4 First, so far as property is concerned, the Portuguese Republic severs itself from the Church in such a way that it leaves her nothing at all from which to provide for the decency of the house of God, the maintenance of the clergy and the exercise of the manifold duties of charity and piety. For by the articles of this decree not only is the Church despoiled of all the property, whether real or movable, which she holds by the strongest of titles, but she is deprived of all power of acquiring anything for the future. It is indeed provided that certain civil bodies shall have the care of exercise of religious worship; but it is astounding to see within what narrow limits permission to receive any offerings for this purpose is circumscribed. Moreover, the obligations under which Catholic citizens have been accustomed to assist or maintain their respective parish priests, these the decree abolishes and suppresses, forbidding anything to be henceforth demanded for this purpose. It allows Catholics to provide for the cost of divine worship by voluntary alms, but it requires that a third of the sum so contributed shall be set apart and employed for works of civil assistance. And to crown all, under this new law, the buildings which may be henceforth acquired or erected for the exercise of religion are, after the lapse of a given term of years, to pass from the rightful owners without any compensation and to become public property.
