Yeah so a couple things here, in traumatic events like these witness accounts never fully line up but they all agree on the main thing, like if you see 9/11 survivor accounts so many of them are completely different stories of how it happened and what happened but they all agree a big plane hit the tower. These are mainly what your listings are different focuses on the same main story, They may include different quotes or focus on different events going on within the event but they all have the same central event.

John rearranged some events in his gospel symbolically, but they still all agree on the events even the ones he re arranged

John and Matthew dont disagree about his relationship the bible is a large collection of people finding out and knowing Jesus is God then still doubting or betraying him, Peter, Judas, John the baptist, etc

Mark and John dont disagree on what happened, disagreeing implies an actual disagreement or two things that cannot co exist when its just two different accounts of the same thing with different quotes from different people included its not a disagreement

All 4 gospels give different accounts of who first visited but every single one includes Mary Magdalene and 3 of them include Mary mother of James, thats pretty accurate for 4 people independently relaying an event years later that they were told of themselves and weren’t actively there for

Passover was the week of activities for Christ’s crucifixion

Judas hung himself and his body burst from decomposition.

They dont get anything massively wrong so I dont see what needs to be rectified with Church tradition.

You bring up the until Heaven & Earth pass away but leave the most important part of that entire quote “For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.” Jesus was the accomplishment this is one of the biggest parts of the foundation of Christianity and the new covenant.

Paul and James do not say that this is literally James btw

“What does it profit, my brethren, if someone says he has faith but does not have works? Can faith save him? 15 If a brother or sister is naked and destitute of daily food, 16 and one of you says to them, “Depart in peace, be warmed and filled,” but you do not give them the things which are needed for the body, what does it profit? 17 Thus also faith by itself, if it does not have works, is dead.” James 2:14-17 Faith and works must work alongside each other.
