Jesus said that he was not even good but only the Father.
I think Jesus understood Adamic sin and tried to help people understand how to become better. Luke 6.
All has fallen short and think God we are under Gods Grace.
Although I enjoyed your post I do not agree with modern thinking. The most important New Testament teaching is about: Sin entered the world because of Adam and Eve rebellion. Adam and Eve were perfect but because of their sin their offspring were born imperfect and sinners. Important teaching:God love the world so much they he gave his only Begotten son.
Adamic sin or practicing sin? Even Paul wrote about practicing sin. How many times do we need to sacrifice Jesus.
I enjoyed reading Jesus sermon in Luke 6. But I do not agree with picking the bible apart to see which came first! Granted a few are making money.
ONE thing that John 5 proves is that many knew this man was healed by Jesus. A good testimony of Jesus Christ and God!
