In Arthur Rowe's writing about "Jesus of History, Christ of Faith," he is making a contrast between the scholar's view of Jesus and the believer's view of Jesus. In the 18th century, many scholars were determined to find evidence of what Jesus was really like, but had decided to eliminate the accounts of unrealistic miracles.
Conversely, the "Christ of Faith" refers to the Jesus Christ that true Christians have always believed in. Believers say that Jesus Christ did indeed perform miracles, was a supernatural being, was the Son of God himself, and that faith in Him is the only way to eternal life. While scholars were trying to show the "real" Jesus through science and history, the Christ of faith, His deity, and His ability to work miracles were never doubted by any of His followers.
