I remember my Confirmation. I was sooooo worried about the Bishop slapping me across the face.
And it turned out to only be a little tap on the cheek!
Confirmation? Catholic?
I looked it up. What you call confirmation, we call Firmung. It's something different than the confirmation in protestant churches. In Germany anyway. Catholic children have their holy communion (First Communion) at age 9 and later the "Firmung" (which you call confirmation) at age 11 or 12. For catholics, the First Communion is the big event which is celebrated with friends and relatives. The Firmung is not celebrated this way and many even don't take part in it.
For protestant children, the confirmation is really a biggie. It's at age 14 and it's a rite of passage. As far as church matters go, the children are adults after the confirmation. They can become godparents, they can decide for themselves whether they want to attend religious studies classses at school, they can also quit church altogether.
Apart from the religious aspect, it's also a rite of passage socially. With 14, they leave childhood behind them and become adolescent. This reflects also in legislation; they are now 'of the age of criminal responsibility' (had to look up that expression).
No bishop is needed for confirmation. The local priest does it.
