 Nine editions of "Moral Theology" were published during the author's lifetime, the first of which was released in 1748 and consisted of annotations on a treatise called "Medulla Theologiae Moralis" by Hermann Busenbaum, a 17th century Jesuit theologian.After the 8th edition in 1779, Alphonsus considered his work definitive, and in 1785 the ninth edition finalized the book's contents.Since his death, many further editions have been published, including a partially completed English edition from Mediatrix Press, the first volume of which was released in 2017.
