The PROTESTANT's Warning-Piece: Or, The humble Remonstrance of Jeffery Corbet Citizen and Grocer of London, composed for the view of his Highness, the Parliament, and all the good People in England, Scotland and Jreland; and published to frustrate the designs of the Incendiaries employed by the Pope, and the King of Spain, who have several years contrived to fire the City of London in a 100 places at once, and then proceed to their long intended Massacre.  
Showeth,  
THat about the year, 1639. The Pope and his council sent William Oconner, an Irish Jesuit unto the King of Spain and the rest of the Catholic Princes for their contribution of Money, Arms and ammunition to carry on the Massacre of all the Protestants in the 3. Nations. And for that end the said Oconner came over into England about July, 1640. And went daily in the garb of a Courtier attending upon the Queen Mother. About 1. Septemb. 1640. the said Oconnee did boast unto an Irish convert that he was the chief contriver of that intended Massacre, and that there were 7000. men in private pay for the Massacre in London. And that the L. Cottington was to be Lieutenant of the Tower, and had 500 Irish Papists sent out of Flanders to guard the Tower under him. And that the Queen was to go beyond Sea, and pawn the jewels of the crown for that purpose. And that the Money, Arms, and ammunition which the King of Spain had sent over was secured at the Spanish Ambassadors house in London, and was disposed of amongst the Papists by one garret Dillon an Irish Jesuit, who had his Residence at the Spanish Ambassadors.  
That upon discovery of the Massacre the said O conner was apprehended, and committed to the gate-house, 3. Septemb. 1640. But divers persons in and about the City of London, and West minster, caused the said O conner to be protected from justice above 4. years and then to be released, contrary to the Law of God, and the laws of the Land. And though the said O conner was so timely apprehended that the Massacre was prevented here, yet because justice was not speedily executed upon him that others might hear & fear, and do no more so wickedly. Therefore the hearts of his Confederates were fully set in them to do evil. Insomuch that above 100000 Protestants in Ireland were barbarously murdered in cold blood several months after the said O conner was apprehended. Moreover those persons did not only prevail, that the bloody Massacre was not at all discovered to the Protestants in Ireland to forewarn and arm them to fight for their lives; but they improved such an Interest here, that the Popish party who had a hand in the Massacre intended in England were never searched out. Yea those persons wittingly and wilfully suffered the Queen to go beyond Sea to pawn the Jewels of the crown for laying the foundation of the late wars here to carry on the Pope's hellish Interest.  
That those Persons have from time to time, Protected the Pope's Agents from justice, when they were apprehended by his Highness, and others during the wars, and sent to the Parliament, to be tried for their lives as traitorous Incendiaries. Insomuch, that the Pope & his Conclave finding such encouragement they sent over 300 chosen Jesuits into England to make factions, and parties amongst Professors, and so preach us into Confusion as they have boasted. Moreover the Pope caused his bulls to be hanged up on the Church doors at Antwerp and other places, in 1643. and 1644. giving dispensations to all Priests, and Jesuits to come into England and to transform themselves into the various forms of Religion amongst us, the better to divide the People and carry on their bloody designs under a form of Godliness. And by that stratagem they have all along exasperated the spirits of Professors differing in judgement and made them bite, and endeavour to devour one another. Mean while the Pope's interest hath gone on unsuspected. And under this colour they have conspired divers years to set the City of London on fire in a hundred places at once, and then fall to Massacre, and cut off the root and branch of all the Protestants in these Nations. Yea, they have boasted that they are in constant readiness, and watch only for the remove of the Army as they did in 1648. upon the Scots Invasion, and the Insurrection in Kent Wales, &c. And the Captain general for that bloody work had his constant resident at the Spanish ambassador's house till he removed from London.  
