TheSynod of Constantinople in 1484 was anEcumenicalsynod of theEastern Orthodox Church that took place from 1 September 1483 to 31 August 1484. It was the first synod to condemn theCouncil of Florence and defined the ritual for reception of Catholics to Greek Orthodoxy.[1]
After the 1453fall of Constantinople, theOttoman government organized the Patriarchate of Constantinople as a department within the Islamic state and supported its Orthodox heritage and anti-Catholic feelings with the political objective of moving the captured Greeks away from Western Europe.[2]: 86 The Patriarch of Constantinople at the time,Symeon I, served the interests of theOttoman Sultan, both during his second reign with his policy towardsTrebizond and, during his last reign, by convening a synod to formally ratify the condemnation of theCatholic Church.[3]
The Synod of Constantinople was convened by Patriarch Symeon I and lasted from September 1483 until August 1484.[2]: 67 [4] It was held in the patriarchalPammakaristos Church, in the presence of representatives of the Patriarchs ofAlexandria,Antioch andJerusalem (the latter sees then being under theMamluk Sultanate of Cairo). The main issue of the synod was the need to define a ritual for the admission to theEastern Orthodox Church of the converted from theCatholic Church. This issue was quite relevant in such years due to the conquests by the Ottomans of areas previously subjected toWestern rule (e.g. theDuchy of Athens) and to the Ottoman system of government of the minorities (themillet system) which subjected the Catholics to the civil authority of the Patriarch of Constantinople, causing numerous conversions to Orthodoxy.
The Synod, as preliminary remark, stated that theCouncil of Florence had been notcanonically summoned or composed, and so its decrees were null and void, and then approved a ritual for the reception for the converts which required theChrismation and an abjuration of the Council of Florence (but not a re-baptism).[5] Further, the council endorsed the positions expressed by patriarch Photius in thefourth council of Constantinople (879) and the decrees of thesynod of Constantinople of 1275 and rejected thefilioque.[6]
The 1484 Synod of Constantinople was the first synod to condemn the Council of Florence, as the so-called1450 Synod of Saint Sophia never took place and its documents are a forgery of the early 17th century.[1] However the decrees of the 1484 synod were not universally implemented and cases ofinter-communion between Catholics and Orthodox went on in theregions subjected to theVenetian Republic until the 18th century.[7] The later synod of Constantinople in 1755 made the requirements for Catholics and monophysite Armenians much harder and similar to the admission of heretics, requiring them to re-baptise under the Byzantine rite of triple immersion.[8]
