How could I be a cult? I revere no one as leader but Christ. I have no followers. Not one of those things on the list applies to me. On the other hand most apply to the RCC.
Easy! A cult is a religious group originating as a heretical sect and maintaining fervent commitment to heresy. Your heretical beliefs are a foundational beginning. And, using your list, correct me where I err here:
It is your own authority that determines Holy Scripture. You claim special authority, divine revelation in that the Holy Spirit through you interprets Holy Scripture correctly - all other interpretations are incorrect, according to the Holy Spirit (according to you).
You are intolerant of any and all other authority than yourself. You alone determine who Christ is, what following Christ means, and what 'revere' means, what worship means, etc. etc.
I can't know but suspect that there are those whom you influence, who "follow" you; however, every cult starts with one, some may remain that way, to the dismay of the would-be leader.
As to your list's "Dressing differently, sometimes in special uniforms or costumes"... well, I bet you have some of those in your closet. I don't, but some say I wear funny clothes. :)
