In a 1951 article titled "A Catholic Looks at Alcoholics Anonymous," author Katherine Neuhaus Haffner wrote:

What is Alcoholics Anonymous? AA is not, as is sometimes supposed, just another temperance movement, a new, fanatical reform crusade. It is a society, operating in groups, that is founded upon spiritual principles, and these principles closely parallel Catholic teaching.

In its reliance on grace, moral inventory taking, its confessional aspect and its emphasis on outreach, Haffner argued, "A Catholic member of AA should be a better Catholic as the result of his affiliation with this society and vice versa."

Still, many are unaware of the role Catholics played in AA's early years, or that one of the key figures was a nun from Ohio named Sister Ignatia Gavin, S.C. (1889-1966). At St. Thomas Hospital in Akron, she helped Dr. Robert H. Smith, AA's co-founder, to dispel the notion that alcoholism was a moral defect, rather than a spiritual, mental and physical disease.

Bridget Della Mary Gavin was one of three children born to a farmer in County Mayo, Ireland. Even as a child, she had what her biographer calls a "raw compassion" for alcoholism:

Whenever I would see anyone under the influence of alcoholism, it actually made my heart sick. I would try to offer everlasting reparation to the Sacred Heart of Our Lord to make up for the offense against His Divine Majesty.

In 1896, the Gavins emigrated to Cleveland, Ohio. An industrial city with a large working-class population, alcoholism was a big problem Parish priests started abstinence societies and young men took a "pledge" not to drink. Bridget graduated from Catholic schools, studied music, and taught music. Although she considered becoming a nun, her mother was opposed to it.

She dated and was even briefly engaged, but the call to religious life prevailed. In 1914, she joined the Sisters of Charity of St. Augustine, a community that ran schools and hospitals statewide. At twenty-five, she was considered a "late vocation" and given the name Ignatia. (Taking a new name signified that a deeper change had occurred in the person entering religious life.)

For many years, Sister Ignatia taught music in Cleveland schools until she suffered a physical breakdown. When she recovered, she transferred to hospital ministry. As her community opened St. Thomas Hospital in Akron in 1928, she was appointed the admitting officer. There she got to know Dr. Robert Holbrook Smith, who, after a bout with alcoholism, had been removed from the rosters of Akron's more prestigious hospitals.

Beginning in 1934, Sister Ignatia began privately ministering to alcoholics with the help of a young intern, Dr. Thomas Scuderi. She tried to treat alcoholics from both a medical and pastoral standpoint, then an unchartered field. Scuderi recalled: "She was a great influence on my life as a physician. She taught me about loving people." However, other doctors (and nuns, too) were less than supportive. Sister Ignatia later wrote:

I recalled very distinctly coming to the chapel for prayer shortly after five one morning, only to be met by the night supervisor who told me in unmistakable terms that the next time I admitted a D.T. [Delirium Tremens] to the hospital, I had better stay up all night and run around the corridors after him.

At a time when chronic alcoholics were routinely sent to mental asylums, Sister Ignatia realized that they needed a healing beyond what medicine could provide. At the same time, she noted, hospitals had "little enthusiasm about admitting people who were imbibing too freely."
