Reasonable Faith

About Reasonable Faith

Reasonable Faith is the online apologetics ministry of William Lane Craig, one of the most prolific and influential Christian philosophers and theologians of the late twentieth and early twenty-first centuries. The ministry's YouTube channel, operating at @ReasonableFaithOrg, has become one of the most comprehensive archives of philosophical Christian apologetics available anywhere online, featuring more than 500 videos spanning formal public debates, university lectures, animated explanations of philosophical arguments, Q&A sessions, and recordings of Craig's Defenders class, an ongoing adult Sunday school course that has addressed virtually every major topic in Christian systematic theology and philosophy of religion.

William Lane Craig was born on August 23, 1949, in Peoria, Illinois. He earned a Bachelor of Arts in Communications from Wheaton College in 1971, a Master of Divinity from Trinity Evangelical Divinity School in 1975, a doctorate in philosophy from the University of Birmingham in England in 1977 (working under John Hick), and a second doctorate in theology from the University of Munich in 1984 (studying the historical argument for the resurrection). His academic career included positions at Trinity Evangelical Divinity School, Westmont College, and a research fellowship at the Katholieke Universiteit Leuven in Belgium before he joined the faculty of the Talbot School of Theology at Biola University, where he served until his emeritus status. He is the author of more than forty books and hundreds of scholarly articles in philosophy and theology.

The Reasonable Faith Ministry

Craig established the online ministry ReasonableFaith.org in the mid-2000s as a hub for apologetics resources aimed at equipping Christians to engage intellectually with challenges to their faith. The ministry's name derives from Craig's most influential book, Reasonable Faith: Christian Truth and Apologetics, first published in 1984 and revised multiple times since, which has become one of the standard introductory texts in contemporary Christian apologetics. The book argues that Christian belief is not only compatible with reason but can be positively supported by philosophical argument and historical evidence, and the ministry has sought to embody that conviction across all its programs and resources.

The YouTube channel functions as the primary video arm of this ministry, and with over 1,000 hours of content, it represents one of the largest archives of intellectually serious Christian apologetics in video format. The channel is organized around several recurring formats, most prominently the Defenders class recordings, in which Craig teaches systematic theology and apologetics to a live adult audience; formal debate recordings with a wide range of interlocutors; and short animated videos that explain philosophical arguments for God's existence, the resurrection, and related topics in accessible formats.

Philosophical Theology and Key Arguments

Craig is best known for his defense and development of two major arguments. The first is the Kalam Cosmological Argument, a medieval Islamic argument (originally developed by al-Ghazali) for the existence of God based on the premise that the universe had a beginning, which Craig has updated using modern cosmology and defended in numerous academic publications and debates. The argument holds that whatever begins to exist has a cause, that the universe began to exist, and that therefore the universe has a cause that is uncaused, timeless, spaceless, and enormously powerful, which Craig identifies with the God of classical theism.

The second is his comprehensive historical case for the resurrection of Jesus, which Craig has developed across many books and lectures. His argument draws on three historically established facts, which he argues require explanation: the empty tomb, the post-mortem appearances of Jesus to individuals and groups, and the origin of the disciples' belief in the resurrection. Craig argues that the best explanation of these three facts is the actual resurrection of Jesus, and this argument has been the centerpiece of many of his most-watched public debates.

Beyond these signature arguments, the Reasonable Faith channel addresses an extraordinarily wide range of philosophical and theological topics, including the nature and attributes of God, the problem of evil and suffering, divine foreknowledge and human freedom, theories of the atonement, the historical reliability of the Gospels, the nature of space and time, the anthropic fine-tuning of the universe, moral realism and its relationship to theism, and the nature of human persons. The Defenders class recordings in particular provide a multi-year curriculum in philosophical theology unmatched in its scope and rigor among online Christian educational resources.

Public Debates

Craig is widely regarded as one of the most effective public debaters in contemporary Christian apologetics, and the Reasonable Faith channel archives a large collection of his formal debates with atheists, agnostics, and scholars representing alternative religious traditions. His debate partners have included Christopher Hitchens, Sam Harris, Lawrence Krauss, Peter Millican, Daniel Dennett, Bart Ehrman, and many others. These debates, often held at major universities in North America, the United Kingdom, and elsewhere, have attracted audiences of hundreds and sometimes thousands and have been viewed millions of times on YouTube.

Critics have noted that Craig is a highly skilled dialectician whose formal debate performance does not always reflect the full state of academic discussion on contested questions. Supporters respond that his debates have exposed millions of people to rigorous philosophical argumentation and have demonstrated that Christian theism can be defended at the highest levels of intellectual seriousness. Whether one agrees with his conclusions or not, these debates represent a significant cultural phenomenon in the popularization of philosophy of religion.

The Defenders Class

One of the most distinctive and valuable resources on the Reasonable Faith channel is the archived recordings of Craig's Defenders class, a comprehensive, multi-year course in Christian systematic theology and apologetics. The class addresses doctrines ranging from the existence and attributes of God, through the Trinity, the Incarnation, the Atonement, creation, anthropology, and eschatology. Each series runs for months or years and engages with both the biblical data and the philosophical and theological debates surrounding each topic.

The verse data for the Reasonable Faith channel reflects this systematic theological focus, with Genesis, Romans, and 1 Corinthians heading the list of most-referenced books. This reflects Craig's engagement with creation theology, Pauline soteriology, and resurrection apologetics, the three areas that receive the most sustained treatment in the Defenders curriculum. The channel is an invaluable resource for Christians and non-Christians alike who want to engage with the strongest contemporary philosophical and theological arguments for Christian theism.

Audience and Influence

The Reasonable Faith channel serves a primarily evangelical Protestant audience, though Craig's philosophical arguments have attracted significant attention from Catholics, Orthodox Christians, and even some non-Christians who find the philosophical questions independently interesting. His influence on a generation of Christian apologetics students, philosophers, and theologians has been substantial; many of the most prominent younger Christian philosophers and apologists in the English-speaking world cite Craig as a significant intellectual influence. The channel represents the most comprehensive available archive of Craig's public intellectual work and offers one of the most rigorous introductions to philosophical Christian apologetics available anywhere.
