As someone who is no longer Catholic, I still wonder who everyone's Confirmation saint is. I think this is only a Catholic thing, so a lot of non-Catholic Christians may not understand this.
My Saint is the angel Gabriel. I chose him because my mother's name is the feminine version, and also because 11 year old me thought it was so very awsum that he's both an angel and a saint. Sometimes I still wear the pendant they gave me of him, sometimes I wish I never stopped being religious.
