"That would be because that verse is totally misinterpreted by the CC and contradicts the rest of scripture."
Even Irenaeus never uses this argument or any other argument for a divinely given special status for the Church of Rome. And the most straightforward explanation is that he never heard of such a doctrine.

Peter is the Rock -vs- Jesus is the Rock > Perhaps there is another more obvious answer that ...(we) are missing. We need only look at the preceding verses to find it:
15 Jesus saith to them: But whom do you say that I am? 16 Simon Peter answered and said: Thou art Christ, the Son of the living God. 17 And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven. 18 And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it. (Matthew 16:15-18 Douay- Rheims)When Jesus talks about "this rock" he is not referring to Peter, but instead Peter's confession of faith in the preceding verses. Jesus isn't jumping from one subject (that He is the Christ) to another (primacy of Peter). It is a continuation of the same subject - who do people believe that Christ is. If you look at the following verse 20 you can see that Jesus has not changed subject because he is commanding them not to reveal that He is the Christ. > Jesus thus does not declare the primacy of Peter, but rather declares that his church will be built upon the foundation of the revelation of and confession of faith of Jesus as the Christ. The "rock" gentlemen is our faith in Christ. (posted by Between the Lines) ... [That was so well stated that I would only add, 'faith' is an action word, as in 'to faithe' in the delivering Power and Grace of God through Jesus Christ in the person of the Holy Spirit indwelling the faither.]

One method of Hermeneutical understanding of Matthew 16:18 is to do a word study of all the scriptures which were then known as the Holy Word of G-d when Y'shua spoke these words. This will allow one to understand that all of the Holy Word of G-d was inspired by YHvH; the whole counsel of G-d.
The only conclusion that one can come to unless you are predisposed to believe in man's tradition over the Holy Word of G-d is that Y'shua was speaking of himself as the "Rock " e.g.
