Library content
Our goal is to make A WORLD-CLASS CHRISTIAN LIBRARY which is free for select membership levels. To accomplish this, we intend to stock its shelves with reprints of public-domain Christian books and with content we generate.
We need the help of scholars around the world. Occasionally, a scholar may donate some material and waive copyright. Our bookstore will offer all content for sale, even though it will be available free to those who complete courses and achieve goals. We hope that free books will help motivate the next generation of Christian leaders and scholars. Our goal is to create a world-class Christian Research Portal.
Be compensated for your copyrighted material
We are building our Christian Research Portal, LXON, using a combination of proprietary writings, donated works, and scholastic writings for which we pay royalties. Learn more about our LXONSM business model.
Help us pick which public domain books to republish
There are many important books that are helpful to Christians. We are focusing on works by scholars and theologians. This does not mean we will not eventually publish some of the favorites, like Pilgrim’s Progress. We would like to use our energy to publish books that are no longer readily available. Feel free to make any suggestion you want, and if there is great demand for it, we will reconsider our priorities.
Completed books and papers
Flint, Robert. Agnosticism. Edinburgh: William Blackwood and Sons, 1903.
Our in process list
Bell, B. I. (1931). Unfashionable Convictions. New York and London: Harper & Brothers Publishers.
Fairbairn, A. M. (1902). The Philosophy of the Christian Religion. New York: The Macmillan Company; London: Hodder and Stoughton.
These works are essential for seminarians, historians, and those engaged in high-level cultural apologetics.
Ash-Wednesday
T.S. Eliot,1930
This poem marks Eliot’s conversion to Anglo-Catholicism. It is a profound, scholarly meditation on the struggle of the soul toward God, echoing Bell’s own journey through the “waste land” of modernism.
The Everlasting Man
G.K. Chesterton,1925
A direct challenge to H.G. Wells’ secular history of the world. Chesterton argues that Christianity is not just another “fashionable” philosophy, but a unique, supernatural eruption into human history.
Orthodoxy
G.K. Chesterton, 1908
Perhaps the closest spiritual cousin to Bell’s Unfashionable Convictions. It is a masterpiece of Christian apologetics, defending the “thrilling romance” of traditional dogma against the dullness of secularism.
The Pilgrim Church
E. H. Broadbent (1931)
A monumental history of “independent” Christianity outside the state-church structures. It provides a rare and meticulously researched genealogy of dissenting groups (Waldensians, Paulicians, Anabaptists) that is frequently cited by church historians but often difficult to find in a high-quality, modern edition. It offers an “unfashionable” but vital alternative perspective on church history that resonates with modern “house church” and non-denominational movements.
Christianity and Liberalism
J. Gresham Machen (1923)
The defining text of the Fundamentalist-Modernist controversy. Machen’s thesis—that “Liberalism” is not a version of Christianity but a separate religion entirely—remains one of the most logically rigorous critiques of secularized faith ever written.
The Return of Christendom
Maurice Reckitt et al. (1922)
A collection of essays by prominent Anglo-Catholics and Christian Socialists (with an introduction by G.K. Chesterton). It argues for a total restructuring of society based on Catholic social principles. It is a “lost” classic of Christian political theory that anticipated many modern discussions on “Post-Liberalism” and the “Benedict Option.”
The King’s Highway
G. D. Carleton (1924)
Widely considered the “gold standard” for Anglo-Catholic manuals of instruction. It covers dogma, liturgy, and the interior life with a clarity and firm conviction that is rarely seen in modern “broad” church literature.
Borden of Yale ’09
Mrs. Howard Taylor (1926)
The biography of William Whiting Borden, a millionaire heir who gave away his fortune to become a missionary to Muslims in China, only to die in Egypt at age 25. This is a premier example of 20th-century missionary hagiography. Its “No Reserves, No Retreats, No Regrets” message is a powerful devotional tool for modern youth ministries.
The Catholic Religion 1920s
Vernon Staley
A foundational manual for Anglican and Episcopal members.
A Manual of Church History
F.X. Funk
Originally published in German (Lehrbuch der Kirchengeschichte), this manual became a foundational textbook in seminaries and universities globally. It is prized for its conciseness and objective tone.

Learn about volunteering
We are in the process of building a world-class Christian Research Portal. We want to provide our services and books at the lowest possible cost. To accomplish this, our plan is to minimize expenses by relying on volunteers. We need volunteers in all seven of our departments. To determine whether there is something that interests you, there are two steps you need to take: 1) review the organization chart and startup plan; and 2) go to the department you are interested in to learn more and volunteer. Remember, on the Internet, you can be located anywhere in the world to be part of our team.
