I think it's very interesting to look at how one's practices one's faith vs what the main teachings of one's faith actually say. I am not getting on one side or the other, I just think that it's interesting. A lot of faith splits happen based on the interpretation of teachings and the following after one type of leader.
Sabbath Traditions: I see them in the light of "Fiddler on the Roof" (sorry) in that sometimes a persecuted people group must find things and traditions to hold onto. I personally like the symbolism of the white candles and the braided bread- more than I need to understand the history. That being said, things can get tricky if you're trying to determine which parts of your traditions are prescribed and by whom. I do not envy you your search.
Jesus's Sabbath: I am no scholar for the era, but I would guess that He probably didn't have the candles or the bread. Perhaps they are more ancient than I think? The expectation of a Sabbath during Jesus's time was one of rest. Biblical scholars say that there were rules in place to govern what types of work could be done. Also, how far one was allowed to travel.
Here are some examples that I found about how Jesus treated the Sabbath:
Jesus heals the lame man
healed a
man born blindpicking grain on the Sabbathdrived out a demon (in the synagogue)
healed a crippled woman
It appears that Jesus considered Sabbath as another work day. He pronounced Himself the "Lord of the Sabbath" several times. I have enjoyed thinking about this subject, because I had never spent any time reading about all the places where Jesus "broke" the Sabbath.
Good luck in your quest.
