“Young nun, former atheist, says ‘Remember your death!'” So reads one headline describing our guest this week on The Cross Walk, Sr. Theresa Aletheia Noble, FSP. Although raised Catholic, Sr. Theresa declared herself an atheist as a teenager. Eventually, though, she made her way back home to the Church, and even became a religious sister with the Daughters of St. Paul. As if that wasn’t interesting enough, though, tune in to hear why Sr. Theresa put a skull on her desk and started Tweeting about death about a year and a half ago.
