St. Theophylact was Archbishop of Ochrid, from about 1088 until his repose in 1108. As Archbishop of Ochrid, he occupied the position as head of an Autocephalous Church; the Bulgarian Patriarchate had previously been forcibly [and uncanonically] abolished by the Eastern Roman authorities years earlier; however, the Bulgarian Church maintained independence still with its own independent Archbishopric.
Some writers have noted the hostility that Greek speaking civil and clerical authorities had show to the usage of Slavonic, with, possibly, even attempts to suppress Church Slavonic in favour of the Greek language:
""The Greeks [i.e. Eastern Romans] adopted a policy of cultural assimilation in Bulgaria. John of Debar [last Bulgarian Patriarch of the First Bulgarian Empire] died in 1037 and after that the Archbishop of Ohrid was always a Greek. As an agent of the Emperor he had to implement the policy by introducing such changes as the use of Greek in the Bulgarian Church. The Greeks also destroyed Slavonic books, but there is little documentation to show the success of this policy. The survival of a number of Old Church Slavonic manuscripts, allegedly copied in the eleventh century by the Bulgarian and Macedonian scribes, suggests that the Archbishops also condoned the use of such texts. The best evidence that the Primate of Ohrid did not attempt to stifle Slavonic tradition is provided by Theophylact [+1109]. For a Greek who allegedly abhorred living in Bulgaria, it is remarkable that he wrote a biography of St. Clement of Ohride which he based on a Slavonic life of the saint. In it he also praised the work of SS. Cyril and Methodius."
