Unlike you, I don’t subscribe to Sola Scriptura, so I don’t have the same logical problem.
So I reiterate: you claim Sola Scriptura, as do Lutherans, Baptists, Evangelicals, Calvinists, and Fundamentalists, among other Protestant denominations. Yet we have mutually exclusive theological positions that emerge, as I have already pointed out.
Who decides who is right? How do you determine which one is true?
