A History of Christianity is a 1976 study of the history of Christianity by the British historian Paul Johnson. It has since been reissued and updated. The author aims to present a comprehensive factual history of the Christian religion. Contents In the Prologue, Johnson writes: "During these two millennia Christianity has, perhaps, proved more influential in shaping human destiny than any other institutional philosophy, but there are now signs that its period of predominance is drawing to a close, thereby inviting a retrospect and a balance sheet.... Christianity is essentially a historical religion. It bases its claims on the historical facts it asserts. If these are demolished it is nothing.... A Christian with faith has nothing to fear from the facts."
