The Bible has a very here-today-gone-tomorrow approach to life. We're fragile, vulnerable and like grass in a puff of wind.
One job of a church leader is to have an understanding of risk. In fact that's true in any organisation. People get stewed up about insignificant things and fail to get alarmed by significant ones.
'Yeah, Joan took her mask off for a while but you left chairs blocking the fire escape to tell me.'
If you have had to do a risk assessment you know that you can accept very common minor matters with small consequences but should be ready for uncommon events with serious consequences.
It reminds me of the risk assessment we took of a young people's caving trip. The version that did not go to press said 'If you are unlucky you will get very cold and wet. Normally, everyone is unlucky.' That was the fun bit. We could live with that but were much more careful not to drop young people into fast-moving streams or deep potholes.
These thoughts go through my head when I imagine what it must be like to be a head-teacher in an age of COVID. My prayers are with you. Have a safe term.
