Wow I do so hope that global communications are still available after Armageddon or that the society has trained carrier pigeons otherwise what will all those congregations in the outlying ccountries do? After all there aren't many specialists in the organisation to get things up and running.
This organisation is planning for economies of scale not for global recovery after an apocalypse. It is a business built on the gulible for the preservation of the greedy. I pity those putting their faith in it.
