Church of God, Inflationist

Inflatable infrastructure for churchgoers has arrived on the sandy beaches of Sardinia, as a bouncy chapel has been installed for Christians on holiday. "Using compressed air it takes only five minutes to inflate," the Times reports, and it "comes complete with an altar, an apse and a confessional."
Inflatable mosques and temples will be next. An inflatable sacred grove for druids.

The size of your church is directly affected by how much money you can raise – because the only pumps strong enough to inflate the whole structure cost $50,000 or more. Once you get that far, though, you realize there are still more rooms and radiating chapels to inflate... but it takes an even larger – and far more expensive – air pump.
Yet, even then, you find more – nearly impossible to inflate – rooms hidden away inside the structure.

"Who made this thing?" you ask one day, quietly, not wanting to draw attention to yourself; and you learn that there is a Holy Lab of Consecrated Inflatables housed in an unmarked room in the Vatican attics – attics the size of basketball courts – where priests trained in the art of shaping warm air read apocryphal texts on the breath of God, stitching vast sheets of polyethylene together to form Gothic geometries.
It's rumored that the largest inflatable ever created is being designed by the monks of Mount Athos; it will require a small nuclear power plant to fill properly.
Bombproof churches will be erected throughout Syria in what becomes known as the Inflatable Crusade.
In particularly expensive models, assembled by private firms in the Netherlands, inflatable priests will pop out of hidden compartments in the floor when you twist small valves, triggering a recording of Agnus Dei.
Children clap, endless cupolas unfold into the sky, and the real services of the evening begin.
