Hierarch Peter Chrysologus

NAME CORRECTION: the previous spelling "Peter Zlatoslov" is not supported by any source — all Russian-language ecclesiastical-scholarly sources (azbyka.ru, patristics articles) uniformly use the direct transliteration "Пётр Хрисолог" (Greek Χρυσολόγος, "golden-worded"). Unlike "Zlatoust" (a genuine calque of John Chrysostom's name), "Chrysologus" was never translated into Russian as "Zlatoslov" — this appears to be a later erroneous invention.

HONEST DATE CAVEAT: the date "July 30" without a clear style indication is almost certainly an uncritically carried-over modern Catholic (Gregorian) date, introduced after the 1969 calendar reform; no dedicated article on pravenc.ru or entry in the official ROC calendar (days.pravoslavie.ru) could be found, indicating no established feast day in Orthodox liturgical practice.

Saint Peter Chrysologus was born c. 380 in Imola near Ravenna and died there on July 31, 450. He became Bishop of Ravenna, renowned as an outstanding preacher — hence the epithet "Chrysologus" ("golden-worded"), established from the 9th century. He maintained close ties with Pope Leo the Great and corresponded regarding the case of the Constantinopolitan archimandrite Eutyches on the eve of the Christological controversies leading to the Council of Chalcedon. More than 170 of his brief, clear sermons survive. He was declared a Doctor of the Church by the Roman Catholic Church in 1729 under Pope Benedict XIII; venerated as an ancient Western hierarch of the pre-schism era.
