We head back into Mark in our Gospel today and into the thick of Pharisaic criticism. Jesus is asked why his disciples do not wash their hands before eating. To fully understand the Pharisees' charge we take a step back and explore the heart and history of the Pharisaic school of thought. What we find in the Pharisees are Jews zealous for the law of God but fixated on ancillary things, things that inevitably distort their judgment, corrupt their heart, and prevent them from seeing that which they've longed for most: the Messiah who's standing right in front of them.
