There are three key moments of divine and human hospitality in  our salvation history The Abraham pattern of divine and human hospitality recurs through salvation history. From the time of the promise made to Abraham, to its fulfilment in Christ, and at the Last Judgment, the Host of the world is welcomed and shown hospitality in three key moments by persons unaware that they were hosting him. Abraham hosting his three visitors, the Samaritan woman hosting Jesus at the well, and the blessed of the Father hosting the hungry and thirsty Son of Man, had no idea whom they were hosting. 1. Abraham at the time of the promise (Genesis) 2. The Samaritan woman at the fulfillment of the promise in Christ (John 4) 3. The blessed of the Father at the end of time (Matthew 25) In these three moments of salvation history, Scripture tells us that we encounter the Other in our hospitality to others. We encounter the Host of the world in our hospitality to strangers. Hosting those whom the Host of the world is hosting, we encounter the Host himself, the Origin, Ground and Destiny of all humankind!  The hospitality operative in these three key events, like grace of God, is purely gratutious, devoid of any calculating thought of recompense or quid pro quo. Had the hopitable persons known the importance of their Guest, the sheer gratuity of their hospitality might be in question.
