16 Do you then, Venerable Brethren, awaken the sleeping, stimulate the hesitating; by your example and your authority train them all to fulfil with constancy and courage the duties which are the Christian life in action. And in order to maintain and develop this revived courage, means must be taken to promote the growth, multiplication, harmony, and fruitfulness of Associations the principal object of which should be to preserve and excite zeal for the Christian faith and other virtues. Such are the associations of young men and of workmen; such are the committees organized by Catholics, and meeting periodically; such are the institutions destined to relieve poverty, to protect the sanctification of festival days, to instruct the children of the poor, and several others of the same kind. And since it is of supreme importance to Christian interests that the Roman Pontiff should be, and should be clearly seen to be, free from all danger, from all vexations, and from all hindrance in the government of the Church, it is necessary, to attain this end, that action should be taken, petitions, and every possible means within the limits of the law should be adopted, and that none should rest until We have restored to Us, in reality and not in appearance only, that liberty on which, not only the welfare of the Church, but the prosperity of Italy and the peace of Christian nations depend by a necessary connection.
