Your interpretations of those scriptures, especially the one about the Church, just isn't right, annalex. The CHURCH is not a denomination or a building. It is the body of believers. WE are His church, annalex. There IS one true church and it's those of us who believe in Jesus Christ as Lord and Savior and live according to His precepts. No Pope is infallible, no church is infallible. Sorry. You are just plain wrong about that.
I guess I could have taken a page from the Protestant book and declare that the Holy Spirit taught me my interpretation. Yes, the Church is a communion of people, -- the people who are baptized and obey the Church. That Church is declared infallible by Christ in Matthew 16 and Matthew 18. It is a very plain text, too, -- no particular exegetical effort is needed.
