4 In days gone by our dear widow was extremely fastidious in her dress, and spent whole days before her mirror to correct its deficiencies. Now she boldly says: “We all with unveiled face, beholding as in a glass the glory of the Lord, are changed into the same image, from glory to glory, even as by the spirit of the Lord.” In those days maids arranged her hair, and her head, which had done no harm, was forced into a waving head-dress. Now she leaves her hair alone, and her only head-dress is a veil.
In those days the softest feather-bed seemed hard to her, and she could scarcely find rest on a pile of mattresses. Now she rises eager for prayer, her shrill voice cries Alleluia before every other, she is the first to praise her Lord. She kneels upon the bare ground, and with frequent tears cleanses a face once defiled with white lead. After prayer comes the singing of psalms, and it is only when her neck aches and her knees totter, and her eyes begin to close with weariness, that she gives them leave reluctantly to rest.
As her dress is dark, lying on the ground does not soil it. Cheap shoes permit her to give to the poor the price of gilded ones. No gold and jewels adorn her girdle; it is made of wool, plain and scrupulously clean. It is intended to keep her clothes right, and not to cut her waist in two. Therefore, if the scorpion looks askance upon her purpose, and with alluring words tempts her once more to eat of the forbidden tree, she must crush him beneath her feet with a curse, and say, as he lies dying in his allotted dust: “Get behind me, Satan.” Satan means adversary, and one who dislikes Christ's commandments, is more than Christ's adversary; he is anti-christ.
