6 For the present therefore let us lay aside our excessive sumptuousness, and let us endure moderation, and learn to acquire by honest labor all that we are to have: since even the blessed John, when he was discoursing with those that were employed upon the tribute, and with the soldiery, enjoined them “to be content with their wages.” Anxious though he were to lead them on to another, and a higher self-command, yet since they were still unfit for this, he speaks of the lesser things. Because, if he had mentioned what are higher than these, they would have failed to apply themselves to them, and would have fallen from the others.
For this very reason we too are practising you in the inferior duties. Yes, because as yet, we know, the burden of voluntary poverty is too great for you, and the heaven is not more distant from the earth, than such self-denial from you. Let us then lay hold, if it be only of the lowest commandments, for even this is no small encouragement. And yet some among the heathens have achieved even this, though not in a proper spirit, and have stripped themselves of all their possessions. However, we are contented in your case, if alms are bestowed abundantly by you; for we shall soon arrive at those other duties too, if we advance in this way. But if we do not so much as this, of what favor shall we be worthy, who are bidden to surpass those under the old law, and yet show ourselves inferior to the philosophers among the heathens? What shall we say, who when we ought to be angels and sons of God, do not even quite maintain our being as men? For to spoil and to covet comes not of the gentleness of men, but of the fierceness of wild beasts; nay, worse than wild beasts are the assailers of their neighbor's goods. For to them this comes by nature, but we who are honored with reason, and yet are falling away unto that unnatural vileness, what indulgence shall we receive?
Let us then, considering the measures of that discipline which is set before us, press on at least to the middle station, that we may both be delivered from the punishment which is to come, and proceeding regularly, may arrive at the very summit of all good things; unto which may we all attain, by the grace and love towards man of our Lord Jesus Christ, to whom be glory and dominion for ever and ever. Amen.
