Mormons do not, IMHO, fall into the realm of Christianity...so that's a straw man question.
The Copts are Orthodox...so your question demonstrates an ignorance of Christianity.
And your answers demonstrate only a familiarity with cutting-and-pasting from Wikipedia/Answers.com. I look forward to you explaining to my Baptist friends (especially the "Independent" and "Fundamentalist" ones) how they're really Protestants with "firm roots in the Protestant Reformation initiated by Martin Luther's 95 Theses".
