By this thesis, in short, the coming of St. Francis was like the birth of a child in a dark house, lifting its doom; a child that grows up unconscious of the tragedy and triumphs over it by his innocence. In him it is necessarily not only innocence but ignorance. It is the essence of the story that _he_ should pluck at the green grass without knowing it grows over a murdered man or climb the apple-tree without knowing it was the gibbet of a suicide. It was such an amnesty and reconciliation that the freshness of the Franciscan spirit brought to all the world. But it does not follow that it ought to impose its ignorance on all the world. And I think it would have tried to impose it on all the world. For some Franciscans it would have seemed right that Franciscan poetry should expel Benedictine prose. For the symbolic child it was quite rational. It was right enough that for such a child the world should be a large new nursery with blank white-washed walls, on which he could draw his own pictures in chalk in the childish fashion, crude in outline and gay in colour; the beginnings of all our art. It was right enough that to him such a nursery should seem the most magnificent mansion of the imagination of man. But in the Church of God are many mansions. Every heresy has been an effort to narrow the Church. If the Franciscan movement had turned into a new religion, it would after all have been a narrow religion. In so far as it did turn here and there into a heresy, it was a narrow heresy. It did what heresy always does; it set the mood against the mind. The mood was indeed originally the good and glorious mood of the great St. Francis, but it was not the whole mind of God or even of man. And it is a fact that the mood itself degenerated, as the mood turned into a monomania. A sect that came to be called the Fraticelli declared themselves the true sons of St. Francis and broke away from the compromises of Rome in favour of what they would have called the complete programme of Assisi. In a very little while these loose Franciscans began to look as ferocious as Flagellants. They launched new and violent vetoes; they denounced marriage; that is, they denounced mankind. In the name of the most human of saints they declared war upon humanity. They did not perish particularly through being persecuted; many of them were eventually persuaded; and the unpersuadable rump of them that remained remained without producing anything in the least calculated to remind anybody of the real St. Francis. What was the matter with these people was that they were mystics; mystics and nothing else but mystics; mystics and not Catholics; mystics and not Christians; mystics and not men. They rotted away because, in the most exact sense, they would not listen to reason. And St. Francis, however wild and romantic his gyrations might appear to many, always hung on to reason by one invisible and indestructible hair.
