An Italian theologian, b. 28 May, 1696, at Sarravezza, Tuscany ; d. 26 March, 1766, at Pisa. His parents were of the lower class. At the age of fifteen he entered the Augustinian order, and preached with success before he had attained his twenty-third year. He subsequently occupied important offices in his order, i.e. those of general secretary, prefect of the Angelica (the former valuable library of the Augustinians at Rome ), general assistant. He first taught philosophy, then theology, at Sienna, Florence, Bologna, Padua, Rome, and finally (1748) became professor of ecclesiastical history at Pisa. He suffered, in 1762, a stroke of apoplexy which was repeated and eventually caused his death. His literary career was an agitated one. By order of Father Schiaffinatti, his Superior General, he wrote the extensive work "De Theologicis Disciplinis" (Rome, 1739-45), an exposition of the theological teaching of St. Augustine. The book, which appeared in several editions, was vehemently attacked by d'Ise de Saléon (who was successively Bishop of Agen, 1730-35, Bishop of Rodez, 1735-46, and Archbishop of Vienne, 1747-51) and by Languet de Gergy, Archbishop of Sens (1731-53). They accused Berti of Jansenism. In answer, the latter published: (1) "Augustinianum Systema de Gratiâ" (Rome, 1747; Munich, 1750); (2) "In Opusculum" (Leghorn, 1756). The accusations against Berti were submitted to the Roman authorities. Benedict XIV (1740-58) had his book examined and found its teaching sound. Besides other works published in this controversy, Berti wrote: (1) "Commentarius de Rebus gestis S. Augustini" (Venice, 1756); (2) "S. Augustini Quaestionum de Scientiâ . . . . dilucidatio" (Pisa, 1756); (3) "De Haeresibus Trium Priorum Saeculorum" (Bassano, 1769); (4) "Historia Ecclesiastica" (Florence, 1753), an ecclesiastical history, which he later published in an abridged form (Pisa, 1760), and which, thus shortened, was frequently re-edited (recently at Turin, 1892).

The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history. This easy-to-search online version was originally printed in fifteen hardcopy volumes.

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
