You can believe some authority by reason. But if the source of the authority cannot be grasped by reason alone then you cannot by full reason believe in that authority. Your heart must be beguiled by the far side of reason.
There is no such natural need to grasp a SOURCE of authority.
Take the example of an astronaut who has walked on the moon. Let us say that in our town, no one else had done that and there were no astronauts. If I wanted to know what it is like on the moon, to walk on it, my best authority is the Astronaut. I don’t ask if he got this authority from God or You someone else. For my understanding, it is sufficient that he be someone who demonstrated reason to think he has that knowledge.
Same here. There is no postulation of a supernatural authority or existence of God in the OP argument. We only think that Christ has authority over Transcendent matters because of his demonstration through his death and resurrection. He did not have to do this multiple times to prove that it was not a random event because there are no other accounts with sufficient level of witness to someone getting killed and rising from the dead.
So your entire counter argument is invalid because it postulates something that the OP argument does not require.
Have I not confirmed this?
Now that I understand you better, I think you have confirmed this. You think this is true and you also think that even the Catholic Church cannot establish its authority on reason alone. That part is false for the reasons I discussed above. Your postulation that we need to assume the existence of a Transcendent authority as a source etc. are false.
But there is something even more erroneous in your conclusion. You therefore conclude that this is proof that reason alone is insufficient for one to come to arrive at assenting to Christianity. That is a logical error. Just because there are no reasons for assenting to Christianity as an authority does not mean that I have justified use of faith. All you would have done is demonstrate that Christianity is unreasonable to assent to (not a very good conclusion I might add for any Christian).
The good news is that your conclusion is invalid anyway because your initial assumption or understanding of the OP is flawed. You have assumed that authority always needs another source. It is not the case in the event where the authority is demonstrable.
So in this case, the authority if Christ was demonstrated by his death and ressurection. As to whether he received the ability and authority over the Transcendent laws themselves from himself or by someone else is itself part of Divine revelation that he must reveal. **Without knowing he is a valid authority to assent to, we would be unreasonable to believe any of his claims, one way or the other. **
Please let me know if things are clearer now.
If you want to tell me what I believe I suppose you have the right to do so, it would be worthless but you can do it. Now what is of worth is if I tell you what I believe. That is faith and reason convict my heart of truth, where reason alone is insufficient for completion. It beguiles me to finish it.
Faith can give you certainty over time on the reason for assent, yes. But if something was wrong in the reasoning itself, then you must doubt that faith, and you would be reasonable to do so.
Otherwise you will be convinced of an error.
Now, the crux of your argument is that you have authority by reason. Which I will give you here. “Christ gave you the authority”. Now you must prove that Christ had the authority to do so by reason alone.
As I said above, this is your primary error in understanding what has been said here. We do not see Christ as having gotten authority from someone. The authority you speak of is more the ability to govern the natural laws and Transcendent laws. Though Christ has demonstrated he can do so, we do not care if he has derived this authority from a higher power or by himself. That is irrelevant. If the Astronaut reached the moon, walked and came back, we do not care about who provided the technology for him to get there to think of him as an authority regarding moon walking or being in space.
Same with Christ. How or who is established his miracles are not our concern. The fact that he could do so simply provides us with reason to believe him as knowing the Transcendent. It is the knowledge we seek first. Not the ability.
If you cannot do this by reason alone your claim against “faith and reason” is invalid. If you try to accept the evidence by reason alone you will have to accept many religions. Remember, none of the sources have authority, it was the authorities in all their wisdom that denied Him.
As far as my involvement in this thread I am claiming nothing but the importance of faith and reason. So you can stop handing me my beliefs and treating me like a dirty protestant. It’s not relevant where I come in.
Well, what I am demonstrating here is that you cannot assent on faith and reason. By faith, I specifically mean faith in Transcendent truths and claims other than its existence.
You can assent and then have faith but not before. I have explained why to you above and I am looking forward to hearing your reply.
P.S. It is also worth noting that you cannot demonstrate to me that one needs Faith and Reason for assent. Because in order to show me that you need Faith as well, you must first be sure that the particular religion that requires such form of assent is TRUE. But since that itself is the question under test, you argumentation will always be circular and hence fallacious.
