So now you are an expert on Catholic doctrine? Where did you study the doctrines of the Catholic Church and who were your professors? I am aware of at least 60 references to the works of Paul within the Catechism. Why don't you start with those and explain how they each are outside the Catholic doctrines. When you are done we can get into the dogmatic issues.
I will as soon as you study the Bible and tell me where Catholic doctrines can be found. Be a hero. Show us where we went wrong. Here’s a start: Why wasn’t Paul chosen as the 12th Disciple after Judas? It certainly would have made RCC doctrine run a little smoother. Good luck with your searches.
