Was the water troubled by an angel? Possibly, what apostles and theologians call an angel a scientist knows as carbonic acid gas.
John does not say that the people thought the water was troubled by an angel, but he states it as a fact. And he tells us, also, as a fact, that the first invalid that got in the water after it had been troubled was cured of what disease he had.
What is the evidence of John worth?
Again I say that if the Devil does not exist the gospels are not inspired. If devils do not exist Christ was either honestly mistaken, insane or an impostor.
If devils do not exist the fall of man is a mistake and the atonement an absurdity. If devils do not exist hell becomes only a dream of revenge.
Beneath the structure called "Christianity" are four corner-stones—the Father, Son, Holy Ghost and Devil.
IV. THE EVIDENCE OF THE CHURCH.
The Devil, was Forced to Father the Failures of God.
All the fathers of the church believed in devils. All the saints won their crowns by overcoming devils. All the popes and cardinals, bishops and priests, believed in devils. Most of their time was occupied in fighting devils. The whole Catholic world, from the lowest layman to the highest priest, believed in devils. They proved the existence of devils by the New Testament. They knew that these devils were citizens of hell. They knew that Satan was their king. They knew that hell was made for the Devil and his angels.
The founders of all the Protestant churches—the makers of all the orthodox creeds—all the leading Protestant theologians, from Luther to the president of Princeton College—were, and are, firm believers in the Devil. All the great commentators believed in the Devil as firmly as they did in God.
