The Bull Ineffabilis, In Four Languages: Or The Immaculate Conception Of The Most Blessed Virgin Mary Defined is a book written by Ulick J. Bourke in 1868. The book discusses the Catholic Church's doctrine of the Immaculate Conception of the Virgin Mary, which was officially defined by Pope Pius IX in 1854. The book includes the text of the papal bull Ineffabilis Deus, which declared the doctrine, in four languages: Latin, English, French, and Italian. It also provides an introduction and commentary by Bourke. The book is a valuable resource for those interested in the history of Catholic doctrine and the role of Mary in the Church.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
