“The RCC makes the claim that what they teach is not to be checked by scripture.”
Incorrect. His Church makes the claim that what it teaches is His Word.
“The inspired words of the Holy Spirit is what he was referring to.”
How do you know the Gospels are the word of God? Why do you believe the New Testament is authentic? On what authority do you rely?
I suppose you want the RCC to take a bow and receive praise from all over the universe for the Bible? And all of the writers were Catholic as well?
It says so in them
>> Why do you believe the New Testament is authentic?<<
Because the Holy Spirit testifies to that fact.
Acts 15:8 And God, who knows the heart, bore witness by granting them the holy Spirit just as he did us. 9 He made no distinction between us and them, for by faith he purified their hearts.
And I will ask the Father, and He will give you another Counselor to be with you forever--the Spirit of Truth. The world cannot accept Him, because it neither sees Him nor knows Him. But you know Him, for He lives with you and will be in you. John 14:16,17
>> On what authority do you rely?<<
Christ.
1 Corinthians 2:13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
16 For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ.
