Catena Aurea · Lukasevangelium 10
Go your ways: behold, I send you forth as lambs among wolves. Carry neither purse, nor scrip, nor shoes: and salute no man by the way.
Our Lord also would have nothing human in us. For Moses is bid to loose off the human and earthly shoe when he was sent to deliver the people. (Exod. 3:5) But if any one is perplexed why in Egypt we are ordered to eat the lamb with shoes on, (Exod. 12:11.) but the Apostles are appointed to preach the Gospel without shoes: he must consider, that one in Egypt ought still to beware of the serpent’s bite, for there were many poisonous creatures in Egypt. And he who celebrates the Passover in figure may be exposed to the wound, but the minister of truth fears no poison.
