Well, the HS does not require reasoning or discernment, so that means the reasoning and discernment is yours.
The HS gives the discernment to Reason. If he didn’t give it, the reasoning would purely be our own (subject to personal interpretation).
That being the case, you are the final authority on whether you have heard the HS or not.
Our belief and faith in God shows this statement to be wrong. Again, the HS working through one is the authority. How else would we have been given the canonized Scriptures?
I am glad we can agree on this point. This being the case, what makes you think you can apprehend what He wants you to know through puny human wisdom??
Tell that to your magisterium.
No, I must confess, Roman Catholics are often a great mystery to me.
