WHereas it hath pleased Almighty God in his late Providence towards His Majestie and His people , to manifest at once the glory both of his power and mercy , in giving His Majestie a happy Victory over His Adversaries at Sea , filling the hearts of His Maiestie and His people as full of joy and thankfulness , as becomes so transcendent a Mercy : We cannot upon due consideration thereof , but with all humility admire and adore the Mercy and Goodness of God in this His Signal manifestation thereof . And We look upon it as an invitation from Heaven to His Majestie and all His people unto most intire thankfulness for the same . And to the end some solemn time may be set apart for the publick performance of this Duty ; and that We and all His Majesties Subjects throughout this Kingdom , may pay our just tribute of praise and thanksgiving to Almighty God ; We do hereby publish and declare , and also strictly charge and command , That Tuesday the Fourth day of July next , be set apart and observed as a day of publick Thanksgiving , in and throughout this His Majesties Kingdom of Ireland . And We do also direct and appoint , That this Our Proclamation be publickly read in all Churches and Chappels on the Lords Day precedent to the said day of Thanksgiving hereby appointed ; to the end that notice may be taken thereof , and due thanks and praise may upon the said day be offered unto Almighty God . And that humble supplications be poured out before him , for his continual assistance and improvement of this , and all his mercies to the honour of his great Name , and the peace and benefit of His Majestie and His people , willing and strictly commanding all persons within this His Majesties Kingdom of Ireland , with all sobriety , reverence and thankfulness to observe that day , as becomes so solemn an occasion .
