"The common cup is, well, gross to many Christians because they don't like the idea of drinking after strangers. That's just the point. You're not drinking after strangers. You're drinking after your own flesh and blood, your family. And the offense is precisely the issue. You're recognizing Christ Jesus, discerning his Body, in the 'flesh' of his Body the church around you. If drinking after your brothers is 'disgusting,' then how much more eating Jesus' flesh and drinking his blood. That was disgusting to an assembly a while back as well."
