"There is a vast difference between the Christianity of the first century and the [Christianity of today]. To us, Christianity is all too often a code of ethics, a philosophy of life, a standard of performance, but to those first-century Christians, it was a new quality of life altogether, and they did not hesitate to describe this as Christ living in them. Perhaps if we believed what they believed, we could achieve what they achieved. (J.B. Phillips in the introduction of his book, "The New Testament Epistles")
