Prayer And Guests

Fratrem domum tuam introgressum ne sine oratione dimiseris - Vidisti, inquit, fratrem, vidisti Dominum tuum - maxime advenam, ne angelus forte sit. Sed nec ipse a fratribus exceptus priora feceris refrigeria terrena caelestibus; statim enim iudicabitur fides tua. Aut quomodo secundum praeceptum Pax huic domui dices, nisi et eis qui in domo sunt pacem mutuam reddas? Tertullianus, De Oratione, Caput XVI Source: Migne PL 1.1193b-1194a

Do not let not a brother who has entered your house depart without a prayer: you have seen a brother, it says, you have seen your Lord, especially if he is a stranger, lest perhaps he be an angel. 1 And when you are received by the brethren, do not give earthly refreshment precedence over the things of heaven, for immediately your faith will be judged. Or how will you, according to the command, say 'Peace be to this house,' 2 unless you also bring peace to those in the house and receive it?   Tertullian, On Prayer, Chapter 26 1 Heb 13.2 2 Lk 10.5
