Seelos is ordained a priest at the Redemptorist Church of St. James in Baltimore, MD. He celebrates his first Mass as a priest three days later, on Christmas Day. In a letter home, he tells his family of his prayers during that Mass, “I certainly did include all of you in them and recommended you to him whom I had so closely before me and touched with my own hands… Holy Guardian Angels, tell it to them, so that they can share in the joy, share in my prayers, that I may not have the misfortune to be rejected as an unworthy dispenser of the mysteries of God.”
