"What, then," asks the Rev. Prebendary W. A. Whitworth, [258] "was the original gospel of power which overran the world with such astonishing success?" The spread of Christianity is thought by nearly all good Christians to have been marvellous. Was it? That is the question we have next to consider. In the first place, let us see what we are told on this point by recognised theologians. In his book, The Bible in the Church, we are reminded by the learned Dr. Westcott, the late Bishop of Durham, that the dispersion of the Jews exercised a great influence upon the spread of Christianity. "The pagans got the idea of monotheism, while the Jews themselves dropped the idea of a 'kingdom' and substituted a 'faith.'" He also reminds us of the broad unity of the Roman Empire, and of the dispersion of the Jews being co-extensive with its limits, and concludes that "during the lifetime of St. Paul every condition was realised for proclaiming the Gospel to the world." "Without such preparation," he says, "the spread of Christianity would be historically inconceivable, and it is a remarkable example of Divine Providence." Here, then, we have an admission of purely natural causes, and, although the believer may be able to look upon them with reverence, as Providential, he can hardly claim them to be at the same time a witness to the power of the Gospel. Also, we shall see that there were many other natural causes at work, and that among them were some which the pious would be the last to connect with a Divine Providence.
