"When Jesus condemned "traditions of men" he was talking to Rabbis and the issue was Rabbinic law."

You are referring to Matthew 15 and another recounting of the same event in Mark 7, in which Jesus addressed the scribes and Pharisees. The example he specifically used is the issue of preventing honoring father and mother by appealing to a tradition, and in general his objection centered on traditions of men which violated G-d's word. Notice that Jesus backed up his claim by a quote of Isaiah 29:13. This does not contradict the admonition to obey those who sit in Moses' seat as interpreters of the law. I take it that the traditions of the elders were more like customs that had developed, much like other customs of Jews today like breaking a glass at a wedding. And notice that Jesus did NOT tell his disciples that they could not do those customs of the elders like washing hands. The harsh response of Jesus was to those who would condemn his disciples for neglect of elders' traditions in small issues like popping some food into the mouth without washing first, while at the same time condoning major violations of the written law.

"Christianity has NEVER believed in following Pharisee legislation, so Jesus' exhortation to follow the Pharisees is not worth the paper it is printed on."

What "Christianity" does or does not do has no personal relevance to me. I am a Christian in the original sense of the term, but do not consider myself to be a member of any religion called Christianity. Jesus' exhortation is worth a great deal to those who follow him, and it was specifically directed to Jews, and is why many Jews who have come to believe in Jesus have continued to maintain those Jewish traditions that are, in their estimation, in line with the written Torah. You call it "being deceitful", "pretending to be Jews when they are not".

"Christianity by definition can never follow Jesus' orders. Since Christianity claims the Sanhedrin judged against him, how can Christians obey the Sanhedrin?"

As long it didn't directly contradict the word of G-d, they would and did. However, one might consider that especially today, not anyone that studies to be a rabbi might be really sitting in Moses' seat.

DanFTL, so you think that you can have all the premarital sex you want, as long as the woman had sex before? It seems to me that this woman who had sex before was supposed to be already married to that first man. I think that you are watering down the commandment. It doesn't seem to be an option offered for the man or woman, but only for the father of the woman. Are you keeping the law, or are you not?
