Nicephorus Gregoras
However, the last of these councils, held in May 1351, conclusively exonerated Palamas and condemned his opponents. This synod ordered that the metropolitans of Ephesus and Ganos be defrocked and jailed. All those who were unwilling to submit to the orthodox view were to be excommunicated and kept under surveillance at their residences. A series of anathemas were pronounced against Barlaam, Akindynos and their followers; at the same time, a series of acclamations were also declared in favor of Gregory Palamas and the adherents of his doctrine. One notable opponent of Palamism was Nicephorus Gregoras who refused to submit to the dictates of the synod and was effectively imprisoned in a monastery for two years.
