A long long time ago (in the Middle Ages) Christians would draw a cross on their documents. This was a sign of their faith as well as their sincerity and honesty. Once the cross was drawn, a ‘kiss’ would be placed over the cross. This was the sender’s oath. In the early Christian history common people weren’t well rehearsed in reading and writing so this was a simple but sincere method of ‘expressing oneself’ as well as providing a signature.
