Fulton Sheen once said, “There are not over a hundred people in the United States who hate the Catholic Church. There are millions, however, who hate what they wrongly believe to be the Catholic Church—which is, of course, quite a different thing.”
This statement is, if anything, even truer today. For the past twenty-five years, I have been involved in the work of evangelizing the culture and have seen this reality firsthand. I have encountered many people who harbor an enormous antipathy toward religious belief in general, and Christianity in particular. And what has become crystal clear to me in that time is that the overwhelming majority of these critics do not have a firm grasp of what the Church actually teaches.
What Christians Believe: Understanding the Nicene Creed, an abridged version of my book Light from Light, is intended to address precisely this problem. The Nicene Creed is an ancient statement of faith that has guided Christian thought, both East and West, down the centuries, uniting believers across traditions and generations. As such, it serves as a fitting overview of the Christian faith, especially in 2025, which marks its 1,700th anniversary. In What Christians Believe, which features a foreword by theologian Matthew Levering, I walk readers through the Nicene Creed line by line, explaining its teachings on the mystery of the Trinity, the saving mission of Jesus Christ, the life of the Church below and the life of the world to come, and more.
Today, more than a quarter of Americans claim no religious affiliation at all. In a number of studies undertaken within the past decade, people who have left the practice of religion were asked why they disaffiliated. They gave various reasons, but one of the most prominent was simply that they no longer believed in the teachings of Christianity. This book, which tries to explicate those teachings in a compelling way, is written especially for those who have wandered away from the faith.
I would humbly ask that you read and share this little book and consider ordering a copy for your parishioners, your family, or your friends. May we, as a Church, work to clarify what Christians believe to nonbelievers, and fortify what we believe in our own hearts.
Thank you, and may God bless you,
Bishop Robert Barron
