The New Testament shows that Jesus was a Jewish Tzadik. He is not claiming anything like the Christian churches say he is claiming. He is not breaking the Law nor telling others to do so. He is not claiming worship but says openly to worship God alone not him. examples are too numerous for me to go into here.

Someone called him "good". And he answered do not call me "good". Only God is good.

From where do misunderstandings come from? From the same sort of insane religious idiots that abound today that call anyone who disagrees with them as a apikorus  and breaker of the Law, though they themselves are amei haaretz ignorant of the Law.  

[I wrote the above paragraphs in short form because I was tired and it was late over here on this side of the pond. But even so it is hard to know from what point to expand on this topic. In terms of the Law, see the Rosh (Rabbainu Asher) in Tractate Shabat where adding water to soil in not a desecration of Shabat. Also in terms of washing hands there are  two sources for this. One is a decree because of the priests eating truma. If that is the actual law then in fact, it is required always before eating bread. But then it has laws involved with it that few people observe. E.g., the vessel has to be totally dry because otherwise the water on the sides becomes unclean as so as the hand touches it and that water on the hand does not become pure when water is next poured on it.  That is why you see Lithuanian roshei yeshiva dry the vessel before pouring. The other reason is from the Gemara in Chulin [perek 8] מים ראשונים מצווה מים אמצעים רשות מים אחרונים חובה "The first waters are a good deed. The second are allowed. The third are an obligation." Thus the first waters are a good thing to do but not an obligation.

I think a simple reading of the NT will show anyone that Jesus referred to himself as to be a "son of man", [never "son of God"]. And when the idea of "son of God" was applied to him and he agreed  with that, it is not all that different from the verse in Deuteronomy  "אתם בנים להשם אלקיכם אל תשימו קרחה בין עינים למת"  You are the children of the Lord your God, therefore do not make a bald spot between your eyes for a dead person as a sign of mourning" [That is not an exact quote, but anyway you get the idea.]

In Israel many people put on their cars a sign תודה אבא Thank you Father. [That does not refer to their physical father but rather to our Father who art in Heaven. Thus referring to God as one's father in not heresy.
