Mark 12:43

(ubi sup.) It goes on, And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury: for God does not weigh the property but the conscience of those who offer; nor did He consider the smallness of the sum in her offering, but what was the store from which it came.

(ubi sup) Again, in an allegorical way, the rich men, who cast gifts into the treasury, point out the Jews puffed up with the righteousness of the law; the poor widow is the simplicity of the Church: poor indeed, because she has cast away the spirit of pride and of the desires of worldly things; and a widow, because Jesus her husband has suffered death for her. She casts two mites into the treasury, because she brings the love of God and of her neighbour, or the gifts of faith and prayer; which are looked upon as mites in their own insignificance, but measured by the merit of a devout intention are superior to all the proud works of the Jews.

But the Scribes used to come to women, who were left without the protection of their husbands, as though they were their protectors; and by a pretence of prayer, a reverend exterior and hypocrisy, they used to deceive widows, and thus also devour the houses of the rich. It goes on, These shall receive a greater damnation, that is, than the other Jews, who sinned. Now there was a praiseworthy custom amongst the Jews, that those who were able and willing should put something into the treasury, for the maintenance of the priests, the poor, and the widows; wherefore there is added, And many that were rich cast in much. But whilst many people were so engaged, a poor widow came up, and showed her love by offering money according to her ability; wherefore it is said, And there came a certain poor widow, and she threw in two mites, which make a farthing. Or else; That widow is the soul of man, which leaving Satan to which it had been joined, casts into the temple two mites, that is, the flesh and the mind, the flesh by abstinence, the mind by humility, that so it may be able to hear that it has cast away all its living, and has consecrated it, leaving nothing for the world of all that it possessed.

But in a mystical sense, they are rich, who bring forth from the treasure of their heart things new and old, which are the obscure and hidden things of Divine wisdom in both testaments; but who is the poor woman, if it be not I and those like me, who cast in what I can, and have the will to explain to you, where I have not the power. For God does not consider how much ye hear, but what is the store from which it comes; but each at all events can bring his farthing, that is, a ready will, which is called a farthing, because it is accompanied by three things, that is, thought, word, and deed. And in that it is said that she cast in all her living, it is implied that all that the body wants is that by which it lives; wherefore it is said, All the labour of man is for his mouth. (Eccl. 6:7)
