In a boat, on a lake, Jesus leans over to his disciples and tells them to be very careful. It’s a captain’s safety warning, but it’s not about life vests, and it’s not, as the disciples first thought, about the supplies. ‘Be careful,’ Jesus warned them. ‘Watch out for the yeast of the Pharisees and that of Herod.’ It’s a warning for all who would set sail with Jesus on his mission. But what does it mean?
In a nutshell, the ‘yeast’ is a simple, little idea. But it spreads through a group and forms a culture it changes everything. The yeast of these groups were two different kinds, but both concerned with how to rule the world. Well, how to get everyone to behave.
The little idea of the Pharisees seems to be that ‘You can get people into line by shaming them.’ Point out people’s mistakes, make a public example of a few, and people will be too mortified to step out of line. This idea hasn’t run out of steam, we see plenty of it today. It’s the major weapon of our comedian-prophets who try to reinforce a particular framework of values by lampooning those who don’t share them. People who don’t fully support same-sex marriage are constantly shamed, for example. And does it work? Does shaming transform a society? No. It’s a powerful weapon, but at the end of the day, not an effective one.
The Herodians had a different little idea: ‘You can get people into line by coercing them.’ If you have the political power, you can set the rules and police them, and so just make people behave, punishing those who don’t line up. This is another familiar idea. Many people today seem to think you can shape society by getting the numbers in parliament to pass certain laws – say to legalise or illegalise abortion. But when you get the laws you really want, do you then get the society you really want? No. Coercion is another tool that so many clamber for, but in the end it doesn’t build what you want to build.
Jesus is setting out with his disciples to change the world, but it didn’t – and doesn’t – happen through shaming or coercion. Both of them breed elitism, hypocrisy and resentment. Watch out for those little ideas! As sacred agents, we’re not to use them on others or stress when they’re used against us.
And it all raises the big question: What is Jesus’ yeast? Discuss.
