As a child of european jews who survived world war II.. i was steeped in the tradition that survived along with them..
This was a great privilege for me.
My family tree includes great rabbis, such as Rabbi Menahem Mendel Schneerson and Rabbi Abraham Joshua Heschel ("Just to be is a blessing. Just to live is holy.")
Yet it also includes non believers like Karl Marx who also had a great mind and vision. Wasn't the kibbutz movement in Israel motivated by his ideas for "tikkun olam" ?
So how can such disparate cousins be part of one family? ...And indeed all jews are "one family"..
This has led me to the conclusion that tradition should be used to unite -- and not divide -- our people.
