Repentance and the Restoration of the Icons
According to the synaxarion, when the Empress Irene and her son Constantine sought Paul's counsel concerning the succession to the patriarchate, he recommended Saint Tarasius, then still a layman serving as an imperial official, as the most worthy candidate, and he urged the convening of an ecumenical council. Paul's withdrawal and his counsel are remembered as preparing the way for the Seventh Ecumenical Council, held at Nicaea in 787, which condemned iconoclasm and restored the veneration of the holy icons.
Sources differ on the year of his repose: the Orthodox synaxarion tradition records that he reposed as a schemamonk in the year 804, while other accounts place his death shortly after his abdication. He is distinguished by the epithet "the New" from earlier patriarchs of the same name.
