55 The spirit of poverty is a special mark of Christ's Gospel. This passing reference to its necessity and excellence does not, however, relieve Us of Our obligation of pointing out that zeal for poverty is no obstacle to the proper understanding and rightful application of the important laws of economics. This is a subject which has made great strides within recent years. It has been responsible for the progress of civilization, especially in its human and social aspects. But We consider that the inner freedom which results from zeal for evangelical poverty makes us in fact more sensitive to the human aspects of economic questions, and better fitted to understand them. We can pass, where necessary, a calm and often severe judgment on wealth and on the luxuries of life. We can come promptly and generously to the aid of those in need, and do our utmost to ensure that wealth, far from being a source of conflict, selfishness and pride amongst men, shall be used justly and equitably for the good of all, and distributed with greater foresight. In all that concerns these external goods-goods which are indeed inferior to those that are spiritual and eternal, but which are nevertheless necessary in this present life-the student of the Gospel can come to a prudent decision. He has a real, human contribution to make in this field. We are most keenly interested in science, technology, and especially in work. The bread which they produce is sacred, whether destined for the table or the altar. This is the Church's traditional social teaching, and it leaves no room for doubt. It is a salutary doctrine. We readily seize this opportunity of confirming it by Our own authority.
