It's interesting that you quote the scriptures pertaining to the same incident 3 times. And yet not one of them is saying what you claim. Where does the scripture say Jesus fulfilled the Sabbath?
Since when has the word fulfill meant changed, altered, switched, abrogated, cancelled, adjusted, or finished? In the sermon on the mount Jesus said He didn't come to do away with the law, but to fulfill. I would very much like you to reason this in a way that defends your contrary take on the concept of fulfilling.
So long as I reject this fact? Really? As if I am the one who is acting contrary to scripture? A "fact" doesn't become a fact as a result of repeated assertions. Why would I not reject something that you've made up? Sunday 'sacredness' and the rejection of the 4th commandment as written by the finger of God is a Catholic tradition with no foundation in scripture, and Protestant loyalty to Sunday is an act of submission to Catholic authority, not scriptural authority.
The council of Trent settled the argument in favor of the Catholic Church that tradition superceded scripture by clarifying the fact that it was the Catholic Church that changed the day from the 7th day to the first day. This gave Catholics the upper hand against the Protestants who were promoting Sola scriptura, the Protestants themselves holding to tradition contrary to the scriptures in their observance of the 1st day of the week, Sunday. You can read all about it by googling Council of Trent, Archbishop Gaspare Ricciullo del Fosso . Read his speech and how he confirmed tradition as the superior source and standard for faith and practice for the Catholic Church.
Your pretensions that Sunday sacredness or rest and the cessation of the Sabbath are based on scripture are just that.... Pretensions, and your own church admits as much in it's most prestigious council.
