Spirit. St. Luke expressly tells us that Stephen was full of the Holy Ghost, and then proceeds to narrate certain verbal inaccuracies and certain slips of memory to prove to us that the presence of the Holy Ghost does not annihilate human nature, or supersede the exercise of the human faculties. Just as in other places we find Apostles like St. Peter or St. Paul spoken of as equally inspired, and yet the inspiration enjoyed by them did not destroy their human weakness and infirmities, and, full of the Holy Ghost as they were, St. Paul could wax wroth and engage in bitter dissension with Barnabas, his fellow-labourer; and St. Peter could fall into hypocrisy against which his brother Apostle had publicly to protest. It is wonderful how liable the mind is, in matters of religion, to embrace exactly the same errors age after age, manifesting themselves in different shapes. Men are ever inclined to form their theories beforehand, and then to test God's actions and the course of His Providence by those theories, instead of reversing the order, and testing their theories by facts as God reveals them. This error about the true theory of inspiration and the gifts of the Holy Ghost which Protestants have fallen into is exactly the same as two celebrated mistakes, one in ancient, the other in modern times. The Eutychian heresy was very celebrated in the fifth century. It split the Eastern Church into two parts, and prepared the way for the triumph of Mahometanism. It fell, too, into this same error. It formed an _à priori_ theory of God and His nature. It determined that it was impossible for the nature of Deity to be united to a nature which could feel hunger and thirst and weakness, because that God cannot be affected by any human weakness or wants. It denied, therefore, the real humanity of the Lord Jesus Christ and the reality of His human life and actions; teaching that His human body was not real, but merely a phenomenal or apparent one, and then explaining away all the statements and facts of Gospel history which seemed to them to conflict with their own private theory. In the West we have had ourselves experience of the same erroneous method of argument. The adherents of the Church of Rome argue for the infallibility of the Pope in the same way. They dilate on the awful importance of religious truth, and the fearful consequences of a mistake in such matters. Hence they conclude that it is only natural and fitting that a living, speaking, teaching, infallible guide should be appointed by God to direct the Church, and thence they conclude the infallibility of the Pope; a method of argument which has been amply exposed by Dr. Salmon in his work on the Infallibility of the Church. The Roman Catholics form their theory first, and when they come to facts which conflict with their theory, they deny them or explain them away in the most extraordinary manner.
