Recent days have shown an upsurge of interest in a small Presbyterian church (the Free Church of Scotland, colloquially referred to as ‘the Wee Frees’) because one of its members, Kate Forbes, is running to replace Nicola Sturgeon as first minister. As a former Moderator of that Church, an honorary role as an ambassador for the movement, it is fascinating, amusing and not a little frustrating for me to watch the ‘expert’ commentators get it so wrong, so often, when they discuss it.
