Theophylact was an Eastern Orthodox archbishop of Ohrid. He is considered a saint. He lived from about 1055-1107.
He was involved in two of the causal primary disputes after the Great Schism of 1054 about the filioque and nature of bread Christ used at the Last Supper (either leavened-Greek or unleavened-Latin).
He absolutely refused to bend on the first issue, though acknowledging the Latins may have lacked clear specific language on the issue. On the second issue, he acknowledged that Christ would have used unleavened bread, but that it was not a binding tradition.
He is well respected for his exegesis of books of the Bible.
