When I take Holy Communion in church on Sunday mornings, it involves eating a thin disc of bread and then sipping from a chalice of wine. As a Roman Catholic, I believe that this bread and wine, through some supernatural process, has transubstantiated into the body and blood of Jesus Christ. . . . in recent weeks, my local church has withdrawn the wine element as a precaution against the spread of swine flu. Given that it too believes in transubstantiation, the inference is that I might catch it from Jesus. Surely that strain would at least be self-healing.
