4 We ordain, therefore, that in each of your dioceses you assign a day on which public prayers will be offered to appease God's anger and on which through your priests you will admonish the faithful of this urgent need and exhort them to support by their prayers, good works and offerings every movement that is directing its forces fully and effectively for the succor of needy and abandoned children.
