Today is the Feast of Saint Joseph. The step-father of Jesus, Joseph was the name I took as my Confirmation Name.
As the Sacrament helps to form you again into "a new Creation," you can choose to take on the name of a saint as an intercessor on your behalf.
Here is a list of many potential names as well as background on their lives. If you consider taking on a saint's name, please discuss it with your parents and sponsors and then indicate this in your Letter to the Bishop with an explaination about why you chose that name.
