By the Protector▪ A DECLARATION OF HIS HIGHNESS FOR A DAY OF public FASTING AND HUMILIATION.  
AS it is the Duty, so it hath been the constant practice of the People of God in all ages, not only to take special notice of the Providential dispensations of God towards them, whether they concerned them as a Nation, or as particular persons, but also to meet the Lord in the way, both of his judgements, and of his Mercies, in a solemn manner, suitable to such Dispensations, to which the Lord hath been pleased to give such visible testimonies of his gracious acceptance, as hath been and still is a great encouragement to his people to make their addresses to him under the like providences. And as no Nation under heaven hath been exercised with more various and wonderful Providences than these Nations of England, Scotland and Ireland, so none have had more eminent experiences of the goodness of the Lord in the speedy and merciful returns he hath made to the prayers of his people; And therefore of all others, it becomes them to let no Providence of God go unobserved or unregarded, especially such as seem to carry upon them Characters of the displeasure of that God, from whom alone We have professed to all the world, We have received all Our mercies past, and that We depend on him alone for greater things, which are yet in his people's expectation. Upon these grounds, His Highness the Lord Protector and the Council, sadly reflecting on the late dispensation of Divine Providence, in removing from us His Highness the late Lord Protector, whom the Lord hath used as a choice Instrument for carrying on his Work, and under him to be both a Sun and a Shield unto those that fear the Lord abroad and at home (which they cannot but be deeply sensible of as a sore stroke of his mighty hand) as also in the general visitation of Sickness and great Mortality, which is now upon many parts of this Nation, hold it their duty to invite the people of these Nations to humble themselves greatly under the mighty hand of God, in the sense of the many great and crying sins of this Nation, which have deserved his sore displeasure, and to accept the punishment of their sins. And likewise to seek the Lord for a blessing upon His Highness and his Government and Counsels for the good of these Nations, that thereby the breach which he hath made upon us may be healed, and the present tokens of his displeasure removed, and that he will be pleased yet to continue his gracious presence among us, and delight in us as his people, that his own Work may by his assistance be carried on, and peace and truth may be established in the midst of us. For which purpose His Highness the Lord Protector, with the advice of his Privy Council, hath thought fit to set apart Wednesday the Thirteenth day of October One thousand six hundred fifty and eight, to be observed as a day of Solemn Fasting and Humiliation in all places within England and Wales, and the Town of Berwick upon Tweed, earnestly exhorting all the people of God in this Nation to cry mightily unto the Lord, and to wrestle with him by prayer and supplication for the ends aforesaid. And that the Ministers of the several Churches and Congregations, do diligently and conscientiously attend their duties on that day, as is suitable unto so solemn a work, and that they give notice hereof on the Lord's day next before the said Thirteenth day of October in their public Meeting-place, and read this Declaration on the said day. And His Highness doth hereby prohibit all Fairs, Markets, and all bodily labour in the works of men's callings, which may interrupt or hinder the Religious observation of the day aforesaid.  
Given at White-Hall this Twenty fourth day of September, in the year of our Lord God, One thousand six hundred fifty and eight.
