Back in the day, when asked as an undergrad to write an essay on that dichotomy I refused, and wrote one called the Jesus of History, the Christ of Faith and the Risen Lord instead. But if I were to write one, I would start with this quote:
The Jesus of History is valueless and unintelligible unless He be experienced and confessed by faith as the living Christ. But, if we would be true to the New Testament, we must at once reverse this judgment. The Christ of faith has no existence, is mere noise and smoke, apart from the reality of Jesus of History. These two are utterly inseparable in the New Testament. They cannot even be thought of apart … Anyone who attempts first to separate the two and then to describe only one of them, has nothing in common with the New Testament.
