What Will Be My Vow Name?

This afternoon 3 of my brothers and I decided to go to a Marian shrine near Green Bay, Wisconsin (about an hour and a half away), at the site of an apparition of the Blessed Mother that has been approved as being of seeming credibility.  If you would like to learn more about this shrine and story, check out their website at:

This was especially significant since I am planning to take "Mary" as my vow name.  I do not have a middle name, since am "the third" and my grandfather did not have one.  The vow name will be added to my confirmation name of "Xavier," which I chose in high school since I was impressed with the profound difference he made as a missionary.  However, at the time I did not know he was a Jesuit!  Thus, the full name I will be professing at vows will be, "John Xavier Mary Roselle III." 

Why Mary?  That actually came to me around October of last year, as I further reflected on how necessary Mary will be for this vocation.  In short, I NEED Mary to live this life with peace, joy, and integrity.  Of course, I would say we ALL need Mary to seek to live the Christian life to the full.  Mary is the model of how to love and serve Jesus.  She is the source of so many graces, since she bore God in her womb and continues to be a chosen vessel to bring people to Him. 

Then there is Mary's role in the grace of chastity, to which we are all called, including married persons.  However, the contemplation of celibacy adds another layer to that.  Before entering, a wise person  told me off-hand to see all beautiful women as "icons of Mary."  As an icon, beauty is a window to the Blessed Mother, who is always seeking to support us.
