Christian Scientology advice...

I've inadvertently invited a couple who are seriously into Christian Science to a social gathering which I am helping to host. I wasn't aware of their beliefs until someone mentioned that they are into it. Is there anything I should avoid mentioning or doing which may cause offence. I'm hoping that I can avoid conversation with them altogether but in the event that this doesnt prove possible wanted to cover off all eventualities.
Does anyone know if they drink or what they can or cant eat etc?Any advice gratefully accepted.
