2. dude, pretty sure you need to leave that church. do some bible study on your own, then look for one that sounds like what you're reading about, something that's trying very hard to follow those guidelines. For starters, anything with Priests that isn't running on Mosiac law already has some signifigantly unscriptural organizational problems. And if it is Mosaic law, you might want to inform them the messiah came already, the law to prepare us for him has fulfilled it purpose, they need to migrate over to the final version.
The reason to move, other than the doctrine issues is that either the accusations are true, or the church is dysfunctional enough that their reputation is so bad the accuser thought a lie would stick. Both are bad, and just the event happening at all betrays a lot of cohesion issues.
