We have been given a function in the New Covenant, not a form. The modern mall was not so designed as to be an ungodly as possible, but to be as economic and functional as possible. And so it is no wonder to me that a church seeking functionality and feasibility should build a building resembling such functionality...But as we've indicated before, if the point of evangelicalism is, I don't know, evangelism, then McChurches aren't very practical at all.
If a stadium is the mot economical and functional way to include 40,000 people in an experience, then why would not Lakewood church (of which I am no fan) not use a stadium for a different kind of experience for 35,000?
There are reasons besides conformity that modern evangelicals have caved into functional practicality, and it is mainly because it is functionally practical.
Asks another commenter: "How many cathedrals have been built with the purest of intensions and lavished with gilded accoutrements only to end up host to a Godless mass of ritual?" I'm not sure what this "Godless mass of ritual" is - it sounds frightening - but just imagine how much worse it would be in a profoundly ugly building.
