I. After [16]the Lord's ascension a most important point immediately arose, whether, that is, the number of the Twelve was to be filled up by the election of a new Apostle to take the place of Judas. The will of Christ on this matter was to be learnt; a witness was to be chosen who should participate in the mission of Christ Himself, according to the words, "As the Father hath sent Me, I also send you," and carry the light of the Gospel to the ends of the world; and one was to be elected to the dignity of the Apostolate, the highest rank in the Church. It was, therefore, so important a matter, that no one could undertake it save he who had received the vicarious headship of our Lord Himself. Now the history in the Acts tells us that Peter alone spoke on the subject of substituting a fresh Apostle for Judas; Peter alone proved from Scripture the necessity of the election, defined the conditions of eligibility, and appointed the mode of election, and presided over and directed the whole transaction.

For Luke begins thus: "In those days," the interval between the Ascension and Pentecost, "Peter rising up in the midst of the brethren, said." Here the important prerogative of initiation is shown to belong to Peter, and by the phrase, "in the midst of the brethren," or "disciples,"—which is often used of Christ in respect of the Apostles—his pre-eminence over the disciples is shown. "Brethren, it behoved that the Scripture should be fulfilled which the Holy Ghost spoke before by the mouth of David, concerning Judas, who was the leader of them that apprehended Jesus, who was numbered with us, and had obtained part of this ministry," that is, of the Apostolate. Then having mentioned the miserable end of the traitor, he applies to him the prophecy: "For it is written in the Book of Psalms, 'Let his habitation become desolate, and let there be none to dwell therein:' and, adding another prophecy from another Psalm, 'his bishopric let another take.'"[17] Whence he concludes, "Wherefore of these men who have companied with us all the time that the Lord Jesus came in and went out among us, beginning from the baptism of John, until the day wherein He was taken up from us, one of these must be made a witness with us of His resurrection." In these words Peter plainly points out the necessity of the matter in question, confirms it by the Holy Scriptures, speaking in the character of their highest interpreter, and as the appointed teacher of all; and, while proposing it to their deliberation, yet requires their consent; for the phrase, "wherefore, one must," means, "I am not proposing what may be done or left undone, but declaring and prescribing what is to be done." So he determines the conditions of eligibility, and the form of election. Whereupon his hearers—"the number of persons together about an hundred and twenty"—instantly agree unanimously to Peter's proposition, follow its conditions, and complete the election.

No one can reflect on the above without concluding, that if Peter presided over the rest by the authority of a divinely chosen headship, no course could be more becoming, both for Peter and for the disciples, than this; and if, on the contrary, Peter was only one out of many, not having yet even received the Pentecostal gifts of the Holy Spirit, and had been entrusted by Christ with no pre-eminent office in the ministry, nothing could be more unfitting for both. We have therefore to infer that Peter "stood in the midst of the disciples," as a superior among inferiors, not as an equal among equals, and conceived that the charge of supplying an Apostle, and filling up the Apostolic college, belonged in chief to himself, because he and they alike were conscious, that he was the steward set in chief over the Lord's family.

But, clear as this is on the face of the narration itself, fresh light is shed on it by the fact that S. Chrysostome observed and recorded this very conclusion. For why did Peter alone arise? Why was he the first and the only one to speak? "Both[18] as fervent, and as one entrusted by Christ with the flock, and as the first of the choir, he ever first begins to speak." Why does he allege prophecy? First, that he might not seem with human counsel "to attempt a great matter, and one fitted for Christ:" next to imitate his Master, "he always reasons from the Scriptures." "Why did he not singly ask of Christ to give him some one in the place of Judas?" Because "Peter had now improved," and overcome his natural disposition. But "might not Peter by himself have elected? Certainly: but he does not so, that he may not seem partial." "Why does he communicate this to them," the whole number of the names? "That the matter may not be contested, nor they fall into strife: for" (he alludes to the contention of the Apostles for the primacy,) "if this had happened to themselves, much more would it to the others," that is, the candidates to succeed Judas. Then he points out to our admiration "Peter doing this with common consent, nothing[19] with authority, nothing with lordship," where we must note that the abuse of a power is only to be feared from one who really has that power. For again he says, "he first acts with[20] authority in the matter, as having himself all put into his hands, for to him Christ said, 'And thou in thy turn one day confirm thy brethren.'"

