Christianity is the most popular and influential religion in human history. Launched by Jesus of Nazareth two thousand years ago, the Christian movement currently has more than two and a half billion members. Christians are now located in every country on earth, and they represent the majority of the population in Europe, Latin America, North America, Oceania, and southern Africa. But what exactly constitutes Christianity? What does this religion stand for? What makes Christianity Christian? Why have so many people embraced it?

More than one hundred years ago, a professor at a prestigious German university decided to provide answers to all these questions. He arrived at the university lecture hall a few minutes before six o’clock in the morning when it was still dark outside, and the walk across campus had invigorated him. When he stepped up to the podium, not a seat in the house was empty. Six hundred students (all of them male because women would not be admitted to the university until 1908) and a smattering of faculty colleagues had their eyes fixed on him as he began the day’s address. “What is Christianity?” he asked, and they were counting on him to supply an answer. The year was 1900. The place was the University of Berlin. The speaker was Adolph von Harnack, one of the most brilliant and well-known scholars in the world.

Professor Harnack did not disappoint. He gave them a simple and straightforward answer because, he told them, the gospel itself is simple. Christianity at its purest and best is the religion of Jesus, the message that Jesus himself proclaimed. It focuses on three things: the fatherhood of God, the infinite value of the human soul, and the commandment to love everyone. In a nutshell, that was it. That is the essence of Christianity. Christians had advocated many other beliefs and practices during the movement’s long history, but, according to Harnack, those other things were largely superfluous. The only thing that really matters is Jesus’s core teaching. This is the gospel – the message Christianity has to share with the world – and that gospel (or “good news”) is simple.

Something even more basic was at stake, however. For Harnack, the simple gospel of Jesus is not merely the essence of Christianity, it is the quintessence of religion itself. A humanistic scholar who affirmed the validity of science, Harnack served as the first president of the Kaiser Wilhelm society which later became the Max Planck Society for the Advancement of Science, one of the most prestigious centers for the study of human evolution in the world. Harnack was interested in human origins, and he believed that it is religion – the spiritual impulse that leads people to wonder about the mystery of life and how they are called to live – that makes Homo sapiens into something more than merely smart animals. For Harnack, a proper understanding of the gospel of Jesus was not merely the key to understanding Christianity, it was the key for understanding what makes any of us human. And that is why 600 students voluntarily crowded into a university lecture hall at six o’clock in the morning for fifteen weeks in a row: to hear someone explain who they were called to be as followers of Jesus and who they were as human beings.
