When I was going through RCIA in a (at the time) liberal parish we were discouraged from picking a saint’s name for our confirmation, so I didn’t choose one then. But, I have chosen a few saints for my patron saints for various needs and aspects of my life.
I chose St. Catherine Laboure as my confirmation saint (strictly personal, but not official) because Our Lady was instrumental in leading me into the Church and St. CL was the visionary of the Miraculous Medal apparitions and I share a version of her name.
I chose St. Bernadette because the apparitions of Lourdes drew me into exploring Marian theology and devotions, which was a part of the process that brought me into the Church.
St. Dypmhna helped me recover from the effects left over from my days in a cultish Pentecostal sect, so she is one of my patronesses.
St. Michael came to my rescue at the request of Jesus and Mary to deliver me from a demon sent by Satan to oppress me. So, the Archangel Michael is my champion and the guardian of my salvation.
I was received into the Lay Carmelite Order on May 5th, which is the feast day of St. Angelus, a Carmelite priest, convert and martyr. He has been the guardian of my Carmelite vocation ever since.
And, last by by no means least, St. Therese of Lisieux who is the patroness of my Lay Carmelite community and my guide in living the Rule of St. Albert according to her “Little Way.”
