Christ & Judas
At first glance it might seem something of a pious sentiment when some theologize that the worst part of the Passion for Jesus was the betrayal by Judas. But it does emphasize how seriously Christ took his friendships (i.e. "Greater love hath no man than this, that a man lay down his life for his friends") and that Jesus desired no one lost (...the parable of the Good Shepherd). We tend to think of the Passion in terms of its collective impact, the burden of guilt of all mankind laid upon on his shoulders, but in that tension between the general and particular, the individual and the collective, there is an otherworldly whiff of Isaiah 55:8-9.
