I’ve read Scripture. Now what? Do I have to accept your infallible interpretation of Scripture? And if it’s not infallible, why should I care?
In 1 Corinthians 12, Paul tells the Corinthians in the Corinthian church that they are the body of Chirst and individually members of it.
Now, that was the Corinthian church, not the church at Rome.
So that raises two problems for Catholics....
One is that it defines what the true church is.
And two.....
It ain’t Rome.....
