The Qur'an contradricts the bible so it can't be true.
Flip that around. What if I said the Bible contradicts the Qur'an so, therefore, the Bible cannot be true.
Would you accept that?
You're holding up the Bible as the absolute standard or truth, yet the only way you can justify that is to simply assert that the Bible is true because it says so.
When I pointed out that the Qur'an claimed to be true too, you immediately dismissed it.
You're using an obvious double standard.
The Qur'an claims everything the Bible does. It claims to be true and it claims to be divinely inspired.
If the Qur'an is wrong in making those claims, how do you know the Bible is right?
I don't see how it's flawed.
Because your asserting that the Bible is true and then, when asked how you know that, answering with either "because it's true" or "because it says so".
"The Bible is true because it says so."
"The Bible is true."
(Assertion 1)
How do you know?
(Assertion 1 is questioned)
"Because it' says so."
- This is meaningless. Until your initial premise "The Bible is true" can be validated, it makes no sense to appeal to the Bible itself because the next question will always be "And how do you know the Bible is accurate?"
"The Bible is true because it's true."
"The Bible is true."
(Assertion 1)
How do you know?
(Assertion 1 is questioned)
"Because it's true."
(Assertion 1 is defended with assertion 1)
"The Bible is true because it's God's word" - I covered this one earlier
"The Bible is the word of God."
(Assertion 1)
How do you know? (Assertion 1 is questioned)
"Because the Bible says so."
(Assertion 1 is defended with assertion 2)
How do you know the Bible is accurate? (Assertion 2 is questioned)
"Because the Bible is the word of God."
(Assertion 2 is defended with assertion 1)
The three arguments above are all circular.
