6 Let us give heed to our Lord, our True Example and Succour. Let us prove that He is our Succour; “Without Me ye can do nothing.” Let us prove that He is our Example; “Christ,” says Peter, “suffered for us, leaving us an example that we should follow His steps.” Our Lord Himself had bags in the way, and these bags He entrusted to Judas. It is true He suffered from the thief; but I as desiring to learn of my Lord say, “O Lord, You suffered from the thief, whence had Thou that of which he could take away? Me, a wretched and infirm man You have admonished not even to carry a purse; You carried bags, and had that in which You could suffer from the thief. If You had not carried them, neither could he have found anything to take away.” What remains, but that he here says to me, “Understand what that you hear, 'Carry no purse,' means? What is a purse? Money shut up, that is, concealed wisdom. What is, 'Carry no purse? Be not wise within your own selves only. Receive the Holy Ghost.' It should be a fountain in you, not a purse; from whence distribution is made to others, not where it is itself shut in.” And the scrip is the same as the purse.
