The primary source of the appeal of Christianity was Jesus - His incarnation, His life, His crucifixion, and His resurrection.

The most that one of Jewish faith can do - and some have gladly done it - is to say that Jesus was the greatest in the long succession of Jewish prophets. None can acknowledge that Jesus was the Messiah without becoming a Christian.

Freedom was conditioned by man's physical body, heredity, and environment.

As the centuries pass, the evidence is accumulating that, measured by His effect on history, Jesus is the most influential life ever lived on this planet.

Christianity emerged from the religion of Israel. Or rather, it has as its background a persistent strain in that religion. To that strain Christians have looked back, and rightly, as the preparation in history for their faith.

We know something of the history of the spread of Christianity, but much passed from recorded memory and much was transmitted by tradition whose accuracy has been repeatedly questioned.
