It was no part of Francis's design that the friars should live by idle mendicancy, and we have seen that the Rule expresses the obligation to labor. This was obeyed by the stricter members. Thus his third disciple, the blessed Giles, earned his subsistence by the rudest work, such as that of carrying wood, and he always adhered to the precept not to take wages in money, but in necessaries for his support. When he had earned more than enough for the scanty subsistence of the day, he would give away the surplus in charity, and trust to God for the morrow. It was well that, in an age of class distinctions so rigid, there should be some to teach practically the dignity of labor as a Christian doctrine. When St. Bonaventura was elevated to the cardinalate, in 1273, he had for seventeen years been the head of what by that time was the most powerful organization in Christendom, yet the messengers sent to announce to him his promotion arrived while he was engaged in his daily task of washing the dishes used in the frugal dinner of his convent. He refused to see them till his work was finished, and meanwhile the hat which they had brought was hung upon the branch of a tree.[236] Thus the aim of St. Francis and his followers was to realize the simplicity of Christ and the apostles, and in nothing was this manifested with so much fervor as in their seeking after poverty. They argued that Jesus and his disciples owned nothing, and that the perfect Christian must likewise divest himself of all property. Of food and clothing and shelter he might have the use, as likewise of books requisite for his religious needs, but property of all kinds was absolutely prohibited, and the Christian's trust in God rendered forethought for the morrow a sin. As a protest against the avarice and worldliness of the Church, this was of exceeding value, but it was pushed to an extravagance which idealized poverty as an intrinsic good, and the greatest of all goods. "Brethren," said St. Francis, "know that poverty is the special path to salvation, the inciter to humility, and the root of perfection.... He who seeks to attain the height of poverty must, in a sense, renounce not only worldly prudence, but the knowledge of letters, so that, divesting himself of these possessions, he may offer himself naked to the arms of the Crucified.... Wherefore, like beggars, build little hovels in which to live, not as in your own, but as strangers and pilgrims in the houses of others." His prayer to Christ for poverty is a curiously earnest rhapsody. She is Lady Poverty, the Queen of virtues, for whose sake Christ descended unto earth, to marry her and beget on her all the children of perfection. She clung to him with inseparable fidelity, and in her arms he died upon the cross. She alone possesses the seal with which to mark the elect who choose the way of perfection. "Grant me, O Jesus, that I may never possess under heaven anything of my own, and sustain the flesh sparely by the use of the
