John Cassian, Conferences XVIII–XXIV XXI.2: The exhortation of Abbot John to Theonas and the others who had come together with him

I am indeed delighted, my children, with the duteous liberality of your gifts; and your devout offering, the disposal of which is entrusted to me, I gratefully accept, because you are offering your firstfruits and tithes for the good and use of the needy, as a sacrifice to the Lord, of a sweet smelling savour, in the belief that by the offering of them, the abundance of your fruits and all your substance, from which you have taken away these for the Lord, will be richly blessed, and that you yourselves will according to the faith of His command be endowed even in this world with manifold richness in all good things: “Honour the Lord from thy righteous labours, and offer to Him of the fruits of thy righteousness; that thy garners may be full of abundance of wheat, and thy vats may overflow with wine.” And as you are faithfully carrying out this service, you may know that you have fulfilled the righteousness of the old law, under which those who then lived if they transgressed it inevitably incurred guilt, while if they fulfilled it they could not attain to a pitch of perfection.
