For a moment, try saying it this way: Christianity is a meal-fellowship. I know there are other ways to speak of the Christian movement. But, for a bit, I invite you, try this one. At root, Christianity is not just an idea. It is a specific meeting around food and drink. It is first of all not a religious inclination that an individual might have, not a philosophy nor a technique to equip an individual to engage with spiritual realities. In any case, it is certainly not a consumer good that an individual might or might not choose to buy in the marketplace of religious ideas. Rather, quite concretely, quite physically, Christianity is a meeting. Or, more profoundly, Christianity is a very specific kind of meeting: it is a meal-fellowship. As such, it is an invitation for us together to see both God and the world anew from the perspective of that table, of that shared food.
