At Paris, too, he made the acquaintance of the Catholic Archbishop, Cardinal Noailles. It is marvellous how broad in his views the young man was. As he discussed the nature of true religion with the Cardinal, who tried in vain to win him for the Church of Rome, he came to the conclusion that the true Church of Jesus Christ consisted of many sects and many forms of belief. He held that the Church was still an invisible body; he held that it transcended the bounds of all denominations; he had found good Christians among Protestants and Catholics alike; and he believed, with all his heart and soul, that God had called him to the holy task of enlisting the faithful in all the sects in one grand Christian army, and thus realizing, in visible form, the promise of Christ that all His disciples should be one. He was no bigoted Lutheran. For him the cloak of creed or sect was only of minor moment. He desired to break down all sectarian barriers. He desired to draw men from all the churches into one grand fellowship with Christ. He saw, and lamented, the bigotry of all the sects. "We Protestants," he said, "are very fond of the word liberty; but in practice we often try to throttle the conscience." He was asked if he thought a Catholic could be saved. "Yes," he replied, "and the man who doubts that, cannot have looked far beyond his own small cottage." "What, then," asked the Duchess of Luynes, "is the real difference between a Lutheran and a Catholic?" "It is," he replied, "the false idea that the Bible is so hard to understand that only the Church can explain it." He had, in a word, discovered his vocation.