The college of the Apostles completed, it followed that the head, if such there were, would on every occasion of danger, be the first to protect it, and to defend its reputation. Now there ensues the miracle of the Holy Spirit's descent, and the gift of tongues, whereupon Luke describes the various opinions of the astonished multitude, some of whom "mocking,[21] said, These men are full of new wine." That is, they blasphemed the working of the Spirit, and by the most monstrous calumny were destroying the good name of the Apostles. Whereupon, "Peter, standing up with the Eleven, lifted up his voice and spoke to them: Ye men of Judea, and all you that dwell in Jerusalem, be this known to you, and with your ears receive my words. For these are not drunk as you suppose, seeing it is but the third hour of the day: but this is that which was spoken of by the prophet Joel." Now here, both the form of the words, and the matter, establish Peter's primacy. For the phrase, "Peter standing up with the Eleven, lifted up his voice and spoke to them," portrays Peter as the leader of the band, the master of the family. So S. Chrysostome,[22] "What means with the Eleven? They uttered a common voice, and he was the mouthpiece of all. And the Eleven stand beside him, bearing witness to his words." And as to the matter, Peter alone fulfils the part of teacher, by interpreting scripture, and declaring the agreement of both covenants: Peter alone maintains the common cause: Peter alone, representing all, addresses the multitude in the name of all. "Observe, too, the harmony of the Apostles: they give up to him the office of speaking:"[23] that is, they yielded to him who was the Head, and who, as he says, showed here "the courage," as before "the providential care" of the Head.

After refuting the calumny, Peter goes on in a noble discourse to explain prophecies, and then coming to the dispensation of Jesus, gives the strongest proofs of His resurrection and exaltation to the right hand of the Father, and finally sums up with great force and authority. "Therefore, let all the house of Israel know most certainly, that God hath made both Lord and Christ this same Jesus whom you have crucified."

Now, what[24] is here to our purpose? It is this, that Luke seems only to dwell on what concerns Peter: that Peter, first of all, and in the name of all, performs the office of a witness, laid both on himself and the rest, ("ye shall be witnesses to Me;" "and you shall give witness,")[25] saying, "this Jesus hath God raised up, of which we all are witnesses:" that first of all, he publicly and solemnly discharges the duty of instruction with authority: that, first of all, he fulfils the charge set by Christ on all the Apostles, "make disciples—teach:" that, first of all, he promulgates the necessity of believing in Jesus as the divinely appointed Lord and Christ. Now these are things which, so far from allowing an equality between Peter and the rest of the Apostles, point out in him a headship over them.

Thereupon, the hearers, struck with compunction for having crucified, not merely a just man, but the Anointed of the Lord, "said to Peter and the rest of the Apostles"—here again he alone is singly named—but of all alike they asked, "Men and brethren, what shall we do?" Whereupon, S. Chrysostome[26] notes, "here again, where all are asked, he alone replies." For, as Luke goes on, "Peter said to them:" As the leader, he performs what belongs to all: he alone sets forth the law of Christ. "Do penance, and be baptized every one of you, in the name of Jesus Christ, for the remission of sins:" he alone encourages them with the promised gifts of the Holy Spirit, "and you shall receive the gift of the Holy Ghost:" he alone continues at length the instruction of the hearers, "and with very many other words did he testify and exhort them:" he alone declares the fruit of Christian profession, "save yourselves from this perverse generation," and he alone it is, of whose ministry Luke adds, "They, therefore, that gladly received his word were baptized, and there were added, in that day, about three thousand souls."

And here we see how fitting it was that Peter, whom Christ had set as the foundation and rock of the Church, should labour with all his might, as the chief architect after Him, to build up the structure. But what, in the meantime, of the other Apostles? Were not they also architects? Yes, but with Peter, and under Peter, whom accordingly, they attend and support. The subsequent additions to the Church's structure, and the course consistently pursued by Peter, will bring this out yet more clearly. For, of fresh accretions, Luke writes, "Many of them who had heard the word, believed, and the number of the men was made five thousand."[27] Now, whose word was this? Still the word of Peter, who speaks for the third[28] and fourth time, as he had for the first and second.

For, as to the third[29] occasion, Luke, after mentioning Peter and John together, introduces Peter alone as urging the children of Abraham to embrace the faith of Christ, and persuading them that Jesus is the Prophet, promised by God through Moses in Deuteronomy. And as to the fourth,[30] he writes, "Then Peter, filled with the Holy Ghost, said to them—" But was he alone present? not so, for the council "setting them," not him, but John as well as Peter, "in the midst, they asked," on which Chrysostome[31] observes, "See how John is on every occasion silent, while Peter defends him likewise." That is, John was silent, as knowing that the lead belonged to Peter, and Peter spoke, because the Head defends not himself only, but the members committed to him.
