Michael,
I’m not a member of the magesterium. Even if I were it would make no difference whatsoever. You discount the quotes and connections I made in my post. I think you are mistaken. The OT verses are not a prophecy and I never claimed they were.
You claim rather weakly that the verses I presented are a form of eisegesis. I think you would be very hard pressed exegetically to refute the use of those scriptures and their relationship to one another. You make the false assumption that Matthew should have somehow made a statement about the fulfillment of the OT passages relative to the papacy as if this was the fulfillment of a prophecy. This is nonsense and you have no basis for your suggestion. No one claims that this is a prophecy. Instead, you should be seeing the OT connections and the consistency of the Divine plan throughout salvation history. Moreover, the language Jesus used in Matthew 16:18-19 would have been obvious to his disciples and any other Jewish listeners.
You need to understand that scripture is a high context set of documents and within the context of Jewish culture and the Christian Church you will recieve a better understanding of what it means. The disciples would have immediately connected Jesus words to the OT even though you do not. Also consider the fact that God never left the Jews with just the Torah. He sent Moses and the prophets. They always had leadership. Even though Christ rips the Jewish leaders for their hypocrisy, Jesus still tells the people in Matthew 23:1-3, " THEN SAID Jesus to the crowds and to his disciples, “The scribes and the Pharisees sit on Moses’ seat; so practice and observe whatever they tell you, but not what they do; for they preach, but do not practice.” The Jews had a form of magesterium just as we do.
You must understand and appreciate the fact that the Father loves His children and He does not want them being “tossed to and fro and carried about with every wind of doctrine.” You claim that evangelicals agree on 95% of doctrine. I would like you to provide at least an approximate proof of that statement. My evangelical friends disagree on many of what I consider to be important teachings. I find them disagreeing on baptism, once saved always saved, the end times, repentance, and the meaning of grace. In fact Louis Harris, an evangelical himself, has routinely polled non-catholic Christians on the subject of grace and has concluded over and over again that most do not know or understand what “grace” is.
Non-catholic Christians disagree on many things. Moreover, what is disagreed on may be even more important than the actual number of things upon which they disagree . These divisions among Christians are extremely important. Carefully and prayerfully read the 17th Chapter of John. If there is a scandal and woeful disorder within Christianity it is our lack of unity. If you disregard the Catholic Church and just look at the believers that are left and examine the disunity therein you will begin to appreciate the problem. All of the divisions outside of the Catholic Church claim the same thing when it comes to their authority. They all agree that it is the bible alone, but they all have serious disagreements over what the bible says. These disagreements are serious and they fly in the face of the unity prayed for by Jesus.
