Apostle Paul's Lost Letters

(Some) scholars assume that Paul wrote four letter to the church in Corinth. Apparently, two of these letters were lost. My Biblical Literature class discussed what the church should do if archaeologists uncovered authentic copies of these two letters.

The class consensus was that these letters should not be placed in the canon. I disagree. Below are two reasons why I think these two letters should be canonized.

1. One factor in canonization was the apostolic authorship. If the letters were written by the apostle Paul, they are no less authoritative because they were discovered later.

2. We can only benefit from Paul's letters. He was the great prophetic voice for the first church and all of history after that. His teachings are worthy of canonization

There is a negative issue: our church organization is vastly different then it was during the first canonization time period. The church was unified enough to have an authoritative voice that represented Christianity. One qualification for canonization was that each book was accepted by the whole church leadership. Currently, we have no unified leadership, except for the organization within the Catholic church.

I have recently gained a new interest in the canonical process. What are my audiences thoughts? If we found the two letters addressed to Corinth and we could verify they were authentic letters written by Paul, should we add them to our Bible?
