From Garnel: Avraham Avinu's Torah

An excellent post addressing the tradition that the Avot (Our Fathers [I don't know whether the Imahot/Our Mothers are included by the rabbis]) observed the Torah. 

The Hillel version (standing on one foot):

"The "whole Torah" doesn't mean performing the Taryag mitzvos but rather it means participating in the progression of history in total consonance with God's plans."

This is a worthy response to my perpetual complaint about people obsessing over Avraham serving dairy and meat at the same dinner.
