Bad Theology

Text for today: Matthew 5 xiii; Luke 14 xxxiv-xxxv

On two occasions Jesus compares His disciples with salt. According to Matthew's gospel, He makes the comparison near the beginning of the Sermon on the Mount, immediately after commanding His disciples to rejoice when they are persecuted. According to Luke's gospel, He rounds on a crowd of hangers-on and, with His usual humility, warns that they must give up everything for His sake and count the cost before they do so. On the first occasion He explicitly calls His disciples the salt of the earth; on both occasions he notes that salt which has lost its flavour cannot be re-salted and is therefore entirely worthless.

As many theologians have noted, Jesus made exemplary use of homely and practical metaphor; and never more vividly than in this case. By comparing His disciples and followers with salt, Jesus combines flattery with the standard blood-and-thunder warnings against straying from His doctrine. As God's chosen, the disciples constitute something of rare and useful substance; but even God's chosen only get a single chance. Persecution is no excuse for backsliding: if they lose their usefulness, their loving Father will neither protect them from temptation nor deliver them from evil, but will trample them into the earth along with those who have disregarded His Son's preaching, or even failed to hear it altogether.

The primary use of salt was as a preservative; hence the Saviour's metaphor piquantly emphasises the disciples' function in the world. They are commanded to prolong the life of flesh that would otherwise rot and become food for God's humbler creatures. Their office is that of kitchen drudges, keeping the world's meat fresh for the approaching fire.
