By certain indications it is not difficult to conclude that among Catholics – doubtless as a result of current evils – there are some who, far from satisfied with the condition of “subject” which is theirs in the Church, think themselves able to take some part in her government, or at least, think they are allowed to examine and judge after their own fashion the acts of authority. A misplaced opinion, certainly. If it were to prevail, it would do very grave harm to the Church of God, in which, by the manifest will of her Divine Founder, there are to be distinguished in the most absolute fashion two parties: the teaching and the taught, the Shepherd and the flock, among whom there is one who is the head and the Supreme Shepherd of all.
To the shepherds alone was given all power to teach, to judge, to direct; on the faithful was imposed the duty of following their teaching, of submitting with docility to their judgment, and of allowing themselves to be governed, corrected, and guided by them in the way of salvation. Thus, it is an absolute necessity for the simple faithful to submit in mind and heart to their own pastors, and for the latter to submit with them to the Head and Supreme Pastor. In this subordination and dependence lie the order and life of the Church; in it is to be found the indispensable condition of well-being and good government. On the contrary, if it should happen that those who have no right to do so should attribute authority to themselves, if they presume to become judges and teachers, if inferiors in the government of the universal Church attempt or try to exert an influence different from that of the supreme authority, there follows a reversal of the true order, many minds are thrown into confusion, and souls leave the right path.
And to fail in this most holy duty it is not necessary to perform an action in open opposition whether to the Bishops or to the Head of the Church; it is enough for this opposition to be operating indirectly, all the more dangerous because it is the more hidden. Thus, a soul fails in this sacred duty when, at the same time that a jealous zeal for the power and the prerogatives of the Sovereign Pontiff is displayed, the Bishops united to him are not given their due respect, or sufficient account is not taken of their authority, or their actions and intentions are interpreted in a captious manner, without waiting for the judgment of the Apostolic See.
Similarly, it is to give proof of a submission which is far from sincere to set up some kind of opposition between one Pontiff and another. Those who, faced with two differing directives, reject the present one to hold to the past, are not giving proof of obedience to the authority which has the right and duty to guide them; and in some ways they resemble those who, on receiving a condemnation, would wish to appeal to a future council, or to a Pope who is better informed.
On this point what must be remembered is that in the government of the Church, except for the essential duties imposed on all Pontiffs by their apostolic office, each of them can adopt the attitude which he judges best according to times and circumstances. Of this he alone is the judge. It is true that for this he has not only special lights, but still more the knowledge of the needs and conditions of the whole of Christendom, for which, it is fitting, his apostolic care must provide. He has the charge of the universal welfare of the Church, to which is subordinate any particular need, and all others who are subject to this order must second the action of the supreme director and serve the end which he has in view.
