Scripture clearly states that Jesus did more than it contains and Jesus clearly states that He had much more to teach them...I tell you all this now, while I am still with you....
John 14 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
We do not blindly follow, we accept in faith, trusting Jesus.
If it is not written down in Scripture, how can it be followed? Faith cometh by hearing and hearing by the word of God. It is His holy Bible that contains His revelations to mankind. If you are not following the Bible, then you are following man-made doctrines and traditions. That is what you are accepting in faith, trusting Jesus that those doctrines and traditions are given by Him to fallible men to dispense to the Church. If Scripture cannot confirm what you are taught, then you are not being taught God’s word, which is Scripture.
“and bring all things to your remembrance,” does not mean that He is telling anyone other then the Apostles they will “remember”. It is only the Apostles who were with Him who can possibly “remember”. Surely you don’t expect us to believe that anyone who wasn’t there with Him would “remember” what He said and did do you? If that’s what the RCC says is justification for extra Biblical teaching it doesn’t square with what Jesus said. It’s preposterous to believe that anyone other then the Apostles would “remember”.

You can’t possibly be “trusting Jesus” in that instance because those that were not with Him could not possibly “remember”. In that instance you are trusting in the RCC, not Jesus.
