Well, according to Yeshua, it is true that only scripture was given by inspiration of Yehova, but that was not the question that I intended to answer.
Traditions of men are roundly condemned by Yeshua, and by his words, only those whose righteousness exceeds that of the men that promote traditions will find his Father’s rest.

Matthew 16 16:17 - [16]Simon Peter answered and said: Thou art Christ, the Son of the living God. [17] And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven.
I find this interesting. So is that to say that when Peter said the above-mentioned he was not inspired by God? Isn't the profession itself inspirational? Or, rather, it became inspriational only as a result of being recorded in Scripture?
I think this is one of the fundamental flaws of protestantism. It tends to forget these were real people and real events. In some way it's like a protestant version of the modern "picutres or it didn't happen," mindset.
