1) Paul encourages people to remain virgin. Furthermore, not only Peter but a number of Popes and early Christians were married. This does not aid you in negating the Papacy and the fact that Christ elected Peter as the head of the Apostles, not to mention he (Peter) is the rock where Jesus would build his Church.
Side note: I’m repeating myself with regards to the rock comment, something I never clarified.
On another post you say “Christ is the rock in which the Church is built”, and although I don’t disagree with you statement, in Mt 16:18:
“And I tell you that you are Peter (Cephas), and on this rock (Cephas) I will build my church, and the gates of Hades will not overcome it.”
Peter, or Petro in Latin, means rock. But in its original language, Aramaic, the Evangelist used the word Cephas both for Peter’s name and when he described the rock.
2) The Pope is only infallible when pronouncing Doctrine, together with the Bishops. The Pope cannot tell you next week’s lotto numbers. The passage you quote, Peter is not pronouncing Doctrine, he is simply making a human mistake, as all Popes do. Again, this does not refute the Papacy.
3) 1 Corinthians 3:11 says: “For no one can lay any foundation other than the one already laid, which is Jesus Christ”. This verse by itself means nothing if you do not put it in context. This is something Fundamentalists do often.
In this case simply look at the verse right before it (1 Cor 3:10): “By the grace God has given me, I laid a foundation as an expert builder, and someone else is building on it. But each one should be careful how he builds.”
In 1 Cor 3:11 it reads that no one can lay a foundation other than Christ but in the preceding verse, Paul says that he himself, by the Grace of God, has laid foundations. Furthermore, the Pope only lays foundations, which are not really foundations but clarifications of Doctrines that in all cases were held by Catholics since the first Centuries of Christianity, guided by the Holy Spirit, just like Paul is aided by the Grace of God when he lays foundations in 1 Cor 3:10.
I could go on and on refuting one by one your points, but this post would end up being to long.
