Athanasius II Baldoyo

Athanasius II Baldoyo (, ), also known as Athanasius of Balad, and Athanasius of Nisibis, was the Patriarch of Antioch and head of the Syriac Orthodox Church from 684 until his death in 687.
Biography.
Athanasius was born at Balad, and studied Syriac, Greek, and sciences under Severus Sebokht at the monastery of Qenneshre, where he became friends with Jacob of Edessa. After becoming a monk at the monastery of Beth Malka near Antioch, he continued his studies, and was educated in philosophy. Athanasius was later ordained as a priest, and made his residence at Nisibis.
In the tenure of the Patriarch Severus II bar Masqeh, the church had suffered schism between the patriarch and a number of bishops over the issue of the right of archbishops to ordain suffragan bishops. On his deathbed, Severus authorised John, archbishop of the monastery of Saint Matthew, to reconcile with the errant bishops, and after his death earlier in the year, a synod was held at the monastery of Asphulos near Reshʿayna in the summer of 684. At the synod, the schism was brought to an end, and Athanasius was consecrated as Severus' successor as patriarch of Antioch by Ananias, bishop of Merde and Kfar Tutho.
Athanasius' consecration is placed in 684 (AG 995) in the "Chronicle" of Michael the Syrian and the "Ecclesiastical History" of Bar Hebraeus, whereas the "Chronicle of 846" and "Zuqnin Chronicle" erroneously give 687 (AG 999) due to confusion between Athanasius' consecration and death. In the same year as his ascension to the patriarchal office, he issued an encyclical addressed to rural bishops (chorepiscopi) and priests (periodeutai) on the relationship between adherents and other religious groups. In the encyclical, Athanasius forbade priests from baptising or giving the Eucharist to Julianists, Nestorians, and other sects. The encyclical also expressed Athanasius' condemnation of Christian women who married Muslims, but he did permit them to continue to receive the Eucharist, and encouraged clergy to ensure the children of these marriages were baptised, did not participate in Muslim festivals, and did not consume sacrificial meat.
Prior to his death, Athanasius instructed the bishop Sergius Zkhunoyo to consecrate his student George as bishop of the Arabs. Athanasius subsequently died in September 687. 687 (AG 998) is derived as the year of Athanasius' death from the histories of Michael the Syrian and Bar Hebraeus, whilst the "Zuqnin Chronicle" places it in 703/704 (AG 1015).
Works.
Athanasius was a prolific translator of Greek works into Syriac, including Porphyry's "Isagoge" in January 645, as well as an anonymous Greek text on logic. At the request of the archbishops Matthew of Aleppo and Daniel of Edessa, Athanasius translated nine treatises of the "Hexameron" by Basil of Caesarea in 666/667. In 669, whilst at Nisibis, he completed a translation of a number of letters of Severus of Antioch following a commission from Matthew of Aleppo and Daniel of Edessa. Severus of Antioch's second discourse against Nephalius, several homilies by Gregory of Nazianzus, and the book of Pseudo-Dionysius the Areopagite were also translated by Athanasius. He is also known to have translated several works of Aristotle, such as "Prior Analytics", "Topics", and "Sophistical Refutations".
In addition to his translations, Athanasius composed prayers of supplication, three of which are to be used at the celebration of the Eucharist, and prayers for the dead.
