal scribe were used by Jesus as an example of righteousness in the parable of "Who is My Neighbor?" ("The Good Samaritan") but rather one disregarded and shunned and thought of no more than a dog by the Jews then, a Samaritan. You speak ideally and not realistically and that is fine if you are young. Most of us older folks also went through an idealistic phase in our early lives till we experienced more life.
