The Haydock New Testament is a larger-print (12 point) format Douay-Rheims Catholic Bible with a comprehensive Catholic commentary (210 sources used!) and an illustrated Catholic Bible Dictionary and History of the Books of Holy Scripture reproduced from the 1859 edition of Fr. Haydock, whose superb explanations and commentary take up about one-half to two-thirds of each page. The commentary is drawn largely from the Fathers and Doctors of the Church.
A nineteenth century Roman Catholic priest, pastor and Bible scholar, George Leo Haydock is most famous for his edition of the Douay Bible with extended commentary, originally published in 1811. It became the most popular English Catholic Bible of the 19th century on both sides of the Atlantic. Fr. Haydock served missions and chapels in rural England.
