Patriarch Peter, as [[John III of Jerusalem|John III]]'s successor and following in his Orthodox position, convened in September 536 a [[synod]] in Jerusalem in which he proclaimed his orthodoxy and adherence to the [[Fifth Ecumenical Council|Council of Chalcedon]]. He agreed in the [[deposition]] of Anthimus I, the [[Monophysitism|Monophysite]] patriarch of Constantinople who was deposed that year.
In 544, emperor [[Justinian]] issued an edict condemning Theodore of Mopsuestia, Theodoret of Cyr, and Ive of Edessa, who supposedly were Nestorians, but who were never
[[excommunicate]]d and who had died in the fifth century. Peter signed the edict but included a proviso that if it would not be signed by the Pope of Rome, his signature would be invalid. Eventually, the emperor forced the Pope sign the edict.
Patr. Peter died in 544.
