I've not verified (lately) but I believe most of Paul's letters to the church were written while he was captive in Rome.
Paul's Prison Epistles show that after Israel is set aside, (Acts 28), he writes through inspiration of the Holy Spirit, Ephesians, Colossians, Philippians, Philemon, 1 Timothy, 2 Timothy, Titus. In that order.
A very interesting study of his writings, on their timeline and content; pre-prison, and prison could be greatly used here and would go a long way to the Church the Body of Christ understanding the transition from the Jewish Age to the Church Age, that Acts so beautifully points out.
Jesus “Acts 23:11 11 The following night the Lord stood by him (Paul) and said, “Take courage, for as you have testified to the facts about me in Jerusalem, so you must testify also in Rome.”
The assertion made by the poster is just another example of the lack of understanding of what scripture actually teaches. I think that most followers of the RCC simply put the RCC above scripture, Christ or anything else scripture teaches whether they realize it or not.
Actually, the only ones that may have been written in Rome were Timothy and Titus. All the rest (including Romans), were written well before.
Romans is believed to have been written either in Corinth or Antioch.
