In order to understand these words we must bear in mind two important things: that Simon had been given the name Peter by Christ, and that two words are used in this verse – ‘Peter’ and ‘rock’ – which are related but different. When Christ says ‘on this rock I will build my church’, what is he referring to? Once we understand that the name Peter means a stone (John 1:42) – John uses the Aramaic name ‘Cephas’ which is equivalent to the Greek name ‘Peter’ – we might be inclined to think that Christ is saying he will build his church on Peter as an individual.
Firstly, death will never destroy the witness of the church. They could martyr all the preachers, but it did not work. And other way round also – Satan keeps his people enclosed in his fortress, but he can’t keep out the gospel. This message plucks men and women out of his stronghold. Secondly, Christ has warned us we will always be children of the little flock. Although we are a vast number, and heaven will be filled, the fact is that on earth we will never be a majority. Many are called but few chosen. There will be a periodicity about this: times of ascendance, and times of decline, nevertheless over time Christ will have the pre-eminence. Now we are in an age when godlessness seems to triumph. The fact that the church is called out of a hostile environment is its glory. The church of Christ will never be eliminated till the end. Generations of Christians, particularly churches may lose their candlestick, but when you take all into account, there will always be a flame.
You might think that the matter of who runs the church is not a big issue, but it is. Mistakes always have a beginning and the idea of a pope has led to many other errors. There is not a word about this in the passage but the Roman Catholic church teaches that the authority given to Peter was passed on to his successors. If this only involved Peter, we might not be so anxious, for he never committed all these errors, but to say that the headship of the church is given to Peter is a root of error. By teaching this the Roman Catholic church creates an additional authority alongside the Bible. Successive popes have added to the Bible. They have added new teaching practices, and claimed Christ’s authority for doing so; it is a matter of adding a second Bible. What is our authority? The Bible alone.
What does the rest of the New Testament say about Peter? Peter as an individual was weak at times. The New Testament gives him a surprisingly small role, Paul writing far more of the New Testament, and Peter playing a very important but nonetheless smaller part in the great commission. After Acts 15 – about halfway through the book – Peter isn’t mentioned again; he disappears from the record, not because he is disapproved of, but because the focus moves to Paul and the spreads of the gospel to the Gentiles. In the letter to the Galatians, Peter’s serious fall is recorded and he had to be corrected by Paul. He failed to act consistently with the truth of the gospel. In the New Testament Peter is never seen as a teacher or pastor in Rome. Yes he may have gone there, and even died there, but if the whole church is to be under the pope, the Bishop of Rome, then it is extraordinary not to mention his ministry there. Paul says that he longed to visit Rome. Why? Because they have no apostolic person there, and so Paul will impart some spiritual gift to them. Peter is called ‘one’ of the pillars of the church (Galatians 2:9), but James is named before him and it is James who puts forward the argument. This does not support the idea that Peter was the head of the church on earth. Nowhere else in the New Testament is there the slightest hint that the church is built on Peter. Certainly, a verse in Ephesians called the apostles the foundation, but that is a rare use of the term which refers to the apostles’ role as channels of New Testament revelation. Far more often however the Scripture speaks of Christ as the foundation, and Paul says there is really no other foundation (1 Corinthians 3:11). Peter did truly have a privilege. He answered for all, and perhaps he got his reward for being the first to make this confession. He was not the pope, but he was the first to say this, and he took the leading role in preaching to the Jews at Pentecost, and to Cornelius as the gospel advanced to the Gentiles.
