Much of the words Jesus really uttered might not have reached us and what has reached us could not have been originated from Jesus. For example, eagle-eyed Jeremiah could declare that what was circulating during his time as ‘The Law of Jehovah in fact was falsehood or deception of the lying pen of scribes or of the dishonest scribes.’ (Jeremiah 8:8, Berean Study Bible; Christian Standard Bible; Good News Translation)
Jesus who had even sharper eyes than Jeremiah and also anointed by holy spirit would even use sharper words to describe the invalidity of that Law than Jeremiah did. Such words would not reach us because Law was made for the benefit of religious establishment—a fact that is well-attested alike in all the four gospels. (Matthew 21:12–17, Mark 11:15–19, and Luke 19:45–48; John 2:13–16). That means Jesus being depicted as a strong advocate of Law is a later adoption of the same religious establishment. Yet, words that show his real view of the Law could not be eliminated from the Bible. For example, Jesus simply cancelled Law when he said Mathew 7:12; 9:13; 25:31- 46 …etc.
The above conclusion is further reinforced when we look at the spurious context in which the Law was supposedly received, in the Sinai desert following the deliverance of the Israelites from Egypt: The depiction about the Hero of the whole episode, God, doesn’t match with His actual personality, with what He has already done in the nature. His style is so majestic that He cares for more than what is just required. Look at one of His acts—our planet home. It is more wonderful than it is convenient, more beautiful than it is useful. God could provide only what would remove our hunger and thirst—yet look at the variety of each fruit (as much as 7500 in the case of apple with bananas, grapes, strawberries and clementines coming after …), flower ……..etc. In the backdrop of this, you read Exodus. The way many times Israelites had to quarrel for their basic needs such as food and water shows that this God of the universe was nowhere in the picture. (Exodus 17:2) At one point they were even about to stone Moses (Ex 17:4). If God was really leading them, He would have taken care of not only their very basic needs but even more, without even anyone asking for them (Mathew 6:8)
