Don't you think there is a difference between words and action? Scripture clearly says Jesus DID many other things that IF they had been written down, the whole world could not contain all that COULD be written. That is a far cry from insisting, as your church does, that Jesus SAID many things not written down and then attributing these "sayings" to Tradition that was orally passed down and equally binding on all Christians as his words were. They produce no real proof of what these unwritten sayings were.
If you notice, the Apostle John clearly stated that Jesus DID many things not written down BUT that what he DID write down was for their belief and salvation:
But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name. (John 20:31)
John reiterated this same thing when he wrote in his epistles:
These things have I written unto you that believe on the name of the Son of God; that you may know that you have eternal life, and that you may believe on the name of the Son of God. (I John 5:13)
The real question here is why would the Apostles have omitted writing things Jesus said to them if it affected our eternal life? We know that after Jesus ascended into Heaven, the Holy Spirit, as he promised them, would continue to reveal truth to them and we have that truth preserved in the books of the New Testament. Did the Holy Spirit forget something or leave something out that theologians only realized centuries later? I don't buy that.
you have to be kidding....Jesus was a human being and He said zillions of things that were not recorded...He didn't even know the apostles until He was an adult. How many wonderful things must He have said to His parents, relatives, friends, that we will never get to hear. Maybe one of His boyhood friends fell and was injured...perhaps Jesus wiped away the injury and comforted His friend.....they were ten years old, chances are that it didn't make the big book. For you, or anyone, to claim that everything that Jesus said was somehow recorded is nonsense!!!
