I think the biggest thing is clean as you go. Wash all your knives cutting boards dishes when you are done cooking not look at a sink full of dishes after you are done. Cleaning as you go helps keep away cross contamination and you avoid having food borne bacteria.
I think that the core doctrines of Christianity - the incarnation the resurrection life after death-these are as strong as ever. In fact the belief in life after death has increased in this century.
