Remigius of Auxerre
Catena Aurea · Matthäusevangelium 10
And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence. And when ye come into an house, salute it. And if the house be worthy, let your peace eome upon it: but if it be not worthy, let your peace return to you. And whosoever shall not receive you, nor hear your words, when ye depart out of that house or eity, shake off the dust of your feet. Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.
The Lord therefore taught his disciples to offer peace on their entering into a house, that by means of their salutation their choice might be directed to a worthy house and host. As though He had said, Offer peace to all, they will shew themselves either worthy by accepting, or unworthy by not accepting it; for though you have chosen a host that is worthy by the character he bears among his neighbours, yet ought you to salute him, that the preacher may seem rather to enter by invitation, than to intrude himself. This salutation of peace in few words may indeed be referred to the trial of the worthiness of the house or master.
