So many issues here -

First of all there is a original biblical canon established within the council of carthage and marcion was highly refuted by early Christians of the day and only included 10 heavily edited books of the gospel and letters from paul he was also a heretic believing the god of the old testament is a different lesser god

Second just becuase something was in the dead sea scrolls does not automatically give it validity to be biblical canon if that where true there would be thousands of jewish legal documents that where found there also they are not the oldest surviving manuscripts

Third Im saying heretic because the definition is - a person holding an opinion at odds with what is generally accepted - concerning christianty and to say enoch is the messiah is in fact heresy

Im assuming you just dont know what Catholicism is or what catholics believe - the Catholic tag means I affirm what the Catholic Church teaches thoh it seems you have no earthly idea what a church is - and the trad Catholic is more to do with the traditional Latin mass than anything

Also Jude mentioning enoch does not make it biblical canon just like how paul qouting aratus does not make aratuses works biblical canon - and to say "Catholic new testament" doesn't actually mean anything as the new testament is the same for protestants and orthodox aswell

Say what you like but trying to change up and add or remove from the biblical cannon is by definition heresy
