There is a rabbinic tradition that Abraham and Sarah were so welcoming that they would leave their tent open on all four sides in order to welcome strangers. [1.] So it always amuses me when Rabbanite Jews discuss which Jewish thoughts are not welcome in their modern tent.
Just this week, Rabbi Jack Abramowitz wrote a very good and thought provoking piece on who is “in the tent.” And today, I invite him into my tent, even though he won’t welcome me into his.
