“The central mitzvah or commandment for our era is the mitzvah of Tikkun Olam. It is the defining mission of Jews to strive for the repair of the world by making society more just, fair, egalitarian, and sensitive. Judaism demands that we repair the world by striving for social justice. It is the mission of Jews in the Divine Plan for the universe to repair the world by repairing man, by improving and advancing mankind.”
The above paragraph is a fair representation of what has become the defining raison d’etre of Judaism as conveyed by non-Orthodox liberal Jewish organizations and synagogues in America. It is not a direct citation from any of them, but is an accurate paraphrase of what has become the canon of non-Orthodox Jewish liberalism in our time.
