Ben Azzai said: Run to perform even a minor mitzvah, and flee from sin; for one mitzvah leads to another mitzvah and one sin leads to another sin; for the reward of a mitzvah is a mitzvah, and the reward of a sin is a sin.
In their book, The Jew Within, Arnold Eisen and Steven Cohen write that most liberal Jews approach their religious obligations based on their level of comfort or appreciation for that particular form of observance. Those for whom a family experience is meaningful, which describes most Jews, will observe Passover and other family-oriented religious traditions. Those for whom a prayer experience holds value will find themselves at a synagogue on a more regular basis. Those for whom social action is a central part of religious activity will gravitate towards those kinds of activities and the communities that promote them.
Most liberal Jews, according to Cohen and Eisen, reject the idea that they are commanded to observe, and that in that commandment lies its own obligation. For most liberal Jews, the idea of sacrificing their autonomy to choose those activites that are most relevant to their lives and core beliefs is anathema. To sacrifice one's autonomy, especially to something as amorphous as a religious community, is to give up what is best about being a member of the American experience. It is our ability to choose our particular path, the one that speaks to us, that defines the modern experience, not only of Jews, but of all Americans in the beginning of the 21st century.
The Rabbis, by contrast, neither knew nor would they have understood the centrality and priority of autonomy. What they understood was that there were those who are in a position to command - kings and gods - and those who are subject to those commands. G-d may have given us free will (see Pirkei Avot 3.19), but that does not change the fact that we have been given a command, indeed 613 of them, and that our choice is only whether to obey or disobey the command and the Commander.
The essence of Halacha is the notion that we are commanded in the Torah, both the Written and the Oral Law, and that our only choice is whether we will obey the command. We may, in fact we must, study in order to fully understand the nature and the form of the command. We may understand these commands in a historical, theological or sociological context. We may apply modern notions sensibilities to these commands to observe them in ways that are consistent with our moral and social framework. What we may not do is reject them as irrelevant , unnecessary, or anachronistic. To do so is to reject the very framework of positive historical Judaism, the claim of the Conservative movement. When Conservative Jews choose automonmy over commandedness, Conservative Judaism sacrifices its claim to be a Halachic movement.
As Conservative Jews, we have an obligation that calls out to us. We are commanded to observe. As Ben Azzai says, in doing one Mitzvah, another will follow and that, in itself, is the reward.
