I was asked to provide a list of "Top Ten List of Books I Think Catholics Should Read" for a new site called Tiber River: Your Guide to Catholic Books. It is a project of Aquinas and More Catholic Goods: one of the leading Catholic online booksellers. Here's what I came up with.
All of these have been hugely influential in my own life, and I think they are very important books, that would be of spiritual and educational benefit for anyone (though the Cardinal Newman titles are quite "heavy" reading and not to everyone's taste). No particular order . . .
Orthodoxy, G. K. Chesterton
Screwtape Letters, C. S. Lewis
The Spirit and Forms of Protestantism, Louis Bouyer
Evangelical is Not Enough, Thomas Howard
The Imitation of Christ, Thomas a Kempis
Essay on the Development of Christian Doctrine, Venerable John Henry Cardinal Newman
Christianity for Modern Pagans: Pascal's Pensees, Blaise Pascal and Peter Kreeft
The Spirit of Catholicism, Karl Adam
An Essay in Aid of a Grammar of Assent, Venerable John Henry Cardinal Newman
St. Thomas Aquinas: "The Dumb Ox", G. K. Chesterton
