Offer them the basic book "The Orthodox Church"...they will let you know if their interested
After that, tell them about your Church and if possible bring them. Just be a typical friendly Copt. :-) I would hammer home the emphasis on mysticism whereas Rome focuses on strict legal definitions with rewards and penalties. Also explain why your Patriarch uses the title "Pope."
Be sure to include that Alexandria was the original Pope, beeing GIVEN the title centuries before the archbishop of Rome ASSUMED it.
And yes, I would say play it by ear, but try to get them to attend a service. Even seeing the Church (depending on what your Church looks like) could help.
I wouldn't recomend "The Orthodox Church" anymore. But "The Orthodox Way" is still good.
