Agree, but mostly disagree.

First off, the building is not the Church.  The building is the place where the Church gathers and is formed from Living Stones.

While the building (as a place we have declared hallowed and set apart) should not be a place for idle chitchat (at least outside the Narthex and Parish Hall). I do agree prayer and meditation should definitely occur there, it is a place primarily where the Body of Christ gathers and is sent forth from to take up the Mission of the Risen Christ.  

I have come to the conclusion that by focusing only on the Real Presence of Christ in the bread and wine (which I do not deny for one minute) to the near exclusion of the Real Presence of Christ in the gathered and sent community, we have come dangerously close to being guilty of ignoring Paul's admonition in 1 Cor 11:29 (Hint: Paul is NOT talking about Transubstantiation). I truly believe this is a large part why so much of the Church is sick or dying.
