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.
Otherwise; The feet of the disciples signify the labour and progress of preaching. The dust which covers them is the lightness of earthly thoughts, from which even the greatest doctors cannot be free;their anxiety for their hearers involves them in cares for their prosperity, and in passing through the ways of this world, they gather the dust of the earth they tread upon. They then who have despised the teaching of these doctors, turn upon themselves all the toils and dangers and anxieties of the Apostles as a witness to their damnation. And lest it should seem a slight thing not to receive the Apostles, He adds, Verily I say unto you, it shall be more tolerable for Sodom and Gomorrah in the day of judgment, than for that city.
