2020 Facsimile of the 1925 Edition. Originally published in 1918 as Apologetics as Volume One and then followed by Volume Two, Catholic Doctrine, this is a standard high school Catholic curriculum for the faithful. Often published as two volumes in one, our edition reprints only the volume on Apologetics. Review: "Almost 500,000 copies of this classic high school text were printed, which was used to teach the Faith to generations of English-speaking Catholics around the world for more than four decades. Its outstanding clarity, persuasiveness and comprehensiveness are totally unique... For years, this book gave to many young Catholics the support and knowledge to sustain their Faith throughout their lifetime. They knew the Catholic Religion, and they knew the reasons for it. Both teachers and students who used it have testified to its lasting impression upon them." From Baronius edition of the two volume edition.
