I am having a busy week of training for the altar servers - a sort of training / retreat morning each day. For some unfathomable reason, parents seemed really quite keen to leave their children at church for a few mornings during the summer holidays!
The training is for those who mostly serve the Ordinary Form of Mass but on Tuesdays we celebrate the Extraordinary Form, so they came on to serve and were marshalled through the Mass, doing most of the serving under instruction at the time. I must say, they were very attentive and watched avidly. Their opinion afterwards among the typical 12 year old... "The time went very quickly."
So it seems that silence, unfamiliar ritual and the Latin language are not the cause of boredom for children at Mass after all.
I never doubted it!