That the aforesaid Persons have from time to time dammed up Justice against the Discoverers of those horrid Conspiracies, and all others who have appeared on their behalf. And have caused them and their friends to be defrauded of Estates above 40000. pounds in value. Mean while they have caused divers friends to those discoverers to go with sorrow to their Graves, and others to lead languishing lives in disgrace and repreach. Upon which account the foresaid Persons being subtle secret Enemies did improve such an Interest in the three last Parliaments, that no Law was made to remedy such abominable obstructions of justice whereby the Agents for the Pope, and the King of Spain, and the King of Scots have been encouraged, and protected in their barbarous Conspiracies, and the friends of the commonwealth exposed to ruin. Only the good hand of Providence hath preserved those Discoverers, and many of their friends even to Admiration for to make good the foregoing particulars on behalf of this divided, and well-nigh distracted commonwealth.  
That the King of Scots hath many years since engaged to the Pope to set up Popery in these Nations upon the Pope's engagement to improve his Interest to settle him in his Throne. And from that mutual engagement, The Presbyterians in Scotland, and here may gather that their making a party to bring in the K. of Scots for the Establishing of Presbytery was to strengthen the hands of the Pope's party to murder them, and their posterities. And the Protestant Cavalier may likewise observe that if they should have conquered the Parliaments party, yet all the advantage they would have gained thereby would have been only this to have been last destroyed. For the Pope's bloody Monsters would have given them no more quarter than they did the 100000. in Ireland, which they murdered in cold blood.  
That the Spine saith. No prophecy of Scripture is of any private Interpretation. And because thou hast let go out of thy hand a man whom I appointed to utter destruction, thy life shall go for his life, and thy People for his People. And neglect to strengthen the hands of the poor and needy, was one of the sins of Sodom, And God abhors solemn Fasts, and other duties where judgement and Righteousness are neglected, (2 Pet. 1. 20. 1 King. 20. 42. Ezek. 16. 49. Isa 1. 11. to 18. Amos, 5. 21.) From whence it doth appear that the unparalleled mercies which God hath bestowed upon these Nations have been hitherto intermixed with dreadful judgements threatening utter desolation. Because! The Pope's bloody Monsters have been let go from time to time by the aforesaid secret Enemies. And, because men of known Integrity, fearing God, and of a good conversation are not appointed for Commissioners to bring these secret Enemies unto speedy public Justice, and to break the heavy yoke of oppression by delivering the spoiled from their oppressors and strengthen the hands of the poor and needy, which is the faft that God hath chosen, and promised a special blessing unto.  
In tender consideration of the premises i do earnestly beseech all Protestants under what form whatsoever, specially in, and about the City of London, and West minster (as they will answer it at the great day of Account, and desire to be free from the blood of themselves, and their Wives, Children and friends.) That they would unite as one man, and improve their utmost Interest in the Parliament by Petition and otherwise, for the obtaining of such Commissioners, to the end the Innocent blood which hath been spilled by the treachery of those secret Enemies may be expiated, and the Pope's bloody designs now on foot may be defeated. And that the complainings in our Streets may cease by setting the oppressed free from the obstructions of justice which they have long groaned under. And I do hereby engage my Life to make good the aforesaid particulars before such Commissioners, and do profess before God and men that i am moved to declare these things out of no self-end or by-respect whatsoever, but out of a desire to discharge a good Conscience and a zeal to promote the good and welfare of these Nations; being fully convinced that the appointment of such Commissioners would soon root out the Pope's Incendiaries, and undeceive many thousands of deluded dissenters, and reconcile this divided People and open an effectual door for judgement, & righteousness to run down like a mighty stream, and would give the People cause to bless the Lord, for raising and Spiriting his Highness, and this Parliament, to be Repairers of our Breaches, and the Restorers of paths to dwell in.  
Prov. 14. 34. Isa. 32. 17. justice exalts a Nation. And the work of Righteousness shall be Peace.  
Prov. 3. 27. Withhold not good from them to whom it is due, when it is in the Power of thy hand to do it.  
judges, 5 23. Curse ye Meroz because they came not to the help of the Lord against the Mighty.
