John W. Loftus earned M.A. and M.Div. degrees in theology and philosophy from Lincoln Christian Seminary under the guidance of Dr. James D. Strauss. He then attended Trinity Evangelical Divinity School, where he studied under Dr. William Lane Craig and received a Th.M. degree in philosophy of religion. Before leaving the church, he had ministries in Michigan, Illinois, and Indiana, and taught at several Christian colleges. Today he still teaches as an adjunct instructor in philosophy at Kellogg Community College and has an online blog devoted to "debunking Christianity." His new book is Why I Became an Atheist: A Former Preacher Rejects Christianity.
In this interview with D.J. Grothe, John Loftus discusses his background as an Evangelical Christian preacher and apologist and what led to his rejection of the faith, including both emotional loss and "lovelessness in the church," and also philosophical arguments and historical evidence that caused him to doubt. He critiques the Christian illusion of moral superiority. He challenges religion with what he calls the "outsider test." He explores whether logic and reason led to his atheism, or followed only after he adopted an atheistic point of view for emotional reasons. And he explains what he does believe in now that he no longer believes in Christianity or God, and the benefits he thinks this new worldview brings him.
