Theophylact of Bulgaria
When encountering individuals who refuse to accept their message, they were instructed to shake the dust from their feet, as commanded by the Lord. This act served as a testament that they had journeyed far for the benefit of those individuals, yet found no gain, symbolizing that they took nothing from them, not even the dust on their shoes. Instead, they expelled it, which would stand as a witness against those who rejected them, acting as a mark of shame. Truly I say to you, it will be more tolerable for Sodom and Gomorrah on the day of judgment than for those who do not welcome you. The inhabitants of Sodom, having faced punishment in this life, will experience a lesser judgment thereafter; the apostles were not sent to them. In contrast, those who turn away from the apostles will endure greater suffering than the Sodomites.
