The Bible speaks the Truth therefore God exists?

[James R]

(p1) A and (A implies B), therefore B;

(p2) B and (B implies A), therefore A;
(C) Therefore, A and B.​

Question 1: Do you think that this argument is logically valid, and why?​

​

Sure, it's logically valid. It reduces to:

P1. A.
P2. B.
C. A and B.

Question 2: Do you think that this argument is fallacious, and if so, what kind of fallacy is it?

Depends what you mean by fallacious. It's garbage in, garbage out. The conclusion is only as good as the premises.

Refer to my more-concise version, above. If A or B is false, the conclusion immediately collapses in a heap. It's not the logic that is at fault, it's the assumption that P1 and P2 are truths in the first place.

OK, good.

But then that makes the argument unsound, not fallacious.
GIGO applies equally to all valid arguments.
A fallacy is an argument where the reasoning is somehow flawed.
It is usually accepted that valid arguments can be fallacious.
Your comment suggests you don't see this one as fallacious, only unsound.

A fallacy is an argument where the reasoning is somehow flawed.

In order for reasoning to be flawed - or sound - there would have to be reasoning.
What you've got there is three consecutive iterations of the same unfounded pair of factors connected by an unsupported "therefore". These are not premises and conclusion.
What's dressed up as an argument is merely three rearranged versions of the same statement.
This would be so, even if the content were gold, not garbage.

p1. Gold (and Gold implies garbage) therefore garbage
p2. garbage (and garbage implies gold) therefore gold
C: therefore Gold and garbage

But then that makes the argument unsound, not fallacious.

As I said, that's just a matter of which terminology you prefer to use. If you prefer to use "unsound" to refer to informal fallacies, I don't have a problem with that.

Again, we could, were we so inclined, quibble over words and definitions. I'm not particularly fussed, either way.

You might say that the "reasoning" is only what is in the formal logical argument as set out, from which it follows that if the premises are garbage then the argument is merely unsound, as opposed to fallacious. On the other hand, you might say that the soundness of the premises is part of the "reasoning", in which case the unsoundness is a "fallacy", albeit of an informal kind.

Donald Trump is French;
All French people speak French;
Therefore, Donald Trump speaks French.​

This is valid but unsound. I don't think anyone would claim it is fallacious or that the reasoning is flawed. The premises are merely false.
The same form of argument could be applied to Macron instead of Trump, so you don't want to say that a sound argument is the same as a fallacious argument but with true premises.

I don't have anything to add to my last post. No need to repeat myself.

 

[Dennis Tate]

Here is another interesting argument:

(p1) A and (A implies B), therefore B;
(p2) B and (B implies A), therefore A;
(C) Therefore, A and B.​

I'll give a straightforward application of it:

(p1) God exists and the fact that God exists implies that the Bible speaks the truth, therefore the Bible speaks the truth;
(p2) The Bible speaks the truth and the fact that the Bible speaks the truth implies that God exists, therefore God exists;
(C) Therefore, God exists and the Bible speaks the truth.​

It's seriously more complicated than usual, so please take all the time you need to answer the two questions:

Question 1: Do you think that this argument is logically valid, and why?​

Question 2: Do you think that this argument is fallacious, and if so, what kind of fallacy is it?​

Thanks to all for your answers,

In my opinion String Theory.. .combined with the Law of Probability... combined with the Cyclic Model of the Universe and the new Multiverse Theory......
all help to add to Ezekiel chapter thirty seven, Revelation chapter twenty and Romans chapters nine, ten and eleven.... which......
hints at time being non-linear and our Creator organizing an essentially infinite number of Ezekiel chapter thirty seven style events in order to lead all of us to Eventual Universal Salvation.......

which.... would tend to verify your entire argument!? (I think)?!

h. Who goes to heaven?
In the end ... believe it or not (sigh of relief), everyone gets to come home! Heaven is a place of ultimate LOVE. When we have learned how to become individuals that base our entire existence and consciousness around manifesting LOVE, we then become capable of entering the domain of the higher Realms of Heaven. If we do not practice Love, we can only go so far and we will be made to incarnate somewhere out there in God's super Universe again and again (unlimited times) until we learn.
