Tiffany;
Sadly, I think that many in society need to create devils. They have a world-view that it's a cruel and inhospitable world, and you constantly have to stomp out evil to survive (or something like that.)
What if each person saw their lives filtered through an internal movie script? If your script-world had magic and miracles, you'd seize on random co-incidences to prove that magic did indeed exist. and if the script called for satan to appear, well, you'd just have to cast people into the role. And the role of satan/devil/demon looks kind of like a laundry list -- homosexual, sexual predator, pedophile, transsexual, president-with-cigar, etc. (It's amazing to me that embezzlers, environmental polluters, sweatshop-owners and other money stealers (to include politicians) get punished more for getting caught than for their theivery. But I rant...)
But in your case, I'd call what happened to you a 'miracle.' Against type, these relatives you described have turned out to be either accepting or without pre-judgement. Hallelujah!
You do have an opportunity to make hay whilst the sun shines. You can educate your relatives in what TS is, with out most of the pre-conceptual baggage you find in society in general, and literalist religion in particular.
