In Mosul an up-to-date printing establishment was installed in which were printed the Scriptures and other books in Arabic, Syriac, and other languages. A seminary was founded for the benefit of Chaldean students destined for the priesthood. The education of girls was entrusted to the highly cultured Dominican Sisters of the Presentation of Tours, France. Not only did they assume charge of preparatory and normal schools but they also opened industrial schools for girls, especially for the working girls of the city. They also took charge of dispensaries where thousands of poor and sick people received free of charge the medicine and treatment which their condition required and which, before the arrival of these ministering angels of mercy, were not available. In view of all these facts is there anything surprising in the final return of the followers of Nestorius to communion with Rome?[324] The history of the Jacobites, of whom Marco Polo found many in Mosul--“Christians indeed, but not in the fashion enjoined by the Pope of Rome”--differs but little, except in one point of doctrine, from that of the Nestorians. This point of doctrine is in one respect the very opposite of the distinguishing dogma of the Nestorians. For, whereas the Nestorians divided Christ into two persons against the Catholic doctrine which maintained His unity, the Jacobites, contrary to Catholic teaching, asserted that there is in Christ but one nature and not two, the human and the divine, as decreed in 451, by the Œcumenical Council of Chalcedon.[325] It is because this heresy teaches the fusion of Our Lord’s humanity and divinity that it is called Monophysitism. And because, in its early stages, it was so ardently championed by Eutyches, an archimandrite of a monastery outside the walls of Constantinople, it is also known as Eutychianism. The Syrian Monophysites are usually called Jacobites, after Jacob Zanzalos, who was an early and zealous propagator of the heresy. So far as statistics are available the number of Jacobites is somewhat larger than was that of the Nestorians when the Dominicans began to lead them back to obedience to Rome. They are scattered throughout Syria and Mesopotamia and Malabar. Their Patriarch, who always takes the name Ignatius with the title of Antioch, resides at Mardin or Diarbekir on the Upper Tigris to the northwest of Mosul. Although they all talk Arabic, the Jacobites use the Syrian liturgy of St. James. In consequence of the missionary labors of the Franciscans, Dominicans, and Capuchins the majority of the Jacobites are again in communion with Rome under the name of Melchites or Syrian Uniates. Their Patriarch with the title of Antioch usually resides at Beirut. He has eight suffragans, most of whom live in Mesopotamia. From present indications the day does not seem distant when the Jacobites, like the Nestorians, shall once more be reunited with the See of Peter, from which they have so long been separated.
