Laura Ruth ,
For Coptic specific questions, May I recommend that you go directly to our Oriental Orthodox Discussion Forum that is moderated by Salpy . You will get many more responses there from members of the Oriental Orthodox churches. I have found it to be the place to go to learn more and get direct answers about the Coptic and other Oriental Orthodox Church beliefs. Salpy, Mina, and others who post there provide excellent resources , as well as, correct citations from leading Oriental Orthodox theologians and leaders.
