CHAP. VII. (Book 7)
An Account of the Controversies on foot between the LATIN and the GREEK Churches in the Eleventh Century.
THO' The Latin and Greek Churches were not in a close Communion with each * 1.1 other ever since the Affair of Photius, yet they did not proceed to an open Rupture till the time of Pope Leo IX. and of Michael Cerularius Patriarch of Constantinople. This Breach began by a Letter which the Latter wrote in the Year, 1053. in his own Name and in the Name of Leo Arch-bishop of Acridia and of all Bulgaria, to John Bishop of Trani in Apulia, that he might communicate it to the Pope and to all the Western Church. In▪ this Letter they reprov'd the Latins. (1.) Because they made use of unleaven'd Bread in the celebration of the Eucharist. (2.) Because they Fasted on the Saturdays in Lent. (3.) Because they Eat the Blood of Beasts, and things Strangled. (4.) Because they did not Sing ALLELUIAH in Lent. At the same time Michael Cerularius order'd the Churches of the Latins who were at Constantinople to be shut up, and to deprive the Abbots and Latin Religious, who would not renounce the Ceremonies of the Roman Church, of the Monasteries which they held in that City.
This Letter of Michael being brought into Italy by an Officer of the Emperor Constan∣tine * 1.2 Monomachus, who went thither to carry on a Treaty with the Pope against the Nor∣mans, was communicated to Cardinal Humbert, who was at Trani; he turn'd it into Latin, and sent a Copy of it to Pope Leo. This Pope wrote upon that Subject a Let∣ter to Cerularius and to Leo of Acridia, wherein he extols the Dignity of the Church of Rome, and complains of the unkind usage which the Greeks had shewn to the Latins at Con∣stantinople without discanting on any of the particular Points. He only observ'd in ge∣neral, that the Diversity of Ceremonies is no lawful Foundation for the breach of the unity of the Church. This is the first Letter of Leo, of which we have made mention in another place.
The Greek Emperor, whose interest it was to hold it fair with the Pope, that he might * 1.3 still be Master of that little which he had in the West, wrote him a Letter, whereby he declares that he was willing to procure the Union of both Churches: And the Patriarch of Constantinople took notice to him likewise that he desir'd the same. The Pope who as much desired this reunion as the Greeks, as well for the Welfare of the Church, as because he was willing to be secur'd against the Normans in Apulia, the next Year sent three Le∣gats * 1.4 to Constantinople, viz. Cardinal Humbert Bishop of Blanchesolva, Cardinal Frederick Arch-deacon and Chancellor of the Church of Rome; and Peter Arch-bishop of Melphi. He sent them with Letters to the Emperor and to the Patriarch, wherein he commends the Zeal, which the Emperor express'd for the Peace of the Church, and complain'd of the Pa∣triarch's Proceedings against the Church of Rome, even at a time when he pretended to be desirous of Peace. These are the sixth and seventh Letters of Leo. In that which is di∣rected to the Patriarch he upbraids him with four Things of which mention is made * 1.5 be∣fore, and which 'tis not thought fit to repeat. This Letter is •…•…ated in January, 1054.
The Legats being arriv'd at Constantinople on the Feast of S. John Baptist, were kindly receiv'd by the Emperor Humbert, who was the Spokesman who presented to that Prince the Pope's Letters, and gave Michael that which was directed to him. He likewise presented to the Emperor a Writing which he had Compos'd in answer to the Letter of Cerularius,
