Carry neither purse, nor bag, nor shoes: and greet no man by the way.
All Commentaries on Luke 10:4 Go To Luke 10
Cyril of Alexandria
AD 444
When preaching to people everywhere the Word that he spoke and calling the inhabitants of the whole earth to salvation, he requires them to travel about without purse, bag or shoes. They are to travel rapidly from city to city and from place to place. Let no one say that the object of his teaching was to make the holy Apostles refuse the use of the ordinary articles of equipment. What good or what harm would it do them to have shoes on their feet or go without them? By this command, he does wish them to learn and to attempt to practice that they must lay all thought of their livelihood on him. They must call to mind the saint who said, “Cast your care on the Lord, and he will feed you.” He gives what is needful for life to the saints. Commentary on Luke, Homily
