The Picts had to decide which Christian church to follow, the Columban or Northumbrian. There were differences between the two, for example, the way in which monks shaved their hair, the designs of churches and crosses, and how each religion was practised. The Picts chose to follow the Northumbrian church, which led to tension and fighting with the Scotti. The Picts ended up taking control of some of the Scotti kingdom.
Pupils could be asked to draw a Columban monk and cross and a Northumbrian monk and cross, in order to reveal their differences. Ask them to list similarities and differences between these two churches. Compare the differences that existed between these historic churches with the Christian churches in Scotland today.
