Ok so you believe in the Spirit-guided Tradition of the identification of the canon. Excellent. So why shall God have a problem guiding men to expound on other teachings without error? Why should I trust the same people to give me the inerrant canon but not any other teaching? Should I trust God only if He is using men to teach about the canon but nothing else? It does not make sense.
the comparison is weak , let us try a better comparison ;
should God speak from the clouds to humans , even THAT would be inferior to scripture !
why ?
because as scripture says , we have the more SURE word , which is scripture .
indicating that voices coming from clouds , or arriving in peoples heads is not the way we are to walk , it is too open to deception , unlike scripture .
2 Peter 1
[
17] For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
[
18] And this voice which came from heaven we heard, when we were with him in the holy mount.
[
19]
We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
more sure word than a voice from heaven ? where ? what more sure word ?
[
20] Knowing this first,
that no prophecy of the scripture is of any private interpretation.
[
21] For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
everyting outside of scripture is flawed , because it is not infallible ....
the argument that a few hundred Church Fathers who were not infallible somehow become infallible as a unit is illogical.
