From a sermon by Saint Augustine
|The martyrs had seen what they proclaimed|
This day has been consecrated for us by the martyrdom of the blessed apostles Peter and Paul. It is not some obscure martyrs we are talking about. Their sound has gone out into all the earth, and their words to the ends of the world. These martyrs had seen what they proclaimed, they pursued justice by confessing the truth, by dying for the truth.
The blessed Peter, the first of the Apostles, the ardent lover of Christ, who was found worthy to hear, And I say to you, that you are Peter. He himself, you see, had just said, You are the Christ, the Son of the living God. Christ said to him, And I say to you that you are Peter, and upon this rock I will build my Church. Upon this rock I will build the faith you have just confessed. Upon your words, You are the Christ, the Son of the living God, I will build my Church; because you are Peter. Peter comes from petra, meaning a rock. Peter, “Rocky,” from “rock”; not “rock” from “Rocky.” Peter comes from the word for a rock in exactly the same way as the name Christian comes from Christ.
Before his passion the Lord Jesus, as you know, chose those disciples of his whom he called apostles. Among these it was only Peter who almost everywhere was given the privilege of representing the whole Church. It was in the person of the whole Church, which he alone represented, that he was privileged to hear, To you will I give the keys of the kingdom of heaven. After all, it is not just one man that received these keys, but the Church in its unity. So this is the reason for Peter’s acknowledged pre-eminence, that he stood for the Church’s universality and unity, when he was told, To you I am entrusting, what has in fact been entrusted to all. To show you that it is the Church which has received the keys of the kingdom of heaven, listen to what the Lord says in another place to all his apostles: Receive the Holy Spirit; and immediately afterwards, Whose sins you forgive, they will be forgiven them; whose sins you retain, they will be retained.
Quite rightly, too, did the Lord after his resurrection entrust his sheep to Peter to be fed. It is not, you see, that he alone among the disciples was fit to feed the Lord’s sheep; but when Christ speaks to one man, unity is being commended to us. And he first speaks to Peter, because Peter is the first among the apostles. Do not be sad, Apostle. Answer once, answer again, answer a third time. Let confession conquer three times with love, because self-assurance was conquered three times by fear. What you had bound three times must be loosed three times. Loose through love what you had bound through fear. And for all that, the Lord once, and again, and a third time, entrusted his sheep to Peter.
