15 But you who are such as this, cannot labour in the Church. For your eyes, overcast with the gloom of blackness, and shadowed in night, do not see the needy and poor. You are wealthy and rich, and do you think that you celebrate the Lord's Supper, not at all considering the offering, who come to the Lord's Supper Without a sacrifice, and yet take part of the sacrifice which the poor man has offered? Consider in the Gospel the widow that remembered the heavenly precepts, doing good even amidst the difficulties and straits of poverty, casting two mites, which were all that she had, into the treasury; whom when the Lord observed and saw, regarding her work not for its abundance, but for its intention, and considering not how much, but from how much, she had given, He answered and said, “Verily I say unto you, that that widow has cast in more than they all into the offerings of God.
For all these have, of that which they had in abundance, cast in unto the offerings of God; but she of her penury has cast in all the living that she had,” Greatly blessed and glorious woman, who even before the day of judgment hast merited to be praised by the voice of the Judge! Let the rich be ashamed of their barrenness and unbelief. The widow, the widow needy in means, is found rich in works. And although everything that is given is conferred upon widows and orphans, she gives, whom it behooved to receive, that we may know thence what punishment, awaits the barren rich man, when by this very instance even the poor ought to labour in good works.
And in order that we may understand that their labours are given to God, and that whoever performs them deserves well of the Lord, Christ calls this “the offerings of God,” and intimates that the widow has cast in two farthings into the offerings of God, that it may be more abundantly evident that he who has pity on the poor lends to God.
