"This breaking of the limitations of hospitality to a small in-group, of offering it to the broadest possible in-group, and saying, you determine who your guest is, might be taken as the key message of Christianity. Then in the year 300 and something, finally the Church got recognition. The bishops were made into something like magistrates. The first things those guys do, these new bishops, is create houses of hospitality, institutionalizing what was given to us as a vocation by Jesus, as a personal vocation, institutionalizing it, creating roofs, refuges, for foreigners. Immediately, very interesting, quite a few of the great Christian thinkers of that time, 1600 years ago (John Chrysostom is one), shout: "If you do that, if you institutionalize charity, if you make charity or hospitality into an act of a non-person, a community, Christians will cease to remain famous for what we are now famous for, for having always an extra mattress, a crust of old bread and a candle, for him who might knock at our door." But, for political reasons, the Church became, from the year 400 or 500 on, the main device for roughly a thousand years of proving that the State can be Christian by paying the Church to take care institutionally of small fractions of those who had needs, relieving the ordinary Christian household of the most uncomfortable duty of having a door, having a threshold open for him who might knock and whom I might not choose."
