Let's say I hold it on faith that what you believe is wrong. That there are no angels there. That the Christian God does not exist. Let's say I apply your epistemology and hold that on faith.
Then I would assume you are a scientist.
(Am I right, by the way?)
How could you demonstrate that one or the other of these claims is true or false?
Well, for starters, I could show you statuary, paintings, churches, hospitals, organizations, symbols on flags & banners, billboards, demonstrations, legislation, bits of Scripture on buildings, and historical documents that demonstrate there's more to reality than meets the eye.
When you see these things, what do you see?
Beautiful art or more than meets the eye (or both)?
They cannot both be right, and any good epistemology offers us a way to determine between true and false claims. There is nothing to differentiate your faith from the faith of a Muslim.
I beg to differ.
You just said "any good epistemology offers us a way to determine between true and false claims."
Our "good epistemology" does just that.
You see, we claim there were no more prophets since the completion of the Scriptures in AD 96.
Anyone, such as Mohammad or Joseph Smith, claiming they are prophets automatically incurs our denial.
Why aren't you a Muslim instead of a Christian?
Because I believe Mohammad was a false prophet.
Many Christians in his day accused him of just that and paid for it with their lives.
We call those people "martyrs" -- but many here prefer to call them "believers in something they knew was wrong."
