[quote silvercosmopolitian]Now I am agnostic, but have only recently been exploring faith, so I probably cannot comment on C of E policy.
However, I don't understand why you are worried.
A lot of people find faith, ( of any perspective), adds great peace, meaning and fulfillment to their lives. Certainly, I find the idea there is a higher power than us mere mortals greatly comforting. Your sister may or may not convert to christianity, but if she finds peace, meaning, hope and fulfillment within the C of E, ( which is th enational religion, hardly a fringe religous sect), then I don't see why you would be worried. The C of E are not going to tell your sister to cut off contact with family, give all her earnings to them etc.
I also don't see the issues with her boyfriend being a creationist. Whilst I, ( and tbh 99% of the flly practicing Christians I know), do not believe the creation story is literal, I don't see why it would be harmful or a "red flag," for her boyfriend to take it literally. None of us know for certain how the world was created, and so I don't understand why her boyfriend believing what is actually a rather nice part of the bible is literal would be concerning ?
As for homophobic, well many people of many faith's, ( be that Jewish, Sikh, Muslim, Hindu , Catholic), believe that gay sex/ gay msrriage is wrong. I do not share these views, ( I am adhemently in favour of gay marriage), but have friends of different religions who truly believe this.Obviously if they were going around actively harassing gay people that would be completely wrong, but I just couldn't get upset that my sister's partner has sincerely held views about gay sex being against his religion, and goes about his buissiness quietly.
Also,if christianity was that homophobic, would that many mainstream U.K churches allow gay marriage:

You really don't see the fact that OP's sister goes quiet when her boyfriend enters the room and has ditched her gay friends as a red flag?
