In view of the purposes with which, and with which alone, these early popes employed their supreme power, the contention, so stoutly maintained by Protestant controversialists, that the Roman primacy had its origin in papal ambition, disappears. The motive which inspired these men was not earthly ambition, but zeal for the Faith and the consciousness that to them had been committed the responsibility of its guardianship.
The controversialists in question even claim that they are justified in refusing to admit as evidence for the papal primacy any pronouncement emanating from a Roman source, on the ground that, where the personal interests of anyone are concerned, his statements should not be admitted as evidence. Such an objection is utterly fallacious. We are dealing here, not with the statements of an individual, but with the tradition of a Church â of that Church which, even from the earliest times, was known for the purity of its doctrine, and which had had for its founders and instructors the two chief Apostles, St. Peter and St. Paul. That tradition, moreover, is absolutely unbroken, as the pronouncements of the long series of popes bear witness.
Nor does it stand alone. The utterances, in which the popes assert their claims to the obedience of all Christian Churches, form part and parcel of a great body of testimony to the Petrine privileges, issuing not merely from the Western Fathers but from those of Greece, Syria, and Egypt. The claim to reject the evidence which comes to us from Rome may be skilful as a piece of special pleading, but it can claim no other value. The first to employ this argument were some of the Gallicans. But it is deservedly repudiated as fallacious and unworthy by Bossuet in his âDefensio cleri gallicaniâ (II, 1. XI, c. vi).
**The primacy of St. Peter and the perpetuity of that primacy in the Roman See are dogmatically defined in the canons attached to the first two chapters of the Constitution âPastor Aeternusâ: **
**âIf anyone shall say that Blessed Peter the Apostle was not constituted by Christ our Lord as chief of all the Apostles and the visible head of the whole Church militant: or that he did not receive directly and immediately from the same Lord Jesus Christ a primacy of true and proper jurisdiction, but one of honour only: let him be anathema.â **âIf any one shall say that it is not by the institution of Christ our Lord Himself or by divinely established right that Blessed Peter has perpetual successors in his primacy over the universal Church, or that the Roman Pontiff is not the successor of Blessed Peter in this same primacy. â let him be anathemaâ (Denzinger-Bannwart, âEnchiridionâ, nn. 1823, 1825).
A question may be raised as to the precise dogmatic value of the clause of the second canon in which it is asserted that the Roman pontiff is Peterâs successor. The truth is infallibly defined. But the Church has authority to define not merely those truths which form part of the original deposit of revelation, but also such as are necessarily connected with this deposit. The former are held fide divina, the latter fide infallibili.
Although Christ established the perpetual office of supreme head, Scripture does not tell us that He fixed the law according to which the headship should descend. Granting that He left this to Peter to determine, it is plain that the Apostle need not have attached the primacy to his own see: he might have attached it to another.
Some have thought that the law establishing the succession in the Roman episcopate became known to the Apostolic Church as an historic fact. In this case the dogma that the Roman pontiff is at all times the Churchâs chief pastor would be the conclusion from two premises â the revealed truth that the Church must ever have a supreme head, and the historic fact that St. Peter attached that office to the Roman See. This conclusion, while necessarily connected with revelation, is not part of revelation, and is accepted fide infallibili.
According to other theologians the proposition in question is part of the deposit of faith itself. In this case the Apostles must have known the law determining the succession to the Bishop of Rome, not merely on human testimony, but also by Divine revelation, and they must have taught it as a revealed truth to their disciples. It is this view which is commonly adopted. The definition of the Vatican to the effect that the successor of St. Peter is ever to be found in the Roman pontiff is almost universally held to be a truth revealed by the Holy Spirit to the Apostles, and by them transmitted to the Church.
