Jesus Christ did one better...He told His disciples where to find it all:
Luke 24:
44 Then He said to them, “These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” 45 And He opened their understanding, that they might comprehend the Scriptures.
46 Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, 47 and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. 48 And you are witnesses of these things. 49 Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high.”
And then later, after Pentecost the apostles started writing it down.
What did Jesus Christ give as an authority?
Matthew 4:
4 But He answered and said, “It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”
On Jesus' views of the traditions of the magesterium at the time of His earthly ministry:
Mark 7:
5 Then the Pharisees and scribes asked Him, “Why do Your disciples not walk according to the tradition of the elders, but eat bread with unwashed hands?”
6 He answered and said to them, “Well did Isaiah prophesy of you hypocrites, as it is written:
‘This people honors Me with their lips, But their heart is far from Me. 7 And in vain they worship Me, Teaching as doctrines the commandments of men.’
8 For laying aside the commandment of God, you hold the tradition of men —the washing of pitchers and cups, and many other such things you do.”
9 He said to them, “All too well you reject the commandment of God, that you may keep your tradition. 10 For Moses said, ‘Honor your father and your mother’; and, ‘He who curses father or mother, let him be put to death.’ 11 But you say, ‘If a man says to his father or mother, “Whatever profit you might have received from me is Corban”—’ (that is, a gift to God), 12 then you no longer let him do anything for his father or his mother, 13 making the word of God of no effect through your tradition which you have handed down. And many such things you do.”
Pretty clear Jesus Christ had a VERY high regard for His written and spoken words. The Pharisees' man-made traditions could not muster an appeal to the Sola scriptura responses of Jesus Christ.
And Catholics tell us to follow Jesus example right?
But where did Christ tell anyone to write anything down?
Where did Christ tell anyone that His Religion would be based on a book?
Matthew 4:1-11
Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. And after fasting forty days and forty nights, he was hungry. And the tempter came and said to him, “If you are the Son of God, command these stones to become loaves of bread.” But he answered, “It is written,
“‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’”
Then the devil took him to the holy city and set him on the pinnacle of the temple and said to him, “If you are the Son of God, throw yourself down, for it is written,
“‘He will command his angels concerning you,’
and
“‘On their hands they will bear you up, lest you strike your foot against a stone.’”
Jesus said to him,
“Again it is written, ‘You shall not put the Lord your God to the test.’”
Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory. And he said to him, “All these I will give you, if you will fall down and worship me.” Then Jesus said to him,
“Be gone, Satan! For it is written, “‘You shall worship the Lord your God and him only shall you serve.’”
Then the devil left him, and behold, angels came and were ministering to him.
Luke 4:1-13 And Jesus, full of the Holy Spirit, returned from the Jordan and was led by the Spirit in the wilderness for forty days, being tempted by the devil. And he ate nothing during those days. And when they were ended, he was hungry.
The devil said to him, “If you are the Son of God, command this stone to become bread.” And Jesus answered him,
“It is written, ‘Man shall not live by bread alone.’”
And the devil took him up and showed him all the kingdoms of the world in a moment of time, and said to him, “To you I will give all this authority and their glory, for it has been delivered to me, and I give it to whom I will. If you, then, will worship me, it will all be yours.”
And Jesus answered him,
“It is written, “‘You shall worship the Lord your God, and him only shall you serve.’”
And he took him to Jerusalem and set him on the pinnacle of the temple and said to him, “If you are the Son of God, throw yourself down from here, for it is written,
“‘He will command his angels concerning you, to guard you,’
and
“‘On their hands they will bear you up, lest you strike your foot against a stone.’”
And Jesus answered him,
“It is said, ‘You shall not put the Lord your God to the test.’”
And when the devil had ended every temptation, he departed from him until an opportune time.
“Pretty clear Jesus Christ had a VERY high regard for His written and spoken words.” Really? What did He write down?
Your quotes describe the necessity for Jesus to fulfil all prophecies. Too bad the Protestants threw away the Book of Wisdom (Wisdom 2: 12-20).
