There's a story that may give us some insight into this weekend's  celebration of the Most Holy Trinity.

It seems that there was an elderly Bishop  who was celebrating the sacrament of Confirmation in a parish in his diocese.  The Bishop knew that he was losing his hearing, and really didn't like wearing the hearing-aids the doctors had given him, but he continued to do Confirmations anyway.  He had been a Bishop for a long time, and he liked to ask the candidates questions about their knowledge of the faith before he did the Confirmations.  He wanted to see if the candidates were adequately prepared.

At this particular Confirmation, the Bishop proceeded to ask his questions of the candidates, and he started with a question about the Trinity:  "Who can explain our doctrine of the Trinity?"

A young lady in the first row sheepishly raised her hand and answered: 'The Trinity is our belief that there is one God, with three persons, Father, Son, and Holy Spirit."

The Bishop, because he wasn't wearing his hearing-aids, couldn't quite hear the young theologian's answer, and so he said, "I'm sorry, I don't understand what you said."

The young girl responded, "It's OK Bishop, it's a mystery.  You don't have to understand it to believe it."
