So like Jewish instead of Catholic?This is exactly what I already described to debunk your exclusive use of the word "canon". Different churches have different books they consider canon. Who is the authority? Both churches will say they are. Who are "they"? The people in that church. Who are those books canon to? The people in that church who have decided certain books are canon.
At any time I can form my own church and declare different books as the "religious canon". As a matter of fact, I can do that without forming a church.
That's the point. "Canon" is a general term. It has next to no meaning until you declare what the subject is and to whom it is being applied. Canon: "accepted group or body of related works". You have to define who is accepting it, and what it is they are accepting. What is the Official Canon of Star Wars? That changes as is defined by the owner of the IP. So when Lucas sold the IP, Disney increased the scope of what is the Official Star Wars Canon. What I personally consider canon or to say, my personally accepted group or body or related works, may or may not be related to or based on the Official Canon. That's why one's called personal and the other is called official.
