The Church decides and sorts out the issue if the issue cannot be resolved between the brothers. Christ affirms that the end authority is in fact the Church.

There is no Church in the bible...There is however a church, and many churches...

The Berean church in the scriptures gave us the example...The churches are supposedly led by faithful Christians who study and search the scriptures by comparing scripture with scripture to 'prove all things' and that is where their authority to settle the matter lies...

“There is no Church in the bible...There is however a church, and many churches”

Ekklesia. Singular. There is one Church and many congregations.

“and that is where their authority to settle the matter lies”

Actually the authority of the Church stems from Christ himself. The bible is a product of the Church not the Church of the bible.
