Dr. Ludwig Ott
Fundamentals of Catholic Dogma by Dr. Ludwig Ott is the definitive one-volume encyclopedia of the doctrines of the Catholic Church, showing their sources in Scripture and Tradition and their definitions by Popes and Councils.
Dr. Ott defines theology, moves on to dogma, then moves on to the development of dogma, Catholic truths, theological grades of certainty, and theological opinions. From that point he goes on to systematically and exhaustively review all of the Catholic dogmas.
This is a book no serious student of the Catholic faith should be without!
