In a recommended booklet titled, Matt Tablot: Hope for Addicts (2002 ed), Fr. Morgan Costelloe, the long-term Vice-Postulator of the Cause of Matt Talbot, briefly discusses Matt's recovery approach from the perspective of the twelve-steps of Alcoholics Anonymous, which was founded a few years after Matt's death.
A more detailed resource about the 12 steps from a Catholic and biblical perspective has been published by Fr. Emmerich Vogt, O.P. Each of the twelve steps is clearly explained in a separate pamphlet. The content of the "Step One: We are Powerless" pamphlet can be read online at
