In terms of the status of a tzadik [saint] and how important it is to be close to him or her in order to achieve the Garden of Eden (or be saved from eternal damnation) seems to be an argument among different people. That is not only do they argue about whom is the tzadik that one should believe in, but even if you get a whole group of people that believe in one particular tzadik, it is difficult to get them to agree on how much one should believe in that tzadik.
Some would suggest a
strong position. That believing in chasidut is everything and
one who does not believe is damned. Others might take weak position.
That it is good to believe, but not so essential as the more radical
opinion.
Then, is the
question: "What exactly is it one is supposed to believe about the
tzadik?" Or who could be considered a valid line of tradition coming
from him? Or who is a valid disciple, and who is a bad disciple?
But if we look at the
Torah itself, we do not find that believing in any tzadik is
essential.
The Torah itself looks
like a very radical kind of Monotheism.
If we look in the Rambam/Maimonides
it seems clear that the Torah was willing to make concessions for
people in order to bring them to radical monotheism. (E.g, service in the Temple was so people don't go and offer sacrifices to idols instead.) It looks
like the opinion of the Torah is pure unadulterated Monotheism and
yet she is willing to make allowances for human frailty.
There is a debate in fact about this. Some people hold that the Torah is already radical monotheism. Others hold the Torah is intending to lead people to radical monotheism but that she is willing to make allowances for people that need help to get there. You can probably think of plenty of examples on your own but let me just mention one that comes to mind right now. Elimelech was the king of the Philishtim (Phoenicians) and he was visited by God in a dream and told to go to Avraham [Abraham] to ask Avraham to pray for him. You could say that it would have been better for him to pray to God directly but God knew he was not going to do so, so he told him to ask Avraham. Jacob said "The angel that has saved me from all my troubles should bless the children." Who was this angel? And would not this count as praying to a Mediator? [And the Rambam considered praying to a mediator is the very essence of idolatry]
