Various relative duties
Flee from haughtiness, “for the Lord resists the proud.” Abhor falsehood, for says [the Scripture], “You shall destroy all them that speak lies.” Guard against envy, for its author is the devil, and his successor Cain, who envied his brother, and out of envy committed murder. Exhort my sisters to love God, and be content with their own husbands only. In like manner, exhort my brethren also to be content with their own wives. Watch over the virgins, as the precious treasures of Christ. Be long-suffering, that you may be great in wisdom. Do not neglect the poor, in so far as you are prosperous. For “by alms and fidelity sins are purged away.”
